"The first and fiercest punishment ought to fall first on the traitor, second on the enemy. If I had but one bullet and I were faced by both an enemy and a traitor, I would let the traitor have it."
— Corneliu Zelea Codreanu, For My Legionaries
You can commit war crimes. You can be a Loan Shark. You can even kick puppies on vacation, but if you betray someone who trusts you, you are the lowest form of creature there is. If this attitude is described from the victim's point of view rather than as the expected attitude of neutral observers, it would be Et Tu, Brute?. No matter which side they turn against, though, expect their former allies to carry some Abandonment-Induced Animosity.
This doesn't necessarily mean that the traitor is actually evil. A turncoat by definition only has their own advancement in mind, but someone who is a Defector from Decadence does so by turning on the obviously immoral team they previously worked for. This can even head into downright Moral Myopia with situations like gangsters treating people who work with the authorities as the scum of the earth for exposing their own criminal activities. Indeed, different interpretations of what constitutes loyalty and betrayal (and especially if one should remain loyal to an evil organization) make this a contentious issue in real life, at least if someone considers evil organizations worthy to contend with. This is obviously an In-Universe reaction and doesn't cover the author's and the audience's attitude towards it.
Sometimes Zig-Zagged or averted in Spy Fiction for fairly obvious reasons. Traitors from the good guy's team are evil, but traitors from the bad guy's team are sometimes sympathetic, depending on their motivation. In that case, it’s not the treachery itself, but the choice of sides that matters. When the enemy turns one of your own, it is more like Et Tu, Brute? In war stories, it's why The Quisling and his fellow collaborators are even more despised than the actual occupiers.
The idea of Sacred Hospitality is big on this. It's perfectly fine to kill each other on the battlefield, but luring someone into your home with the promise of protection just so you can kill them is truly despicable. Someone who believes this may also hold the views embodied in My Master, Right or Wrong or My Country, Right or Wrong.
If even those who profit by the treachery treat the traitor this way, that is Rewarded as a Traitor Deserves. Unless they betray them for self-serving reasons, making them the treacherous ones. A villain who makes a point to defy this will insist that I Gave My Word. Contrast Finding Judas and Regretful Traitor, which are different ways traitors are portrayed sympathetically (at least to the audience). This is one of the reasons why people believe that Spies are Despicable, as treachery is part of the job. See also The Oath-Breaker for general cases of people breaking sworn promises, regardless of how they're treated for it, and Rash Promise, which is often a means of teaching this moral.

Anime & Manga
- Fairy Tail: Being a series that runs on The Power of Friendship, nothing quite establishes a villain's vileness like when they prove fully willing to betray their comrades for incredibly petty reasons. Best exemplified in the Nirvana Arc when Brain shoots Cobra, a loyal minion who was on the verge of killing Natsu despite having been taken off-guard, for the crime of taking too damn long to finish off "trash" and merely coming to the verge of defeat rather than dominating as expected. This betrayal especially hits home when Cobra hears Brain's thoughts and realizes that he always viewed the rest of his loyal guild as disposable trash to be replaced at a good opportunity and then Brain laughs when he realizes he heard that. Natsu, who witnesses all of this, only views Cobra with pity as he collapses and calls out Brain on wasting his own allies and viewing them as puppets. When Cobra gets revenge on Brain seven years later, none of the rest of the guild cares since they learned Brain never cared about them, not even the most loyal of Brain's men and self-proclaimed son, Midnight.
- In Fate/Apocrypha, Avicebron switches sides to the Red Faction, on the condition no harm is to come to his master. Chiron initially believes this is because of Undying Loyalty. However, Avicebron proves him wrong by using said master as the magical core of his colossal golem. An infuriated Chiron, incensed at the depths he's sunk to complete his dream, shoots an arrow straight into his forehead. This act is considered so horrible that Avicebron in his Fate/Grand Order incarnation considers it one of the worst things he has done.
- The Straw Hats in One Piece have no heroic goals or motives whatsoever and only tend to do good things out of self defense or because a friend is involved. As such, they are indifferent to theft and only marginally concerned with murder, but they hate seeing anyone mistreat their friends or underlings and will go out of their way to punish traitors or bad bosses.

