History Main / ThisIsUnforgivable

* An unpublished story of ''WesternAnimation/ThePowerpuffGirls'', "Mojo's Day Off," had Mojo Jojo trying to relax but he is persistently interrupted by the girls who think he's responsible for some random evil in the city. In one segment, he's in an easy chair reading a murder mystery novel and comes to the part where the murderer is revealed when the girls crash through. Blossom, having read the novel herself, proceeds to spoil the denouncment.

* Wrestling/TheUndertaker's 2003 entrance theme "You're Gonna Pay"[[note]]This was the last theme of his [[FanNickname "Bikertaker"]] era before he returned to the old-school Phenom/Deadman gimmick the following year.[[/note]] is about retribution for some unspecified offense and the chorus includes the line "There's no forgiveness this time."

It is also used as a way of pointing out to the audience how evil a character is -- that they are completely BeyondRedemption. Usually the character being issued the challenge has crossed the MoralEventHorizon, or is a CompleteMonster, so the main character can freely kill them now. Though on occasion the audience still wonders [[MoralDissonance if it was really unforgivable]].

->''"The truth is, I ain’t a hero of justice or anything else like that. But anyone who tries to hurt my friends... is GONNA PAAAAAYYYYYY!"''
-->-- '''Goku''' to '''Jiren''' after the latter tries killing everyone in the Universe 7 stands, ''Anime/DragonBallSuper''

* In ''WesternAnimation/BojackHorseman'', this is the reason why Herb [[RejectedApology refuses Bojack's apology,]] even when dying at the late stages of cancer. [[EtTuBrute Bojack betraying him]] ruined Herb's life personally (Herb already had a successful life but wanted a friend to help him get through tough times... and Bojack abandoned him in his time of need.), thus refusing his satisfaction of reconciling with him.

** Zigzagged with Oliver Queen's treatment of Malcolm Merlyn brainwashes his daughter, Thea, into murdering Sara Lance, in order to instigate conflict between Oliver and Ra's al Ghul. In the finale, Oliver tells him "I will never forgive you for what you did to Sara"...and then makes him the new Ra's al Ghul, effectively '''rewarding''' him for the deed. Throughout Season 4, he never has any objection to [[EnemyMine working with]] Malcolm, thanks him for his cooperation if they ''do'' work together, comes up with excuses to not remove him as Ra's (though he eventually does), and repeatedly refuses to kill him. By the events of Season 5, though, he does state that he is through with him once he finds out that he worked together with Damien Darhk to kidnap his son, William, and only really cooperates with him to rescue his friends in the finale because, aside from Nyssa al Ghul, he has no more ally left to call.

* ''Animation/HappyHeroes'': In Season 8 episode 18, Happy S. says "Unforgivable!" to Huo Haha after he accidentally bumps into him, making him drop what they both think is an elemental a staff from a cliff. Near the end of the same episode, he says the same thing to all of Big M.'s group when they make him drop what he thinks is one of the staffs down a cliff... again.

* To the Straw Hat Pirates - Luffy most of all - dreams are SeriousBusiness. So when they are confronted to the Nightmares in ''[[https://www.fanfiction.net/s/7387687/18/Asteria-Nightmare Asteria Nightmare]]'' - a EldritchAbomination race feeding on dreams while leaving their prey a soulless husk - they immediately go on the warpath. An irate Luffy even declares he will ''kill'' the Nightmare Queen for daring to think it could steal his crewmates' ambitions, ''and he does''.
* ''Manga/Evangelion303'': Minor example. In chapter 3, after being [[OldSchoolDogFight beaten]] by [[LoveInterest Shinji]] and messing up a mission, [[FieryRedhead Asuka]] is extremely distraught and paranoid -due to several weeks of disappointments and frustrations- and she is starting to wonder if Shinji is actually trying to sabotage her. Then she angrily thinks: "This is unforgivable."

