History Main / BlackandWhiteInsanity

** [[spoiler:Akira Konoe]] has this as his greatest flaw, due to being what the Thieves would be if they didn't have each other to pull themselves back from the brink. He believes that he's a hero and that it is his duty to root out Japan's corruption. Therefore, whatever he does in pursuit of that goal is heroic (even if it involves using EMMA for mind control via stealing desires), and anyone who opposes him must be a villain who should be dealt with by any means necessary, even if they're the Phantom Thieves and are dismantling Jails because having one's desires stolen can ruin one's life (such as people bankrupting themselves to by Alice merch or Ango's book), and the Jails trap the Monarchs within their own trauma. There's a reason that his theme sin is Pride.

** Rorschach was meant deliberately as a comment on Creator/SteveDitko's [[WithUsOrAgainstUs more fanatically Objectivist]] characters. This is clearly reflected in his ExpressiveMask, where the black and white never mix. [[spoiler:This also led to his death, as he refused to compromise and decided to tell the world the truth despite knowing it would [[UtopiaJustifiesTheMeans only make all the deaths from the plan meaningless and will put the world on the brink of nuclear annihilation]]. Which is why Dr. Manhattan killed him in order to prevent him from doing so]].

** Daenerys shows signs of this during her SlaveLiberation, particularly in Meereen, when she starts dealing out vengeful punishments to the ruling class with the rationale that it is justice because they deserve it because they are evil, with no thought to how much or little the individuals involved were actually responsible for. Jorah is eventually able to talk her down, reminding her that he used to be a slaver himself. More subtly, there is her mounting paranoia that has come in as a result of being betrayed and used all her life by Viserys, Illyrio Mopatis, Mirri Maz Duur, the Qartheen, and later the fact that Jorah was initially a spy, which has hardened her stance. She still persisted at first in thinking of Robert Baratheon as TheUsurper and remains in the dark about the kind of person her father truly was, believing that the people who deposed him were evil and without cause. By Season 5, however, she has come to be aware of her father's insanity, with Tyrion Lannister -- now a trusted advisor -- informing her of why Jaime killed her father. Now, Dany openly refers to her father as terrible. [[spoiler:By Season 8, she's slid back into this, and eventually it gets her killed because it would have turned her into almost as bad a tyrant as her father.]]

* A Music/{{Vocaloid}} music video called [[https://www.youtube.com/watch?v=HQKYbBU4sPo "Super Hero"]] has the title character Kagamine Len choose to become a superhero like his idol on a cartoon show in order to administer justice. Over time, he finds the real evil lies in the government and tries to destroy the system for the greater good.

* In another Vocaloid song, [[https://www.youtube.com/watch?v=ZW-6U5bCyS4 "Karakuri Burst,"]] Kagamine Len states that his views of morality are separated only by 'black and white'.
* [[RuleOfThree And yet another Vocaloid song]], "The Monochrome Mentality", is all about this. vflower and Gumi both claim that an unnamed character is either pure evil or pure good respectively, and Maika bemoans this line of thinking.

* On the ''WebVideo/DreamSMP'', since the [[TheExile Pogtopia arc]], when his mental health took a ''[[SanitySlippage massive]]'' hit,[[note]]His [[TookALevelInCynicism mental spiral]] technically [[CynicismCatalyst kick-started]] after Eret's betrayal in the L'Manburg War for Independence, but it was heavily exacerbated by Schlatt exiling him and Tommy from the country they founded [[TyrantTakesTheHelm after becoming President]].[[/note]] [[FallenHero Wilbur]]'s worldview has been cleanly split in half, between "heroes" and "villains". This is most clearly shown in how he treats both Dream and himself.
** In Pogtopia, Wilbur initially considered himself the hero, and [[PresidentEvil Schlatt]] the villain. However, after hearing that Schlatt was planning to hold a festival in Manburg meant to be a nice event for his citizens, Wilbur realized that taking Manburg back from Schlatt wasn't as morally white as he'd first assumed, leading him to [[InsaneTrollLogic come to the conclusion]] that ''Schlatt'' was the hero and ''he'' was the villain. Even when the festival turned out to be a front for [[spoiler:Tubbo's execution]], Wilbur had already leaned so hard into [[ThenLetMeBeEvil becoming the best villain the server had ever seen]], that he didn't even consider walking back on his stance.
** [[spoiler:After regaining Ghostbur's memories, Wilbur was initially ''furious'' at Dream because of [[WouldHurtAChild his treatment of Tommy in exile]], and even outright told Tommy that he would've murdered Dream on the spot if he'd been there instead of Ghostbur. However, after being saved from the Afterlife by Dream, he seems to disregard the horrific abuse Dream put Tommy through and outright proclaims him a hero, giving a long speech about how his quest for power wasn't for power's sake, it was to prevent the rest of the server from filling the power vacuum Wilbur left behind. He snaps out of it when he learns just ''[[DrivenToSuicide how]]'' badly Exile went for Tommy.]]

While this is almost always done in settings that are not of BlackAndWhiteMorality themselves, exceptions exist. In such cases, a LawfulGood AntiHero suffering from Black and White Insanity can be very disturbing indeed in the eyes of their fellow LawfulGood real heroes.

A character suffering from Black and White Insanity is likely to reason in FalseDichotomies, keeping their worldview coherent by applying huge quantities of InsaneTrollLogic and meeting criticism with {{Abomination Accusation Attack}}s. Black and White Insanity might also be what makes a WellIntentionedExtremist, well, an ''extremist'', with particularly dogmatic or unhinged examples crossing into TautologicalTemplar. This kind of insanity is pretty much the characteristic of the ObliviouslyEvil KnightTemplar. CharacterDevelopment might lead to the insane one becoming a TroubledSympatheticBigot. A justice system that operates on Black and White Insanity believes that AllCrimesAreEqual.

Contrast BlackAndWhiteMorality (for settings where the world actually operates in a way that makes this kind of worldview completely rational). A [[DesignatedHero failed]] [[DesignatedVillain attempt]] at BlackAndWhiteMorality will make the main character come across as suffering from Black-and-White Insanity. Contrast GreyAndGrayInsanity for when a character's mental instability has to do with too much moral ambiguity as opposed to a black and white worldview.

'''Note: This trope is about characters who have a black and white worldview AND are mentally unstable.'''

* In ''Anime/ConcreteRevolutioChoujinGensou'', [[AstroClone Earth-chan]] subscribes to extreme black and white morality. She views any improper behavior, even anything as innocuous as a white lie, as absolutely Evil, and she cannot even understand why anyone would willingly lie. Likewise, she cannot understand someone trying but failing to live up to a moral ideal -- any failure to measure up is in her eyes a willful embrace of Evil. This attitude is shown to be at odds with a world filled with shades of grey and results in Earth-chan coming to hasty conclusions about who is in the right and taking actions that solve the immediate situation but don't actually address the underlying problem -- for instance, trying to address the problem of pollution by destroying a factory's smokestacks and then flying away with the satisfaction of a job well done, not comprehending that the factory will simply fix the smokestacks and continue as usual.