Comic Books
- Deathstroke once rewarded Cheshire for selling out her own team by shooting her in the gut and leaving her for dead while noting his utter disgust with her actions.
- Harley Quinn: In the 2000 series, Harley, while hardly a good person, is still fairly sympathetic for most of it. The event portrayed as her Moral Event Horizon happens at the end of the final story arc. Basically, a little girl has a code to a vault inscribed on her retina that a bunch of bad guys want. Due to how the "inscription" works, after the code is scanned out of her retina, she needs eye surgery within a few hours or will go blind for life. While Harley starts out claiming the girl means nothing to her, she starts to actually care about her and promises not to let her go blind. At the end, she lets her go blind anyway and takes the money. Even Harley realizes what a heinous thing she has done, as she later meets the now-blind girl in the park and is very clearly Trying Not to Cry Tears of Remorse, and ultimately feels so guilty she returns to Arkham Asylum on purpose.
- The Life and Times of Scrooge McDuck: Scrooge meets a fair share of nasty villains who are out for his blood and steal his riches, but he considers Flintheart Glomgold the worst of the lot because the latter had betrayed him by stealing his belongings and leaving him for dead in the African wilderness after Scrooge went out of his way to save his life and befriended him.

In Tangle and Whisper #4, Tangle confronts him over it, and is absolutely livid when he replies that he never even considered them friends or comrades.
Fan Works
- Cheating Death: Those That Lived: As far as most residents of the Districts are concerned, the only time it's considered justifiable for somebody to kill their own District partner in the Hunger Games is if it involves a Mercy Kill, or if they're your final opponent after everyone else has been dealt with. This has led to some of the Victors being deeply despised, such as the Dirty Coward Logger.
- Dragon Ball Z: Dynasty: While they are involved in planetary conquest and desolation as the rest of the Saiyans, the Warhammers were a tight-nit group of outcasts who grew to care for each other under Cassava's leadership.

Responding her specifically, it shows moments of her own life and happenings from the first movie in the form of ice sculptures, including the villains. She's amused and happily dances along when seeing the dancing statue of the first villain, a magic-hating bigot who tries to kill her, but when she sees the image of Prince Hans seducing her sister, so he could one day kill Elsa and use Anna to ascend the throne, and directly left Anna to die, Elsa's smile instantly drops and she contemptuously destroys the effigy backhandedly.
- Don Bluth's Titan A.E. has the Plot Twist that The Hero's mentor, Captain Korso, sold him out to the Drej, convinced that humanity is "circling the drain."

Films — Live-Action
- Absolute Power (1997): Richmond's affair with a married woman and his subsequent murder of her would have been bad enough by itself, but she was also the wife of Walter Sullivan, a life-long mentor of his who played a key role in getting him into the Presidency.

- Doctor Ben Sobel from Analyze That, loses his composure after seeing so many actual crimes and backstabbing during two movies.
Ben: I can't take it anymore! That's what I hate about you fucking sociopaths! You just keep changing the rules to suit yourselves. Well, not this time, you anti-social asshole. You fucked with the wrong shrink!
- A major theme in A Few Good Men where different moral codes and conceptions of treachery clash with each other.
- Colonel Jessup ordered the Code Red on the victim, Willy Santiago, because he tried to exchange incriminating information against a transfer, but then automatically sacrifices those who loyally apply that order.
- Lieutenant Kendrick candidly declares in court that the victim died because he has no honor and that Dawson once committed a crime by giving food to a punished man.
- Lieutenant-Colonel Markinson commits suicide because he can't bear his guilt and refuses to testify against his superior.
- After Judge Randolph orders Downey and Dawson to be dishonorably discharged from the Marine Corps, the latter concludes they indeed betrayed the victim and the principles they were supposed to defend as Marines.
- The General's Daughter (1999): The film combines this trope with Rape Is a Special Kind of Evil. A female officer, the eponymous General's daughter, is revealed to have endured a horrific gang rape from male soldiers while she was enrolled at West Point. The rape was already traumatizing, but she might have recovered from it until her father betrayed her by covering up the event to get a promotion for himself broke her psyche completely. The investigator (played by John Travolta) ends up concluding that it was her father who really killed her and promises that he'll prosecute both him and the rapists for their crimes.