* Alluded to in the film ''Film/GungHo,'' when a shouting match between an American and his Japanese boss gets physical after the American says, "Oh yeah? Well, if you guys are so great, how come ''you'' lost the [[UsefulNotes/WorldWarII Big One]]?"
* ''Franchise/StarTrek'':
** A western equivalent appears in ''Film/StarTrekIIITheSearchForSpock'' where Kirk repeatedly kicks Klingon General Kruge, screaming "[[PunctuatedPounding I! HAVE HAD! ENOUGH! OF YOU!]]" and then kicks Kruge down a cliff.
** Picard's rant about the Borg in ''Film/StarTrekFirstContact''. "[We have fallen back] This far, and no further! The line must be drawn here!" This turns into an subversion, though, when Lily scolds him into sensibility and he decides to destroy the ship rather than fight it out.

* In the Chinese action film ''Film/FlashPoint'', the main character and detective Mah Jun, played by Donnie Yen, chases after a criminal on foot in the streets of Hong Kong. The criminal runs into a restaurant, grabs a young girl as hostage and holds her upside down by the legs. When Mah Jun catches up to him and holds him at gun point, the crook threatens to drop the girl on her head if Mah Jun doesn't drop his gun. Mah Jun complies but the criminal throws the girl [[KickTheDog forcefully aside anyway]] right outside the restaurant unto concrete ground injuring the girl. Mah Jun has a very brief HeroicBSOD and his face clearly shows a This Is Unforgivable expression followed by giving the attacking criminal a [[SuplexFinisher suplex from hell]] and then pummeling the man to to death.
* In ''Film/TheWomanInBlack'', this seemed to be the MadnessMantra of the titular woman after her child went missing, as she believed he was being deliberatel;y kept from her. Unfortunately she died before anyone learned the truth, and her vengeful ghost got stuck in an infinite loop.
* In ''Film/ConanTheBarbarian1982'', after Conan raids one of Thulsa Doom's towers and steals his treasures, he is most upset because Conan kills a giant snake guardian.
-->'''Thulsa Doom:''' You broke into my house, stole my property, murdered my servants, and my PETS! And that is what grieves me the most! You killed my snake. Thorgrim is beside himself with grief! He raised that snake from the time it was born.

* In the 2009 film ''Film/{{Cracks}}'' the Diving Team reacts like this when the find out the teacher they trusted and admired molested a pupil and allowed her to die. The school seems to turn a blind eye until the whole team symbolically turns in their sashes.
* In ''Film/HomeAlone2'', when Kevin finds out that his old nemeses, Harry and Marv, plan to rob Duncan's Toy Chest, whose proceeds are intended for a children's hospital on Christmas Day, Kevin decides that enough is enough, which sets off an even bigger DeathCourse battle than the one in the first film.
-->'''Kevin:''' ''You can mess with a lot of things...but you can't mess with kids on Christmas!''
* Similarly to how he acts in the cartoons (see "Western Animation" below), in the live-action movie of ''Film/{{Popeye}}'', the titular sailor is trying to just have some breakfast at Roughouse's when the local toughs decide to insult him. At first, Popeye stays calm and insists they apologize, but when they "apologize" by roughing up the patrons instead, he declares, "Sorry I have to do this, but enough is enough." and proceeds to clean house with all of them.

* ''Film/ANewYorkChristmasWedding'': Jenni broke off contact with Gabby when the latter had blown off their tree decorating to spend time with her boyfriend. It seems petty, but Jenni had planned to tell Gabby she loved her, with the boyfriend coming between them. She regrets it deeply later when [[spoiler:Gabby kills herself due to losing her baby]], which might have gone differently if Jenni had been there supporting her.

* [[Literature/SherlockHolmes Sherlock Holmes]], in "The Three Garridebs" when Watson is wounded, Holmes tells the idiot that shot his friend he's lucky, but if his friend had died on him, well... you can expect the knucklehead to get killed.
-->'''Holmes:''' By the Lord, it is well for you. If you had killed Watson, you would not have gotten out of this room alive.