* ''Manga/HunterXHunter'': Gon is a case of this mixed with BlueAndOrangeMorality. His black and white views stop him from handling the fact that some of the people he considers 'bad' have redeeming qualities or do in fact care about others. The greatest example being when he confronts Pitou, who was in the middle of healing someone. It throws him into a mental breakdown as he is unable to accept that someone he hates can do good.

* In ''ComicBook/{{Logicomix}}'', [[https://it.wikipedia.org/wiki/Gottlob_Frege Frege]] is totally honest and devoted to truth and logic. Sadly, this devotion combined with IgnorantOfTheirOwnIgnorance leads to Black and White Insanity in the form of a StrawVulcan despite for women and Jews. On the whole, this makes him a TroubledSympatheticBigot who is desperately trying to do the right thing.

* ''[[https://archiveofourown.org/works/43468338 Prompt: Self Destruction]]'': Chat Noir believes that those that help Marinette and stop [[ManipulativeBitch Lila]] are good and those that fail to so are Marinette's enemies, a line of thinking that concerns Marinette herself. Just to emphasize the insane part, he applies this morality to ''himself''. He sees his hero identity as good since he help Marinette exposed Lila and his civilian identity as Adrien as "evil" because his high road advice [[UnwittingInstigatorOfDoom nearly led Marinette to be framed and expelled by Lila]], despite not knowing how bad Lila was until after the attempt. Plagg calls him out on how unhealthy and insane that line of thinking is.

* In ''Film/TheLedge'', Joe lives in his own personal world of strictly black and white morality. This gives a life that is very good but also very fragile. When reality doesn't conform to his over-simplified worldview, everything crumbles.

* ''Franchise/StarWars'': In ''Film/RevengeOfTheSith'', Anakin Skywalker slowly becomes more and more deluded that all opponents of [[BigBad Chancellor Palpatine]] are enemies of the Republic, culminating in him [[InvokedTrope declaring a]] WithUsOrAgainstUs to his former mentor. Obi-wan retorts by saying "Only Sith deal in absolutes", which might also function as this trope.
* In ''Film/TuckerAndDaleVsEvil'', Chad keeps insisting on a black and white narrative with himself as the good guy and the hillbillies as the villains. While the belief is initially fueled by a series of highly unlikely misunderstandings, he continues to cling to the belief to insane degrees once the truth becomes apparent due to some latent trauma.

* ''Literature/AvestaOfBlackAndWhite'' features perhaps one of the most extreme examples in fiction. Everything in the universe is defined by their Avesta, which is basically their moral alignment of either Good or Evil and makes someone act a certain way, with both sides locked in a ForeverWar and are fundamentally incapable of reconciling or seeing the other's side. As a result, extremist black and white thinking is not only encouraged but is basically the very framework by which the universe operates.

* Javert from ''Literature/LesMiserables'' has no room in his worldview for moral ambiguity. No matter how minor your crime was, if you break the law at all, you are evil in his eyes. He chases down Jean Valjean for ''twenty-one years'' because Valjean broke his parole. Javert's case of Black and White Insanity is so strong that when events force him to confront his worldview and his worldview creates a [[MortonsFork moral dilemma he can't solve]], he is overtaken by despair and [[spoiler:throws himself off a bridge into the Seine]].

* This is shown in ''Literature/VillainsByNecessity'', a world in which the forces of light finally won a decisive victory over darkness a hundred and fifty years ago. By the time of the story's present, the heroes of the world run about unchecked and have no qualms hunting down [[NonMaliciousMonster Non-Malicious Monsters]], brainwashing villains and robbing them of their free will, and committing genocide on AlwaysChaoticEvil races. They believe their actions are acceptable since they're "on the right side" but the [[VillainProtagonist Villain Protagonists]] of the story note that they seem more concerned with "Black and White" than "Right and Wrong."

* Police commander Howard "Bunny" Colvin from ''Series/TheWire'' bemoans how police adopting a black and white mentality and an increasing determination to never compromise or question the "War on Drugs", regardless of its obvious failings, has changed being a police officer for the worse throughout his career. In [[https://youtu.be/BA5za4VsskM?t=22s one frustrated speech]], he says that police officers are being turned into wartime soldiers, and outlines what he sees as the differences between the two. (According to him, one protects a community and the people within it, while the other kills their enemies.) He goes on to add that this has only succeeded in turning the very community that police are supposed to protect into their enemies.

Contrast BlackAndWhiteMorality (for settings where the world actually operates in a way that makes this kind of worldview completely rational). A [[DesignatedHero failed]] [[DesignatedVillain attempt]] at BlackAndWhiteMorality will make the main character come across as suffering from Black and White Insanity. Contrast GreyAndGrayInsanity for when a character's mental instability has to do with too much moral ambiguity as opposed to a black and white worldview.

* ''Manga/MyHeroAcademia'': HeroKiller Stain believes that Heroes must be possess IncorruptiblePurePureness to be "real heroes" in his eyes, and that villains that commit ''any'' type of crime must be killed swiftly, circumstances be damned. The ''only'' heroes who meet his criteria are [[BigGood All Might]] and [[TheHero Izuku Midoriya]], while he brutally slaughters and cripples other heroes for not meeting his standards. His appearance in the prequel series ''Manga/MyHeroAcademiaVigilantes'' has him brutally murder villains who have already given up and pose no further harm, and this is ''before he became a villain''. Needless to say, Stain isn't quite right in the head. Notably, at one point Stain, dismisses [[spoiler:Tenya Ilida]] as a "fake hero" because he's more focused on his RoaringRampageOfRevenge against Stain than saving an injured hero. [[spoiler:Ilida]] soon acknowledges that the VillainHasAPoint and tries to do better; Stain is ''completely'' thrown off by this, unable to comprehend that one of the "fakes" could possibly want to improve themselves.

* Nakamori Aoko in the SuperFic ''Fanfic/{{Dominoes}}'' has [[TautologicalTemplar flat-out]] [[IRejectYourReality issues]] that functionally boil down to this. Initially this manifests in childish optimism, but her simplistic moral view gains an increasingly insidious subtext as the story goes on, to the point where she implies an abuse victim and the surviving family of a murder victim (whose late victim was framed for four deaths and four dozen injuries) deserve their suffering and are unquestionably the bad guys if they stand against the ones that harmed them... because the ones who harmed them are the side she hero-worships and has joined, the International Super-Hero Association. By virtue of Aoko, her team, and the superheroes she idolizes [[TautologicalTemplar inherently]] being the good guys, the people they hurt and oppress who dare to stand up to them ''[[InsaneTrollLogic must]]'' be the bad guys.