Brenner: Someone once asked me what's worse than rape. Now I know the answer. Betrayal.
- The traitors are purged in the climax of each movie of The Godfather Trilogy.
- During the hospital raid in Hard Boiled, Mad Dog told Alan there are two people he hates the most; the cops, and creeps who betray their bosses. This was after he found out that Alan was an undercover cop, filling both criteria. Unfortunately, Johnny Wong, Mad Dog's own boss, proves to be a monster who Mad Dog has to betray himself in order to stop him from massacring innocent people, leading to Mad Dog's own death.
- This is a central theme in I Shot Jesse James. Bob is cursed and spat upon by nearly everyone for shooting his longtime companion Jesse James in the back, even though James was a thief and murderer. It doesn’t help that people still aren’t quite willing to let go of their romanticized image of James as a Robin Hood-style rebel.
Literature
- In the Arcia Chronicles, treachery is treated as one of the worst sins: it is a treachery that sets in motion events that culminate in The End of the World as We Know It, and the resident Horsemen of the Apocalypse are reincarnations of four kings who betrayed their loyal subjects and friends during their lifetimes.
- Brother Cadfael: During the Forever War between Queen Maud and King Stephen, she sends her most trusted messenger with highly personal papers and jewelry to get help from her French relations, but the messenger is never seen again. Hugh Beringar looks for the murderer despite his fealty to Stephen and is horrified to realize that the messenger never died, but took on another identity as a hermit until he could escape, murdering a man who could have recognized him and getting killed in turn. He calls off the search in disgust and bears no grudge against Cadfael (who'd already figured it out) for letting the traitor's murderer get away.
- The Divine Comedy: The Ninth Circle of Hell, Cocytus, is a vast frozen lake in which traitors are entombed. In the center of it all is Lucifer himself, trapped up to his waist, his wings beating in a futile attempt to free himself, but the winds freezing the water, and his three heads are chewing on Brutus and Cassius (who betrayed Julius Caesar), and Judas Iscariot (who betrayed Jesus). Cocytus is the lowest circle of Hell (the highest, Limbo, contains virtuous pagans, good people who either lived and died before the existence of Christ or simply weren't baptized), thus according to Dante, there is no sin worse than betrayal.
- Harry Potter:
- Rereading the third book after the seventh makes Snape's hatred of Sirius much clearer: In addition to his grudge against him from his schoolkid bullying, he, like everyone else, thought Sirius had betrayed the Potters to Voldemort, and thus was partly responsible for Lily's death.
- Taken slightly too far in the fourth book, where Ron considers Hermione dating Viktor Krum (the Durmstrang champion) as aiding the enemy to cover his jealousy (causing a Broken Pedestal moment, as he'd been a big fan of Krum's up to then). Hermione doesn't see what the big deal is, but then she also doesn't get why Quidditch is seen as a good thing when all it does is cause tension and resentment between Houses (she's not wrong, but as the viewpoint character is a Quidditch player...).
- Peter Pettigrew is on the receiving end from both sides: When Sirius realizes Pettigrew survived his betrayal of the Potters, he becomes obsessed with hunting him down and avenging them, nearly succeeding if it weren't for Harry interceding. Pettigrew sacrifices his living hand to bring Voldemort back and is rewarded with a magical silver hand. In the seventh book, Pettigrew has a moment's hesitation (due to Harry saving his life four years prior) when carrying out Voldemort's orders, which is enough for the hand to strangle him.
- The fake Mad-Eye Moody claims he can't abide traitors, which is why he looks down on former Death Eaters like Karkaroff and Lucius Malfoy. He's even telling the truth: they're Death Eaters who escaped imprisonment by claiming they were Double Agents or mind-controlled, while Barty Crouch Jr. went to Azkaban along with other loyalists before escaping to serve Voldemort in disguise.
- In Harry Potter and the Order of the Phoenix, the curse Hermione gave to anyone ratting on Dumbledore's Army was a permanent marking on the face.
- Mass Effect: Ascension: Golo is a quarian who was exiled from the Migrant Fleet for selling over a dozen young quarians to the Collectors for profit, and now seeks revenge against all quarians for "betraying" him. Even the human supremacist Cerberus operatives who are working with him and need his help for a strike against his race all universally despise him on principle for betraying his own people for personal gain with one of them outright turning on Cerberus both for the benefit of his adopted daughter and for associating with such a wretched individual.