* Invoked and subverted in ''Literature/{{Shatterpoint}}'':
-->'''[[spoiler:Depa Billaba]]:''' You can't... you can't just ''forgive'' me.\\
'''Mace Windu:''' As a member of the Council -- you're right. I can't. As your Master, I ''won't''. As your friend -- as your friend, [[spoiler:Depa]], I can forgive everything. I already have.

* ''Literature/ASongOfIceAndFire'':
** When Cersei beats the woman she thinks is Tyrion's mistress, Tyrion says "I have never liked you, Cersei, but you were my own sister, so I never did you harm. You've ended that. I will hurt you for this. I don't know how yet, but give me time. A day will come when you think yourself safe and happy, and suddenly your joy will turn to ashes in your mouth, and you'll know the debt is paid." He may not say the words, but this BadassBoast embodies the spirit of this trope ''very'' well.
** Likewise, he doesn't say the words, but Tyrion's reaction to the lies and betrayal by [[spoiler:his brother, his father and the aforementioned mistress]] is similar to this.
** Though this comes back to bite Tyrion when [[spoiler:Joffrey is poisoned on his wedding day]]; everyone assumes it was his fault, and he had nothing to do with it.
** Actually quite a few characters react this way to being betrayed. Which happens quite a lot.
* In the world of ''Literature/ABrothersPrice'', men are [[GenderRarityValue extremely rare and protected]], so when some of the heroes find one who was killed, the ones who never knew their fathers are disgusted, but the ones who did have loving fathers are horrified, furious, even panic-stricken. Most didn't know the man in question, but this is the crime that really drives them to despise those responsible.
-->"What kind of animals could do this?"
* In ''Literature/{{Divergent}}'', Will, Christina and Tris treat [[spoiler:Al this way after he assists Peter and Drew in attempting to kill Tris]]. They become more ambivalent after [[spoiler:Al kills himself]] but never speak of it again.

* ''Literature/EverythingEverything'': Madeline's reaction to finding out that [[spoiler:her mother has been lying to her her entire life, and that she isn't really deathly ill. Carla encourages her to forgive her mother, as she's clearly not right in the head and ''does'' love Madeline, but as Madeline points out, she'll ''never'' get back those eighteen years she spent unable to leave her house and interact with anyone from the outside. It's ambiguous as to whether or not Madeline will ever get over it.]]

** This was [[DeconstructedTrope deconstructed]] when Lee testified at Baltar's war crimes trial - Lee pointed out all the things members of the fleet had done that should have resulted in imprisonment (or execution) that had been "forgiven" by either Admiral Adama or the President, and that the only reason Baltar's crimes were unforgivable and deserved his execution was that [[InsufferableGenius no one liked him]].

** In season 8, after a BrainwashedAndCrazy Angel [[spoiler:kills Giles]], Buffy refuses to forgive him. Buffy is also blamed for the world's magic being lost and even the other slayers tell her what she did was unforgivable, despite the fact that Buffy had no choice but to destroy the source of Earth's magic to save the world.

** In "[[Recap/DoctorWhoS35E10FaceTheRaven Face the Raven]]", the immortal Ashildr is involved in a plot that results in the unexpected [[spoiler:death of the Doctor's companion, Clara]]. The Doctor threatens Ashildr, "I will '''end you''' and everything you love" before Clara talks him down. After the deed is done, the Doctor makes it clear to Ashildr that forgiveness is not on the table. In the SeasonFinale [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]] two episodes later, in which the Doctor has become a DrivenToMadness WoobieDestroyerOfWorlds in the wake of said disaster and a stint in a torture chamber, their paths cross again, and [[spoiler:while he doesn't forgive her onscreen, he does allow her to follow him into the second TARDIS rather than leave her to die at the end of time]]. The same episode suggests that with regards to her collaborators' role in the aforementioned plot AND their work as architects of [[spoiler:the Last Great Time War]], he sees [[spoiler:Rassilon and his underlings on the High Council]] as unworthy of forgiveness, and [[spoiler:exiles them from Gallifrey after bloodlessly overthrowing them]]. Keep in mind that this particular Doctor, the Twelfth, is one of the '''''most forgiving''''' incarnations. His unwillingness to forgive Ashildr is personal: he's the one who saved her from death's door in a way that made her functionally immortal to begin with and, as centuries passed, believed in her goodness even when she did not and worked to protect her — and she chose to betray him (and hurt others as the hanging judge mayor of the trap street) for all that. As for her collaborators, [[spoiler:they '''were''' partially responsible for the worst war the universe ever saw, one '''he''' brought to an end for them (and it was only because of Clara that he spared them when he was doing so)... and look how they repaid him, all out of fear of a prophecy]], and they are '''not''' the sort of people likely to atone and apologize anyway.