* In the ''WesternAnimation/JackieChanAdventures''/''WesternAnimation/{{WITCH}}'' crossover ''Fanfic/{{Kage}}'', Caleb is shown to harbor a black-and-white viewpoint bordering on this trope. From the moment of first meeting [[HeroWithBadPublicity Jade]] (who's partially turned back into a Shadowkhan) when she appears by chance, he refuses to consider her to be anything but a minion of Phobos or a threat nonetheless even more adamantly than the Guardians or Elyon (due to her [[CastingAShadow shadow powers]], actions of her SuperPoweredEvilSide and [[TheMole Nerissa's]] manipulations). He also states that he'll have all the villages who supported Phobos punished, regardless of their reasoning. Jade lampshades this trope by comparing Caleb to comic book heroes who have no place for gray in their black-and-white viewpoint.
* ''Fanfic/MarinetteDupainChengsSpitePlaylist: Remix'' has Alya, who slides increasingly into this mentality over time. In her case, this stems from the notion that if [[CassandraTruth Marinette was telling the truth about]] [[ManipulativeBitch Lila]], that would mean that Alya [[WeUsedToBeFriends pushed her former BFF away]] and refused to listen to her for no good reason... and in the process, ''also'' lost Ladybug's trust and her place as Rena Rouge. [[NeverMyFault To avoid facing the idea that she made such major mistakes]], she latches onto Lila's claims that ''Marinette'' was a BitchInSheepsClothing all along, and [[BrokenPedestal so was Ladybug]]. When Adrien tries speaking out against Lila, she accuses him of being just as bad as his ChildhoodFriend [[SpoiledBrat Chloé]], [[IRejectYourReality rejecting reality]] rather than owning up to being misled.

* In ''Fanfic/WhyAmICrying'', Scootaloo has a hard time accepting the fact that [[AlphaBitch Diamond]] [[TheBully Tiara]] actually did nice things in her life, and that her kind-hearted teacher Miss Cheerilee was a cruel bully in her high school days since those facts challenge her perception that all bullies are heartless monsters who are born pure evil and are incapable of change. She gets better.

* Satoru Tojo from ''Series/KamenRiderRyuki'' is a HeroicWannabe with a habit of killing off his close acquaintances and dismissing the other Riders in the [[ThereCanOnlyBeOne Rider War]] as unworthy of being 'heroes'. Notably, it's his presence and conviction that what he is doing is right that causes protagonist Shinji Kido to seriously take into consideration that the participants of the Rider War are not simply made up of bad people wanting to do bad things and that there are a lot of gray areas to be considered.
* [[TheCynic Shijima]] [[JerkWithAHeartOfGold Gou]] from ''Series/KamenRiderDrive'' has all Roidmudes classified as pure evil and most of time he is pretty close. Enter Chase, their NobleDemon top hitman. As if that was not bad enough, Gou soon learns that [[MySisterIsOffLimits his sister]] may be in love with him. He loses a few marbles afterwards.

* ''Videogame/DragonAgeII''

* In ''VideoGame/FireEmblemThreeHouses'', This trope is a huge part of Dimitri's CharacterArc. While his moral compass can accurately distinguish what is right and just, his standards for irredeemable evil are far too strict. To him, war, self-defense, or ideology are just flimsy excuses villains use to justify murder, so there's no point in understanding or empathizing with their position. [[spoiler:Unfortunately, this outrage extends to even himself, so [[IAmAMonster he's an unforgivable bloodstained monster]] for fulfilling his princely duties and for taking joy in killing others. Only on the Azure Moon path does he come to terms with the complexity of killing and learn how to forgive both others and himself.]]
* Count [[MaliciousMisnaming Vulgar-, uh, Veger]] from ''Videogame/Jak3'' certainly qualifies. His vision of the world boils basically to: anything related to Light Eco -- good, anything related to Dark Eco -- bad. Even if the person ''unwillingly'' (though he was against it) pumped by Dark Eco is a [[DarkIsnotEvil hero]] that defeated the Metal Head leader. Predictably, the war goes to hell after Jak is banished, which probably contributed to his demotion by Ashelin.
* From ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'', [[spoiler:Atris has a simplistic sense of morality: everything is either completely good or completely evil. This caused her to turn on the Jedi Order, whom she previously saw as perfect and infallible, when their actions during the Mandalorian Wars and Jedi Civil War challenged these notions, leading her to secretly plot to recreate the Jedi Order according to her values -- where any Force-sensitive would be killed for showing even the slightest sign of turning to TheDarkSide. By the time of her final confrontation with [[PlayerCharacter the Exile]], it's clear that Atris' inability to reconcile morally grey actions has caused her to snap and turn to the Dark Side.]]

* As per the quote above, this is played with for Garrus Vakarian in ''VideoGame/MassEffect'' and ''VideoGame/MassEffect2'', both of which portray him as someone who thinks along these lines before he finally mellows out in ''VideoGame/MassEffect3''.

* N and Team Plasma from ''[[VideoGame/PokemonBlackAndWhite Pokémon]] [[MeaningfulName Black and White]]'' have this. If you're not in support of their insane CartoonishSupervillainy, then you're a cruel and abusive [[KickTheDog Lillipup-kicking]] Pokémon trainer! [[spoiler:It turns out that Team Plasma's claim to having this is merely a cover-up for their true motives -- to TakeOverTheWorld. N turns to be the true Plasma King. The only one who wants to TakeOverTheWorld is Ghetsis.]] N even all but invokes the idea by name:
--> ''"Many different values mix together, and the world becomes gray... [[ThisIsUnforgivable That is unforgivable!]] I will separate Pokémon and people, and [[TitleDrop black and white]] will be clearly distinct!"''
** In the sequel, Ghetsis and his loyalists [[spoiler:pretty much ditched their "Pokémon Liberation" facade and become full blown terrorist organization aiming for world domination]], while N is still interested in [[spoiler:freeing Pokémon]], but more specifically [[spoiler:freeing them from Poké Balls]]. As the end nears, he begins to question if people and Pokémon really can live alongside each other.

* Ishida Mitsunari in ''VideoGame/SengokuBasara''. [[LikeAGodToMe He defines 'good' as his master,]] UsefulNotes/ToyotomiHideyoshi. If you are a fellow servant of Hideyoshi, he will (grudgingly) tolerate you. If not, you are a vile sinner who will be beaten until you become a servant of Hideyoshi at best or killed in the most gruesome fashion imaginable for the 'sin' of disobedience. It doesn't help that he's quite a HorribleJudgeOfCharacter.
* ''Franchise/ShinMegamiTensei'': By the end of any of the games in the main series, both the [[ChaoticEvil Chaos]] and [[LawfulEvil Law]] factions will have degenerated into this. Don't much care for a WorldOfSilence? Then [[SophisticatedAsHell get thine ass hence]], [[YeOldeButcheredEnglish for thou art a ]] [[{{Greed}} greedy]], [[BloodKnight war-mongering]] {{Jerkass}} [[ItsAllAboutMe that placeth his own whims before the needs of thy fellow man's]]! Think that [[TheSocialDarwinist a world of social darwinism]] where MightMakesRight isn't your thing? Then [[PrecisionFStrike FUCK YOU]], you [[HolierThanThou goody-good]], [[LesCollaborateurs backstabbing]] [[ARealManIsAKiller peace-lover]]!