- In Reflections of Eterna (by the same author as Arcia Chronicles), betrayal often has massive supernatural consequences, such as the utter obliteration of the Nador Duchy by freak earthquakes after Richard Oakdell (the Duke of Nador) betrays his suzerain (and implied-to-be the rightful king) Roque Alva at a Kangaroo Court.
- This viewpoint is common in Westeros, the main setting of A Song of Ice and Fire.
- Among many nasty feudal overlords, the houses Frey and Bolton stand out as the least likeable, because they are traitorous. The mercenary captain Vargo Hoat lost his chance of a political career in Westeros because of Culture Clash: as a native of Essos, he thought switching sides is okay for him. It wasn't, and his former allies the Lannisters were particularly intolerant to this.
- One particular form of treachery is especially reviled in Westeros, namely violating Sacred Hospitality. The aforementioned House Frey became hated by all of Westeros because of that transgression (the victim was not just anyone, but their king, making it also high treason for a double whammy).
- Jaime Lannister, a knight of the Kingsguard, became famous for slaying King Aerys the Mad. From our perspective, that was a noble deed, especially considering the fact that the king planned to burn his capital down with all its citizens. However, as a member of the Kingsguard, Jaime swore to serve and protect his king, and, by killing him and saving countless lives, he committed a traitorous act. This made Jaime infamous and gave him the ignoble moniker of "The Kingslayer", even among former enemies of King Aerys.
- In the legend of the Rat Cook, a cook of the Night’s Watch killed the king’s son and served him to the king as dinner. He was then punished by the gods by being turned into a rat. However, he was not punished for murder or cannibalism, but for betraying his guest and breaking the Sacred Hospitality.
- Bastards are often stereotyped as treacherous and untrustworthy.
- The Sword of Saint Ferdinand: Benalbamar, King of Granada, may not like Castilians, but he is utterly repulsed by his mole Pedro de Guzmán, since the man is betraying his country, his king and his religion for a handful of golden coins. Benalbamar hates spies and traitors, but he believes them to be necessary in time of war (as long as he has to deal with them as little as possible).
Live-Action TV
- Agents of S.H.I.E.L.D.: Even when there are wheels within wheels rolling and he holds many secrets (and understands other people have them), if there is soemthing that will drive Phil Coulson up the wall immediately, is even thinking of stabbing the team in the back.
- In Angel, Wesley is manipulated into kidnapping Angel's son, Connor, believing Angel was going to eat Connor. This act of betrayal causes a big schism between the two and other members of the team. Not even having Wesley being in the hospital with his throat slit stopped Angel in attacking him. In "The Price," Gunn and Cordelia even state outright that they don't care about Wesley's side of the story or why he stole Connor; he betrayed their trust, and that's all there is to it.
- Lilah offered Wesley a job at her demonic law firm by gifting him a centuries-old copy of Dante's Inferno, and reminding him that no matter how much of a good guy he thinks he is, he committed the ultimate sin.
- Babylon Five: Michael Garibaldi finds himself on both sides of this. At the end of the first season, he's shot In the Back by his second, Jack. When it comes to light, he goes to confront him, demanding to know why, and promising to be the one to push the button when Jack's Thrown Out the Airlock. In the fourth season, Garibaldi, who's been programmed by Bester's telepaths, arranges for Sheridan to be apprehended by Clark loyalists. When she hears about it, Ivanova orders Garibaldi shot on sight if he ever shows his face again.
- In Firefly, Mal references the harsh punishments for traitors while he's ready to execute Jayne for ratting the Tams out to the Feds in "Ariel":
I hear tell they used to keelhaul traitors back in the day. Now I don't have a keel to haul you on...
- In Lexx, Stanley Tweedle is known as the "Arch Traitor" (and hated enough by La Résistance that they're more willing to kill him than the Big Bad's guards) because...he got caught by some Space Pirates and gave away some security codes, after being tortured for them. Whenever it comes up, it's usually Played for Laughs.