** In ''VisualNovel/Danganronpa2GoodbyeDespair'' you have [[spoiler:Nagito Komaeda, the Ultimate Lucky Student]], who believes hope is good and despair is bad, therefore, [[WellIntentionedExtremist all actions done in the sake of hope are good.]] The problem is their [[BlueAndOrangeMorality twisted perception of hope]] that leads them to [[spoiler:create an opportunity to murder on Chapter 1 and masterminding his own death in Chapter 5 on a ThanatosGambit to kill everybody on the island.]]
** The FanGame ''VisualNovel/DanganronpaAnother'' has Tsurugi Kinjo, the "[[TheAce Ultimate]] [[ByTheBookCop Policeman]]" whose KnightTemplar mindset gradually has him go from TheLeader to TheFriendNobodyLikes. At the very start of the game he [[LeeroyJenkins nearly gets himself killed for attacking]] [[KillerGameMaster Monokuma]], and his attempts to prevent more [[DeadlyGame deaths]] get more and more desperate as he [[WellIntentionedExtremist enacts harsh rules to try to keep everyone out of trouble]] while alienating everyone with his WithUsOrAgainstUs attitude, labeling everyone who refuses to submit to him "potential killers". He also outright refuses to empathize with any of the killers despite the impossible situation they're in, [[spoiler:such as [[BreakTheCutie labeling Taira an attempted murderer]] for not immediately coming clean about her self-defense stabbing or lashing out at Kinji for using the same TheNeedsOfTheMany logic he does. In the fourth chapter, he's even more mentally unbalanced after Kinji pointed out his [[{{hypocrite}} hypocrisy]], and when the others point out further inconsistencies with his thought process in the next trial, he stammers like a robot that's been handed a LogicBomb & [[HeroicBSOD bluescreens so badly that he passes out and gets excused from the courtroom]]. He improves somewhat in [[VisualNovel/SuperDanganronpaAnother2 the sequel]], but still retains his AllCrimesAreEqual mindset]].
* Ichijo Ayane from ''VisualNovel/FullMetalDaemonMuramasa'' is someone who firmly believes in justice and that things can easily be slotted into either good or evil and that it is her job to smite the wicked. Unfortunately for her, she is caught in a story mired with moral relativity and that there often are no easy answers. Things doesn't get any better once she meets Masamune who is just as bad in this regard leading to them having a mutual ToxicFriendInfluence on each other. The story also delves into one of the less apparent issues with this mindset in that without even realizing it, she becomes a DarkMessiah inspiring others to take up her ideals of killing those they deem evil. The story spares no expense at pointing out that there often is nothing worse than an army of people killing in the name of justice as it devalues the act of taking a life from the sin that it is to something that is morally right. [[spoiler:This is ultimateley why the main charcter Kageaki cannot side with her despite their burgeoning love for each other as he had understood the true meaning of the Law of Balance, leading to a final confrontation between the two]].

** She [[FantasticRacism despises humans]] and believes that every last one of them is nothing more than a [[HumansAreBastards cruel, hateful]] [[HumansAreTheRealMonsters monster]], although she is at least self-aware enough to realize that a few select people are capable of good deeds; for example, when Brooklyn argues that Elisa is a decent person, Demona claims that she's simply the exception that proves the rule. While Demona's tragic past ''does'' justify this belief to an extent, and she's often [[VillainHasAPoint proven right about humans]] given their horrified and violent reactions to the gargoyles, flashback episodes reveal that she has always carried extreme hatred in her heart, despite the rest of her kind realizing that humans are fundamentally different from them and need to be treated as such. It's also shown that her initial dislike of humans came from the gargoyles having to share their home with humans (who were willing to cooperate with the creatures, especially because gargoyle physiology means they can only move during the night) based on a flimsy "we were here first" argument. It also becomes increasingly clear that Demona bears the centuries-old guilt of betraying her entire clan and leaving almost all of them to die while saving herself, and thus clings to the belief that it is the fault of humans because it protects herself from having to deal with her own culpability.

This trope is ''not'' about [[JustForFun/IThoughtItMeant regarding everyone as either completely sane or completely insane]] (though that would be an example of this trope, especially if [[InsaneEqualsViolent insanity is equated to evil]]).

* Eren Yeager, the protagonist of ''Manga/AttackOnTitan''. He reacts to {{Tragic Villain}}s expressing remorse by exploding into a rage and stating they are inhuman monsters not allowed to feel emotions. When confronted by situations that are morally complicated, he tends to either freeze up or get [[UnstoppableRage angry]]. It makes his attempts to understand [[spoiler:Annie's reasons for killing people]] [[OOCIsSeriousBusiness all the more shocking]]. For whatever reason, he cannot simply dehumanize [[spoiler:Annie]] as he does to other villains. However, given how ugly and bleak the world he lives in is, it's easy to see how he would develop such a mentality, and sometimes, he's downright on the mark. The "animals disguised as humans" he killed could hardly be called anything but. They killed Mikasa's father and mother (In her case, one of the gang objected, but only because she would've fetched a good price on the slave market) and planned to sell the child Mikasa as a sex slave. [[spoiler:And, after the TimeSkip, while he manages to grow out of it and understands what his enemies are doing, it doesn't stop him from also acknowledging that his kind is being threatened by what he has considered the entire world and deciding the only path forward is to genocide everyone outside the Walls.]]
* ''Literature/AvestaOfBlackAndWhite'' features perhaps one of the most extreme examples in fiction. Everything in the universe is defined by their Avesta, which is basically their moral alignment of either Good or Evil and makes someone act a certain way, with both sides locked in a ForeverWar and are fundamentally incapable of reconciling or seeing the other's side. As a result, extremist black and white thinking is not only encouraged but is basically the very framework by which the universe operates.
** To put things into perspective, the character Alma has the unique ability to make her Avesta appear as though it belongs to the other faction allowing her to act as TheMole. But this also means that she has to be careful around her own allies as they might attack her on pure instinct even though they know intellectually that she is on their side, and that's before even getting into how hard the ability is on Alma herself psychologically. The Good vs Evil conflict is simply so fundamental of a building block of their universe that an ability like that is downright unthinkable for anyone to endure.
** One moment that really nails this down is when the demon lord [[AffablyEvil Kaikhosru]] sees through Alma's attempt to assassinate him, and instead of killing her or anything of the like, he makes her one of his mistresses and is even willing to compromise with her and show kindness. The other Good characters can't believe their ears upon hearing this and are thoroughly convinced that there must be some greater evil behind those actions. Basically, the guy acts in ways that run completely counter to everyone's understanding of morals as any kind of moral grayness is treated as straight-up BlueAndOrangeMorality in this universe.
* ''Literature/ACertainMagicalIndex'': Oriana Thomson wants all morality to be reduced to black and white. So that nobody has conflicting ideas about what is good and evil.
* ''Manga/BlackLagoon'': When [[AntiHero Revy]] finally pushes that iota too far with her [[StrawNihilist obnoxious and belligerent cynicism and nihilism]], an annoyed Fabiola goes on a blistering TheReasonYouSuckSpeech calling out how Revy isn't actually a nihilist, just a pathetic loser who has let her DarkAndTroubledPast completely consume her life and refuses to acknowledge the obvious truth that the world outside Roanapur [[WorldHalfFull is more good than bad]], because otherwise she wouldn't have an excuse to indulge her selfish, materialistic ways.
* In ''Manga/{{Claymore}}'', Priscilla believed that she and the [[TheOmniscientCouncilOfVagueness Organization]] were absolutely good because they protected Humanity from the predations of the Yoma, therefore all those who opposed them -- Yoma but also traitors like Teresa -- were evil, stemming from highly-traumatic experiences in her childhood. Her beliefs were so entrenched that she couldn't even understand ''why she wasn't winning against Teresa if she was the "bad guy"''. Once Teresa beats her she completely loses it, she throws herself at Teresa and [[spoiler:[[AndThenJohnWasAZombie awakens]], becoming the very thing she hated so much. And the series' BigBad too]].
** To complicate things further, one of the scientists at the organization has a theory about her black and white insanity: she had to develop such a twisted view of the world or she would have awoken much sooner. [[spoiler:The secret to cultivating a strong Awakening involves a contradiction of self-hate; Claymores hate Yoma, which are fueled by stress (and human entrails), but Claymores ARE part Yoma. Thus, the more they hate the Yoma and themselves, the more stress they develop, and the more inner power they can possess when they awaken. Priscilla in particular had the perceptive skill to realize that when she killed the Yoma that looked like her father, it actually ''was'' her father, then she resorted to cannibalism on her father's corpse to survive. From there, she deluded herself into thinking that she was raped by an evil Yoma, because it was ''less'' stressful on her than "your father was driven insane and wanted to kill you and eat you, and then ''you'' killed him and ate him and were driven insane'']]. Yeesh.
* In ''Anime/ConcreteRevolutioChoujinGensou'', Earth-chan subscribes to extreme black and white morality. She views any improper behavior, even anything as innocuous as a white lie, as absolutely Evil; and she cannot even understand why anyone would willingly lie. Likewise, she cannot understand someone trying but failing to live up to a moral ideal -- any failure to measure up is in her eyes a willful embrace of Evil. This attitude is shown to be at odds with a world filled with shades of grey and results in Earth-chan coming to hasty conclusions about who is in the right and taking actions that solve the immediate situation but don't actually address the underlying problem -- for instance, trying to address the problem of pollution by destroying a factory's smokestacks and then flying away with the satisfaction of a job well done, not comprehending that the factory will simply fix the smokestacks and continue as usual.