- The Lord of the Rings: The Rings of Power: Sauron kills quite a few people personally in Season 2, and on the surface, it seems rather random. However, most people he kills have betrayed their master. Mirdania, for all her good intentions, betrays Celebrimbor by siding with Annatar. Glug betrayed Adar by siding with Sauron. Adar and Waldreg both turned against Sauron. You could even make this argument about the people of Eregion, who Annatar tricks into betraying Celebrimbor. It certainly seems the Dark Lord has contempt for disloyalty.
- The Man in the High Castle: In the Axis-dominated world, execution is already a disturbingly common punishment for dissidents, so traitors to the Nazi or Japanese causes are given an outright Cruel and Unusual Death. For instance, after a mole within the Kempeitai is exposed by Chief Inspector Kido, the traitor is bayonetted to death by a dozen soldiers charging on him in turns.
- Robin of Sherwood: Will Scarlet holds a vendetta against the outlaw Roth for leaving him to die against French soldiers during their time in the army after Roth begged Will to save him from them.
- In Roots (1977), Chicken George trusts his masters to never hurt him and his family, so when Tom Moore threatens to kill them all after the Nat Turner rebellion, it wounds him deeply. Even worse, George finds out that he's actually Tom's son, and yet Tom still sells him away to England.
- Stargate SG-1:
- Jaffa who turn on their Goa'uld master are branded as "Shol'va" and are outcasts among Jaffa—especially if they were First Primes such as Teal'c. The whole Goa'uld power system requires the unto-death subservience of their Slave Race armies, so of course they would take special measures to discourage turncoats.
- The goa'uld Ba'al betrays his master Anubis when he discovers that Anubis means to wipe out all life in the galaxy, Ba'al included, and begins to work with the Tau'ri to stop him. Anubis finds out but decides that having Ba'al be witness to the coming end would be more fitting than straight execution.
- In Star Trek, the three pillars of Klingon philosophy are duty, honor, and loyalty. Officially, the Klingons play this trope straight.
- Worf does, but he's a particular case. Firstly, his parents died in a treacherous attack by the Romulans who had Klingon accomplices. Secondly, since he was adopted by human parents, he developed an idealized conception of the Klingon way of life.
- This aspect wasn't yet established during the original series, but the trope is still Played Straight by Kang. He has always scrupulously respected the Organian treaty, so he's pretty angry when his ship's disabled by what seems to be an unjustified attack from the Enterprise.
- Overall, a lot of treacherous Klingons appear onscreen. Sometimes, their strategy is accusing the adversary of treachery.
- In Klingon society, losing honor is officially worse than being killed and traitors are usually stripped of their honor.
- The episode "The Drumhead" starts with a Klingon who involved in espionage for the Romulans, but there's also the fight between Admiral Satie, who believes the end justifies the means to find imaginary traitors, and Picard, who points out that her methods betray the principles of Federation justice.
- The West Wing: Sam Seaborn wrote his thesis about a man named Daniel Gault, arguing that Gault had been falsely accused of spying for the Soviet Union. Gault's granddaughter reaches out to Sam to help her seek a posthumous pardon for him. This leads to Sam being personally shown a heavily-classified file by the head of the NSA that proves that Gault was guilty. Sam is enraged by this, and delivers an impassioned rant to a co-worker about how treason is a crime against those who sacrificed their lives to build America and the ideals it stands for. While he's clearly projecting some of his anger over a dispute with his father, it's clear he truly believes Gault's actions (which resulted in the murder of a woman who was about to expose him) to be utterly despicable.
- The Wire: In season 4, Randy Wagstaff, an eighth-grade student in the Baltimore public school system, talks to the police after witnessing a murder perpetrated by the Stanfield drug gang. After word gets out, he is immediately targeted by his peers as a snitch, culminating in his house being firebombed and his foster mother permanently disfigured. Randy eventually has to go back to the badly-funded group home he already stayed in for years.
Religion
- The Bible:
- Judas's betrayal of Jesus, as recounted in The Four Gospels of The Bible. This betrayal was arguably necessary, as Jesus had to die to wash away mankind's sins, and rise again on the third day. Even so, Judas still breaks down in utterly horrified remorse when he realizes he's killed an innocent man, followed by — in at least one account — hanging himself from a tree shortly thereafter.