** [[spoiler:Kyousuke Munakata believed if you associated with, helped, or even sympathised with someone from Ultimate Despair, you were part of their ranks. Regardless of if you were or not, the only suitable punishment was death. This was part of the reason he hated Naegi so much (the other being he helped criminals he was supposed to execute), and the reason the ''actual'' mole hiding in the Future Foundation's ranks (his girlfriend Chisa Yukizome, who showed no outward signs of despair) went unnoticed by him for years.]]

* This tends to come up in ''Manga/DeathNote'' a lot. Light Yagami starts to shift into this as the series goes on. He sees himself and all the actions he takes as good, including killing hundreds of people. He also sees anyone who criticizes him as wrong, killing a man on live television for condemning him. The fourth Kira is this through and through (he essentially had this as a child, but couldn't quite grow out of it). Of course, the fact that Light thought "Kill every criminal" was a reasonable solution to the world's problems makes it pretty clear that he had a bit of this going on in the first place.
** Light's narrow views on morality is a big factor in his rapid JumpingOffTheSlipperySlope early on. He learns that the Death Note is a genuine ArtifactOfDoom by killing two minor criminals, and recognizes that accident or not, this was an act of evil, and he's a murderer. However, Light soon embraces the role of Kira, convincing himself that as the self-appointed arbiter of right and wrong, everything he does is completely justified, and so those initial {{Accidental Murder}}s were morally right all along.

* Kabru of ''Manga/DeliciousInDungeon'' has elements of this. He has very strict ideas about good and evil and comes to conclusions rather quickly. He heard that Laios and Falin would bring money to support their former teammates who were injured. But the former teammates went into shady business in the black market using that money. So in Kabru's eyes, Laios and Falin are responsible for perpetuating the black market on the island and are thus evil and not to be trusted. He also considers anyone who seeks to profit from the dungeon rather than focus on destroying it to be evil as well.

** This is Zamasu's primary problem. He has a very black and white view of mortals and gods. Namely, mortals are evil and need to be cleansed, while the gods are good, if not a bit [[TheGodsMustBeLazy lazy]] for not taking care of the mortals. His inability to understand that mortals can learn and grow, and the gods themselves are also [[GodIsFlawed flawed]] and need to learn from their mistakes is a point of tension between Gowasu and him. [[spoiler:He eventually jumps off the slippery slope when Goku proves that mortals can overpower gods, and decides to murder ''everyone'' in Future Trunks' timeline to create what he sees as a truly just world. Once he's cleaved in twain by Trunks, he loses what little sanity and mind he had left and tries to [[OmnicidalManiac kill everything and everyone, everywhere]].]]
** [[TheCape Toppo]] of Universe 11. His overall perception of Justice and what evil is are very skewed when you see his interactions with Goku. Even though Zen'o had already planned on destroying many of the Universes, which the Grand Priest had already told them, he calls Goku evil on the grounds that Goku has to be evil since he sparked the tournament idea. If anything, he should see Goku as good since he ensured that one of the lower level universes will be spared, and he ensured that every universe has a fair chance to try and make it so that that universe is theirs.
*** Somewhat averted in the manga where he is understanding of Goku giving them this chance (only thinking him as strange for his desire for fighting).
* ''Literature/FateApocrypha'': Atalante WouldntHurtAChild, and thus is horrified when she finds out Jack the Ripper is a little girl. To make matters worse, Jack is really an amalgamation of the souls of hundreds of unloved unborn children, driven to murder due to their hatred and rage for their lot in life. Jeanne decides the only thing that can be done is to exorcise them so they can be free from their pain and go to the afterlife. Even after Jeanne explains this, and even after Jack thanks her before passing on, Atalante condemns her and makes it her mission to kill Jeanne. As far as Atalante is concerned, even if it was a MercyKill, Jeanne killed those children, and that makes her evil. The {{Light Novel|s}} manages to explain this further: After the encounter with Jack, Atalante has a black material sticking to her arm, and it was actually a remnant of Jack that was composed of souls of unborn children that demanded vengeance rather than being happy for passing away. Jeanne missed exorcising that one, and Atalante let that material stick with her since she considered her failure to save the children something that needs punishment. The result is that [[BrainwashedAndCrazy her hatred to Jeanne got amplified to insane levels]].
* ''Manga/HunterXHunter'': Gon is a case of this mixed with OrangeAndBlueMorality. His black and white views stop him from handling the fact that some of the people he considers 'bad' have redeeming qualities or do in fact care about others. The greatest example being when he confronts Pitou, who was in the middle of healing someone. It throws him into a mental breakdown as he is unable to accept that someone he hates can do good.

* ''Anime/MartianSuccessorNadesico'' has this in the form of [[spoiler:the Jovians]]. [[spoiler:AnAesop for you, children: [[SpaceWhaleAesop don't mould the society of your]] LostColony [[SpaceWhaleAesop around an old-school Anime series that espouses]] BlackAndWhiteMorality, ''especially'' [[AntiEscapismAesop to the point that the colony forgets how reality is]].]]