- In Mark 13:12 this is considered a sign of the end of the world:
Now the brother shall betray the brother to death, and the father the son; and children shall rise up against their parents, and shall cause them to be put to death.
Tabletop Games
- In Ironsworn, iron vows are the most sacred of promises in the Ironlands. If one forsakes a vow, such as betraying the person they vowed to, it’s considered the "worst sort of failure." And if you die without fulfilling a vow? It can give unlife to a metal construct called an Iron Revenant, which cannot be stopped until it completes your unfinished business.
- In Paranoia, all "commie mutant traitors" are to be immediately executed.
- Princess: The Hopeful: The Princesses of the Court of Storms despise the Court of Tears for abandoning them to the Darkness during Downfall, to the point where fighting Tears is considered equivalent to fighting the Darkness itself by the rules of Storms magic (A Princess of Storms receives the same bonuses to attacking followers of Tears as she would receive if she were attacking a creature of the Darkness, but she also suffers the same sanctions if she shows mercy to a follower of Tears or retreats from battle with one).
- Count Strahd von Zarovich's infamous Act of Ultimate Darkness from Ravenloft was the betrayal and murder of his brother Sergei on his wedding day so that he could have Tatyana, the woman both men loved, for himself.
- Warhammer 40,000:
- Averted with Tzeentch, god of sorcerers, schemers and backstabbers, and his followers, for who betrayal at the worst possible time means everything is going Just as Planned.
- Khorne is the god of battle, rage and blood, and his followers don't consider it treason when they attack their own side (since blood spilled in battle strengthens Khorne). However, one of Khorne's greatest demons attacked him once (due to Tzeentch's manipulations), Khorne ripped his wings off and left him to slaughter for eternity without hope of being taken back.
- Every Imperial unit gets the Hatred special rule when fighting against gue'vasa (human auxiliairies serving in the Tau army). Willingly serving a xenos species is one of the highest forms of treason, never mind that some of them are descended from human worlds abandoned by the Imperium.
- Even Orks get in on this one, at least when the person betrayed happens to be the Worthy Opponent of their Prophet. Long story short, a soldier attempts to sell out Sebastian Yarrick to Ghazghkull Mag Uruk Thraka who does not take kindly to this at all and promptly throws said soldier to his personal Mad Doc for A Fate Worse Than Death.
Toys
- BIONICLE: The Dark Hunters are mercenaries willing to intimidate, steal, murder and mutilate all the live long day, but even they looked down on Nidhiki for turning on his fellow Toa, and had Roodaka forcibly mutate him to make sure he didn't decide to jump ship from them as well (a wise decision, since he was in fact planning to do just that as she hit him). The Shadowed One even admits that he dislikes traitors (since treachery implies he's not in control)...but he despises incompetent ones.
Video Games
- Assassin's Creed III: When Benjamin Church, a member of the Colonial Templars, defects to the British Empire, his former boss, Haytham Kenway, was pissed, to say the least. This results in him forming an uneasy alliance with his son Connor, an Assassin, to try and bring him to justice.
- Batman: Arkham City: Talia al Ghul is angry at Bruce and said he and her father deserve each other. Two minutes ago, she was the hostage of her own father. On the other hand, Bruce manipulated her because he needed Ra's al Ghul's blood to save a lot of lives. Of course, the al Ghul family doesn't have the same moral code as Batman.
- Batman: Arkham Origins: One of the conversations between three Joker Thugs and one Black Mask holdout indicates that Sionis used to pull Secret Test Of Characters on his own men by having a few of his men go around and do pretend defections. If they defected or betrayed him, he would have them killed. The Black Mask holdout even admits he's seen what Sionis has done to traitors.
- Command & Conquer: Tiberian Sun: After Anton Slavik is rescued by the other members of the Black Hand from his would-be execution by General Hassan (who is secretly on GDI's payroll), he returns to the bridge of his command ship and confronts the guy who sold him out. The traitor can barely get out a single line because Slavik shoots him on the spot. He's proud to engage in war crimes for the cause, but Slavik despises disloyalty with a fiery passion. He later publicly executes Hassan himself.
- In Crusader Kings II and III, traitors can be freely imprisoned by their liege lord and can be stripped of all their titles and then be banished, stripping them of their gold too, without upsetting any of your other vassals. To compare, murderers, rapists, and homosexuals can only be imprisoned, with any other action against them leading to your vassals becoming majorly pissed. To be considered a traitor, a vassal must openly go to war with his liege lord and thus break his feudal oath. This made civil wars extremely gamey, as players could just annoy vassals whose titles they desired until they revolt and then just steamroll them (although it becomes problematic if they convince your other vassals to revolt too). A patch then downplayed the traitor penalty, but it still is much harsher than any other punishment.
- Doom Eternal: The Night Sentinel, Valen the Betrayer, in the past betrayed his kin and led the forces of Hell to their homeworld of Argent D'Nur, in exchange for the resurrection of his son, which led to the planet's destruction and most of the Night Sentinels being wiped out. Even the demons considered his treason "wretched", and as punishment, brought his son back as the Icon of Sin (because Valen didn't specify how he wanted his son back).
"For his payment, the Betrayer's son was returned to him in our form, and the Icon of Sin was brought upon the heathens. His vengeance was swift and merciless, for the wages of treachery are suffering."
- Among goblins in Dwarf Fortress, treason is the sole act which their ethics consider as a wrong; all others, including murder, are "personal matters."
- The Friends of Ringo Ishikawa: Ringo firmly believes that nothing is worse to deal with than somebody who's betrayed your trust, complaining about the events of the Anna Karenina Expy he reads for his Literature class.
- In Grand Theft Auto V, Token Evil Teammate Trevor is a Woobie, Destroyer of Worlds who's committed nearly every crime in the book, but at the top of the short list of things he will not abide is treachery. It's for this reason that he held a massive grudge against Michael for Faking the Dead without telling him, and temporarily turns on him for letting his other Best Friend Brad die in his place and not tell him about that either.
- Guns, Gore & Cannoli: Vinnie Cannoli may be an unrepentant mobster who casually kills anyone in his way, be they gangsters, police, or even US Army soldiers, but he's absolutely loyal to a fault.

Just take a look at how Vinnie dealt with Joe Barista and Frankie the Fly, who both betrayed him for personal benefit and riches.
- Heroes of Might and Magic: Orcs in the Ashan setting are Half Human Hybrids who were created by infusing demon blood into human criminals, and were first used as demon-slaying shock troops in human armies and later as a Slave Race.

Unfortunately, said angara's actions have been found out by Kadara's mob boss, Sloane Kelly, and she's planning to give him the "head, spike, walls" treatment (not because she cares about the Moshae herself, but the angara living in the port do). Whether Ryder saves him or not is up to the player, but if they let him die, the Moshae is appalled, describing his actions as "inexcusable, not unforgivable".
- In Metal Gear Solid V: The Phantom Pain, the player can gas enemy soldiers, murder innocent animals, shoot your dog (though it'll always live,) and even develop a nuclear arsenal, but the evil the game prevents you from doing is shooting your own teammates. In a mission that forces you to Mercy Kill those infected with a parasite, with plenty of them begging you to, the only character that tries to call you out on it is clearly the one who allowed this to happen, which is why everyone else ignores him and puts him on trial afterward.

- Overly Sarcastic Productions: Discussed in Red's Betrayal Trope Talk. She notes that betrayal can, depending on who's doing the betraying, who's being betrayed, and why, be a heroic act- for example, a mook becomes a Defector from Decadence when their bosses cross a moral line- but for the most part, betrayal is a worse black mark on a character than being a villain from the start, and traitors are often the most hated characters in and out of universe.
Traitor: Why does everyone want to redeem you and not me? I've actually been a good guy!

Western Animation
- Parodied in Robot Chicken when Billy Dee Williams is at the grocery store and is flattered for being recognised by the other customers as the heroic Lando Calrissian, only for them to say that he wasn't really that "heroic" because he betrayed Han Solo and his friends. Billy Dee laughs it off and defends the decision as a Forced into Evil situation at worst since Darth Vader had taken his city hostage and he didn't really have a choice, plus he successfully bought time to save everyone else by doing so and rescued Han at a later date, but the customers don't buy it and Williams gets angrier as people always call Lando a traitor and he's sick and tired of it. Eventually he gives up as nobody is convinced. Even funnier, the sketch is a parody of actual fan interactions Williams had had in real life!