* ''Anime/MobileSuitGundamSEEDDestiny'': Shinn Asuka's greatest problem is his inability to accept shades of grey. He's not exactly insane as opposed to being highly unstable as, unlike other examples of the trope, it isn't even that he can't see introspection -- it's that he just doesn't ''want'' to. By the finale though, he has definitely gone off the deep end, being willing to defend a KillSat about to destroy an entire country -- one that he's decided to be pure evil simply because they're opposing his side (the fact that he was until recently a native citizen ''actually fuels this belief''). Shinn's mess of anger issues are the root cause of this way of thinking; or rather ''lack'' of thinking. He's not an inherently bad kid, but he ''is'' too HotBlooded for his own good. Moreover, his "we're good, everyone else is bad" mentality is implied to largely self-enforced, so as to allow him to justify clinging to the vengeful anger that's kept him going all this time. This is because not only is that anger his best weapon in battle, but it's also the only thing he really has left to give him any purpose in life.
* ''Manga/MyHeroAcademia'': HeroKiller Stain believes that Heroes must be absolute IncorruptiblePurePureness to be "real heroes" in his eyes and that villains that commit ''any'' type of crime must be killed swiftly, circumstances be damned. The ''only'' heroes that meet his criteria are [[BigGood All Might]] and [[TheHero Izuku Midoriya]] respectively, while he brutally slaughters and cripples other heroes for not meeting his standards. His appearance in the prequel series ''Manga/MyHeroAcademiaVigilantes'' has him brutally murder villains that have already given up and pose no further harm, and this is ''before he became a villain''. Needless to say, Stain isn't quite right in the head.
** Notably, at one point Stain dismisses [[spoiler:Tenya Ilida]] as a "fake hero" because he's more focused on his RoaringRampageOfRevenge against Stain than saving an injured hero. [[spoiler:Ilida]] soon acknowledges that the VillainHasAPoint and tries to do better; Stain is ''completely'' thrown off by this, unable to comprehend that one of the "fakes" could possibly want to improve themselves.

** In the eyes of [[spoiler: Admiral Ryokugyu]], you're either under the thumb of the World Government or a menace to society. There is no middle ground, even if you're an upright person.

** Two-Face is sometimes portrayed as having this as the root of his multiple personality disorder. His original character concept was even more so. Originally he was actually supposed to do good deeds when the coin landed unscarred face up. This is particularly obvious in his post-''ComicBook/BatmanYearOne'' characterizations, where the "good" persona believes in fairness and the hope of goodness in people, while the "evil" side sees unfairness and cheating everywhere. To quote his revised origin:

* An early version of the Heterodyne Boys (the basis of the characters of the same name in ''Webcomic/GirlGenius'', but specifically not the same guys, according to [[WordOfGod Studio Foglio]]) has the characters traveling to an alternate universe with GreyAndGreyMorality (''ComicBook/{{Grimjack}}'' #40), where they end up killing the first guy they meet in a bar. They then proceed to conclude that he ''must'' have been evil, because where they come from, only evil people ever die. In their own universe, that is assumed to be true, but in the universe, they ended up in, that combined with their abilities essentially makes them a pair of {{Omnicidal Maniac}}s.

* ''ComicBook/{{Superman}}'';
** Subjekt-17 is essentially the living representation of Superman's nightmare of what could have happened if someone other than the Kents found him when he landed on Earth. The apparent last survivor of his race, Subjekt-17 was "raised" in isolation by a black ops government group and treated as nothing but a test project rather than a person with rights. Even after Superman is able to rescue him, Subjekt-17 appears to regard all humans as equally guilty of what he went through, content to let humanity suffer through the plans of Arion, even though his actual captors are now all dead and Superman serves as proof that not all humans are like that.

* In ''Film/TheBatman2022'' ComicBook/TheRiddler is a NotSoWellIntentionedExtremist, being a LoonyFan of ComicBook/{{Batman}} who wants to clean up crime [[SuperheroParadox like he does]] but is too AxCrazy to care about collateral damage. [[spoiler:In the climax he decides to destroy the city on the grounds that ItIsBeyondSaving and targets the new mayor to that end, in spite of the fact that she's a force for reform like he claims to be.]]
* Two-Face's condition is even worse in ''Film/BatmanForever'', where his good side, if he even has one, seems to be an excuse at best. To emphasize the point, he has two henchwomen named Sugar and Spice, a pair of attractive women who are supposed to represent his good side (Creator/DrewBarrymore) and his evil side (Debi Mazar) in very sexy ways. However, Sugar, the one who is supposed to represent his good side, is just as evil as Spice. Two-Face's actions show that rather than having a good side and an evil side, he only has the evil side but becomes obsessed with wanting the world to be fair. He only looks to commit murders but everyone gets a coin toss for a chance to be let go. Made worse by scenes showing him repeatedly flipping a coin until it comes up the way he wants it to. This makes it seem less like this trope and more like an OCD-type behavior.

* The murderer in ''Literature/AndThenThereWereNone'' suffers from this trope. They explain in a confession letter that even as a child, they were self-aware enough to realize that they [[TheSociopath lacked all emotion and capacity for empathy]], but had also been "cursed" with an extremely strong sense of right and wrong. As they grew older, they gradually became obsessed with the notion of killing someone, but this trope prevented them from simply choosing a random target--it had to be a person who had done something genuinely evil to justify the deed. The murderer then hit upon the idea of choosing TenLittleMurderVictims who had committed "untouchable" crimes--things that, while definitely deadly, the law couldn't prove or punish (such as not giving an elderly woman her medicine or berating a pregnant young woman to the point where she [[DrivenToSuicide killed herself]]). This way, the murderer got to experience the rush of killing while also administering their own twisted sense of justice. [[spoiler:Including executing himself afterward; after all, he was a murderer multiple times over.]]

* Played with in the ''Literature/{{Discworld}}'' books. Granny Weatherwax is accused of having an overly black-and-white view of the world in ''Literature/CarpeJugulum'', but as she explains to Mightily Oats, in her opinion "[[AntiHero gray's just white]] [[IDidWhatIHadToDo that's got grubby]]."

* Most of the human antagonists in ''Literature/HereticalEdge'' thing this way. The hardline faction is convinced that everything supernatural and non-human is pure evil and inimical to humanity. They're very, very wrong.

* ''Franchise/StarWarsExpandedUniverse'':
** ''[[Literature/StarWarsLostStars Lost Stars]]'': After the [[EarthShatteringKaboom destruction of his homeworld]], Alderaanian Imperial officer Nash Windrider slowly descends into this, as he doubles down on his fanatic loyalty to the Empire in order to cope. He justifies Alderaan's destruction and the deaths of his family by believing anything the Empire does is necessary for a utopian future and anyone who fights against it is absolute scum.
* ''Series/DoctorWho'':
** This trope was the reason the Seventh Doctor had to fight his counterpart from the Land of Fiction -- known as 'Dr. Who', and allegedly based on the Doctor from some of the early comics -- in the ''[[Literature/DoctorWhoNewAdventures New Adventures]]'' novel ''Head Games''; Dr. Who was only capable of seeing things in black and white, such as destroying the aliens who were threatening humans on an alien planet just because they looked like monsters (in reality they were the native population objecting to being oppressed), considering the Doctor 'evil' for destroying an alternate Earth and allowing an entire solar system to be destroyed (which the Doctor had to let happen to preserve the universe and the Web of Time respectively) and even trying to kill Queen Elizabeth II as the representative of the poor state of the modern British government

* This is Shown in ''Literature/VillainsByNecessity'', a world in which the forces of light finally won a decisive victory over darkness a hundred and fifty years ago. By the time of the story's present, the heroes of the world run about unchecked and have no qualms hunting down [[NonMaliciousMonster Non Malicious Monsters]], brainwashing villains and robbing them of their free will, and committing genocide on AlwaysChaoticEvil races. They believe their actions are acceptable since they're "on the right side" but the [[VillainProtagonist Villain Protagonists]] of the story note that they seem more concerned with "Black and White" than "Right and Wrong."
* In ''Literature/WarriorCats'', [[ByronicHero Hollyleaf]] believes that the warrior code is the utmost right and that it must be protected at all costs. [[spoiler:When she learns that her entire ''existence'' goes against Clan tradition, [[SanitySlippage she becomes justifiably insane.]] ]]

** Galad has a comparatively minor case of this; he's described as "always doing the right thing, no matter who it hurts" and has ''very'' strict ideas concerning what right and wrong entail. This leads him eventually to join [[ChurchMilitant the Children of the Light]], an organization (in)famous for this kind of thinking. [[spoiler:In the later books, he begins to lighten up, at least a little, especially after people he respects challenge his worldview and point out how even the best-intentioned person can be simply wrong, even working from the best information that they have. On the plus side, because he's now influential in the Children, his lightening up is taking the organization with him]].

* Discussed in ''Literature/TheWitchlands'', when Caden accuses Safi of this after noting that her power (she's a LivingLieDetector) lends itself for neatly arranging people into "true" and "false", stating that she's too focused on it to see the reasons behind truthfulness or falseness. Safi retorts by telling him that she can't do that because [[Series/{{House}} everybody lies]].

[[folder:Web Comics]]
* In ''Webcomic/CaptainSNES'', Max Force labels people who disagree with him about just about anything as "[[DrugsAreBad druggies]]" and attempts to shoot them down. Once he is convinced someone is a druggie, no force in the world can convince him otherwise. And when he fails to shoot [[Franchise/SuperMarioBros his target]], he comes up with [[InsaneTrollLogic insane excuses]] as to why he didn't actually miss; he was just aiming at something else.
* ''Webcomic/{{Goblins}}'': Kore the Paladin is nominally LawfulGood, a requirement maintaining his paladin status. However, he believes certain races of monsters are [[AlwaysChaoticEvil inherently evil]], and that [[VillainByProxyFallacy anyone who comes into contact with an evil creature]] becomes "infected" with evil themselves, [[RedemptionEqualsDeath which can only be cured by death]]. This includes people who merely come into contact with evil creatures, people who are kidnapped by evil creatures, and even people ''[[SympathyForTheDevil who might potentially sympathize]]'' with evil creatures. And no, [[WouldHurtAChild children are not exempt]]. And the scariest part? Kore still retains his paladin magics, which means that either the divines who guide the church agree with and/or tolerate his philosophy, or there is something very WRONG with heaven. It's also possible it's an "I believe I'm right therefore I have power" type deal. But given that it's explicit in the comic that evil is triumphing in a multiversal sense, it's more likely to be a problem with his god.
** [[spoiler:Turns out demons "cursed" him a millennium ago]]. It's not confirmed if that is the main cause of his insanity, but it probably prevented him from getting psychological help.

-->'''Lien:''' This is ridiculous! You can't just let everything be ruined and hope to fix it afterward!
-->[[spoiler:'''Serini''']]: [[TheReasonYouSuckSpeech And you can't keep knocking over the game board whenever your side starts losing!]]

* The partisan climate of the US devolving into this on both sides was the driving force behind the [[{{Dystopia}} less-than-stellar]] state of affairs in ''Webcomic/{{Remus}}''
* Glinda comes off like this in the ''Kings War'' arc of ''Webcomic/{{Roommates}}'' when she goes to war against an ''evil'', ''greedy'', ''glory-seeking'' villain who fooled people into thinking that he changed and got his hand on a magical kingdom, but villains are villains and heroes heroes, period... In her own world she might be justified, OZ is not the land of great moral ambiguity, but because the comic is a MoralityKitchenSink that ''villain'' happened to be a LawfulGood ex-HeroAntagonist, who is also the TokenGoodTeammate of the main cast. When she explained her reason boiled down to: "There are heroes and there are villains, you are a villain so you must be opposed."
* ''Webcomic/GirlGenius'': As far as Othar Tryggvassen (GENTLEMAN ADVENTURER!) is concerned, Sparks can be divided into the ones who are responsible for the deprivations Europa is under and who must therefore die, and the ones who are prepared to join him on this crusade (who must ''also'' die, but will be left to last, just before [[NoPlaceForMeThere himself]]). The amount of doublethink this requires is illustrated when Tarvek is horrified that girls with the Spark were being killed by the Geisterdamen, and Othar assumes that the fact Tarvek is not a CompleteMonster is entirely down to his influence, while at the same time reminding Tarvek (and the readers) that he would have been quite prepared to kill those girls himself.

[[folder:Web Original]]
* On the ''WebVideo/DreamSMP'', since the [[TheExile Pogtopia arc]], when his mental health took a ''[[SanitySlippage massive]]'' hit[[note]]his [[TookALevelInCynicism mental spiral]] technically [[CynicismCatalyst kick-started]] after Eret's betrayal in the L'Manburg War for Independence, but it was heavily exacerbated by Schlatt exiling him and Tommy from the country they founded [[TyrantTakesTheHelm after becoming President]][[/note]], [[FallenHero Wilbur's]] worldview has been cleanly split in half, between "heroes" and "villains". This is most clearly shown in how he treats both Dream and himself.

* ''WesternAnimation/{{Arcane}}'' has [[ManicPixieDreamGirl Jinx]]; a trauma-filled girl/woman/child that [[spoiler:turns on her sister after she discovers she's been working with an enforcer]] due to her black/white perception of allies and enemies. She also [[spoiler:turns on her adoptive father]] for this same reason.
* Near the end of ''WesternAnimation/AvatarTheLastAirbender'', especially in the finale, [[Characters/AvatarTheLastAirbenderPrincessAzula Azula]] [[SanitySlippage begins to adopt this mindset]], seeing everyone as being either completely for her or a complete traitor to her. Most notably, the end of the two-part episode "The Boiling Rock" [[spoiler:after Mai and Ty Lee turn on her]].
** Parodied when she banishes one of her twin handmaidens, convinced one is loyal and the other is treacherous, despite the fact that she can't tell them apart. They themselves couldn't decide who's supposed to leave as a result.
* ''WesternAnimation/DannyPhantom'''s first episode has Sam and Tucker on the opposing sides of a Meat vs. Veggies conflict, and put Danny in the middle:
-->'''Tucker:''' You're either with me...\\
'''Sam:''' ...or you're against him!\\
'''Both:''' SO WHOSE SIDE ARE YOU ON?!
* On ''WesternAnimation/{{Gargoyles}}'', this trope, combined with NeverMyFault, is [[BigBad Demona's]] FatalFlaw. She [[FantasticRacism despises humans]] and believes that every last one of them is nothing more than a [[HumansAreBastards cruel, hateful]] [[HumansAreTheRealMonsters monster]], although she is at least self-aware enough to realize that a few select people are capable of good deeds; for example, when Brooklyn argues that Elisa is a decent person, Demona claims that she's simply the exception that proves the rule. While Demona's tragic past ''does'' justify this belief to an extent, and she's often [[VillainHasAPoint proven right about humans]] given their horrified and violent reactions to the gargoyles, flashback episodes reveal that she has always carried extreme hatred in her heart, despite the rest of her kind realizing that humans are fundamentally different from them and need to be treated as such. It's also shown that her initial dislike of humans came from the gargoyles having to share their home with humans--who were willing to cooperate with the creatures, especially because gargoyle physiology meant they could only move during the night--based on a flimsy "we were here first" argument. It also becomes increasingly clear that Demona bears the centuries-old guilt of betraying her entire clan and leaving almost all of them to die while saving herself, and thus clings to the belief that it is the fault of humans because it protects herself from having to deal with her own culpability.
** Demona's relationship with Macbeth also proves that she suffers from this line of thinking. He was one of the few humans who she actually liked and trusted (albeit extremely reluctantly), as he showed her nothing but respect and honor for her skills as a warrior. However, when one of Macbeth's allies suggested betraying the gargoyles, Macbeth remarked that he'd think about it--even though it was clear he would ''never'' do so and only made that claim because, in his own words, "a wise king considers all options." But in Demona's eyes, anything other than a complete and violent display of loyalty to her was a sign of treachery, and so she turned on Macbeth with a hateful vengeance.
* ''WesternAnimation/GravityFalls'' has Rumble [=McSkirmish=] from "Fight Fighters". A character from a fighting game played by Dipper, he comes to the conclusion that Robbie, Dipper's romantic rival, is evil and killed Dipper's father. When Dipper admits he lied, Rumble decides that Dipper is a villain as well and beats him too.

* ''WesternAnimation/TheOwlHouse'': [[spoiler: [[Characters/TheOwlHouseEmperorBelos Belos/Philip]] operates under the assumption that all witches and demons are inherently evil and [[FinalSolution must be eradicated]], and that all humans are inherently good and must be protected, but can be corrupted through association with witches, [[MurderIsTheBestSolution at which point it's best to]] MercyKill them. He's so committed to this line of thinking that on top of the genocide of the Boiling Isles he spent 400 years planning, he murdered ''[[SiblingMurder his own brother]]'' for falling in love with a witch, and was fully ready to turn 14 year-old Luz to stone for sympathizing with witches.]]
* ''WesternAnimation/StarWarsTheBadBatch:'' Saw Garrera believes the Empire is bad (which it admittedly is) and anything he does to it is therefore good. Anyone who disagrees with him on his methods, regardless of why (like, for example, his plan being needlessly destructive) or even how minor that disagreement, is a hinderance who isn't willing to do "what's necessary". By the time of ''Film/RogueOne'', this attitude has led to Saw being a broken, paranoid wreck hiding in the wilds of Jedha, having managed to piss off any potential allies outside his small group of loyalists, and is no longer able to see that an Imperial pilot could actually defect, believing it to be a plot and having the man tortured.

** [[Characters/StevenUniverseJasper Jasper]] strongly believes in Homeworld's rigid HiveCasteSystem; every Gem is built for a purpose, and anyone who can't fulfill that purpose (such as "off-color" Gems) or won't (like the Crystal Gems and other rebels) deserves to suffer. This also applies to herself; her desperation to defeat the Crystal Gems after constantly losing to them drives her to increasingly erratic behavior, to the point [[spoiler:she ends up corrupted near the end of season 3]].

* While all the Monarchs have this to a certain degree, this is one of [[spoiler:Akane, the fifth Monarch]]'s flaws in ''VideoGame/Persona5Strikers''. After [[spoiler:her father Zenkichi]] stopped investigating her mother's murder, [[spoiler:Akane]] began to see people in two ways: law enforcers and their supporters are evil and those who fight against law enforcers (like the Phantom Thieves) are good. There is no middle ground for her. Although, prior to [[spoiler:being brainwashed to become a Monarch]], she was at least willing to listen to Makoto's advice. However, this flaw soon became magnified to extreme degrees. She rejected [[spoiler:Zenkichi]]'s legitimate reasons for backing off the case and began acting like [[spoiler:Konoe]], down to parroting the latter's goals and exact words and refused to listen to any reasoning from the Thieves due to being influenced by [[spoiler:Konoe]] without realizing it.

* Two-Face's condition is even worse in ''Film/BatmanForever'', where his good side, if he even has one, seems to be an excuse at best. To emphasize the point, he has two henchwomen named Sugar and Spice, a pair of attractive women who are supposed to represent his good side (Creator/DrewBarrymore) and his evil side (Debi Mazar) in very sexy ways. However, Sugar, the one who is supposed to represent his good side, is just as evil as Spice. Two-Face's actions show that rather than having a good side and an evil side, he only has the evil side but becomes obsessed with wanting the world to be fair. He only looks to commit murders but everyone gets a coin toss for a chance to be let go.
** Made worse by scenes showing him repeatedly flipping a coin until it comes up the way he wants it to. This makes it seem less like this trope and more like an OCD-type behavior.

* ''VideoGame/MortalKombat12023'' has Havik[[spoiler:/Dairou]], a member of the lowest caste of Seido, the Realm of Order. Brutally punished by Seido's ruling caste for a petty crime, Havik has developed the mentality of the world being divided into the oppressors, who need to be overthrown, and the oppressed, who need to be liberated wherever they realize it or not. Attempts by other characters to reason with him get nowhere because he's so adamant in his beliefs that he'd even accuses Johnny Cage of being a tyrant.

* ''VideoGame/MortalKombat12023'' has Havik[[spoiler:/Dairou]], a member of the lowest caste of Seido, the Realm of Order.

Attempts by other characters to reason with him get nowhere because he's so adamant in his beliefs that he'd even accuses Johnny Cage of being a tyrant.

* ''Franchise/MegamiTensei'': By the end of any of the games in the main series, both the [[ChaoticEvil Chaos]] and [[LawfulEvil Law]] factions will have degenerated into this. Don't much care for a WorldOfSilence? Then [[SophisticatedAsHell get thine ass hence]], [[YeOldeButcheredEnglish for thou art a ]] [[{{Greed}} greedy]], [[BloodKnight war-mongering]] {{Jerkass}} [[ItsAllAboutMe that placeth his own whims before the needs of thy fellow man's]]!