** Earlier in the series, episode 20 sees Drive flip out at the Roidmude Medic about the way she has taken over Chase's former job as the Roidmude Grim Reaper[[note]]Chase would simply reset the Roidmude's core, allowing it to take a fresh start. Medic, on the other hand, would make sure Roidmudes that were failing their missions were terminated.[[/note]] Drive outright said that compared to Chase, Medic was a devil.

** And again with Mordred in season 5 when Merlin [[spoiler:reveals Mordred's plan to escape with Kara resulting in the latter's death.]]
* In ''Series/OnceUponATime'', Regina blames Snow White for the death of her lover and being forced into a crappy ArrangedMarriage with Snow's father, the king. Never mind it was [[EvilMatriarch Regina's own mummy dearest]] who actually killed the lover - and killed the former queen - and forced the marriage; Snow gets blamed because she was manipulated by Regina's mother into telling her about Regina's lover for well-meaning reasons (at the age of ten). Snow White flees Regina's murder attempts and becomes a forest-dwelling bandit. Regina takes the throne and [[GodSaveUsFromTheQueen rules about as well as you'd expect]] from someone termed 'the Evil Queen'. When Regina ends up in a peasant woman disguise and actually meets Snow again, Snow admits she pities Regina and would be willing to forgive her... until she discovers that her stepmother just executed an ''entire village'' down to the last man, woman and child for the mere "crime" of giving Snow a night's shelter, which Snow herself declares unforgivable.

* In ''WebComic/SequentialArt'', the Quinten story arc begins with Kat and Scarlet going clothes shopping, and Kat being subsequently kidnapped by Quinten employees who mistook her for Scarlet, [[spoiler:an escaped {{WetwareCPU}} component]]. The next comic shows Art and Pip coming back from a movie to find [[ItsAllMyFault Scarlet on the porch, bawling her eyes out from guilt]]. After she explains how [[spoiler:she escaped from Quinten when the AI she was analyzing tried to kill her in the garbage incinerator]], [[BreakTheCutie she cries some more]], saying that its her fault that Kat was taken, and that she's scared and doesn't know what to do. In what is probably the only display of genuine affection he has shown to Scarlet thus far, Pip says that Quinten must pay for making Scarlet cry.

* In ''FanFic/DungeonKeeperAmi'', what amounts to this happens during the [[http://addventure.bast-enterprises.de/246220.html invasion of Dreadfog Island]], when [[spoiler:Empress Mercury learns that the undead priests of the Crowned Death have plucked out the eyes of eight thousand captive innocents they intend to sacrifice -- including children -- so that they couldn't cause trouble]]. Ami's response?
-->''Cold rage simmered in Ami's heart as her bright crimson gaze focused on the fog-covered island, a dark stain against the setting sun. Crowned Death and his minons would pay, she promised herself. Her armoured gauntlets, balled tightly into fists, groaned as her fleet charged onwards into the blood-red sunset. They. Would. Pay.''

* In season 1 of ''WesternAnimation/WinxClub'', when Bloom is taking her simulator test, her rabbit Kiko secretely joins her. When the Trix sabotage the test to see if Bloom has the Dragon Flame, they try to get her angry. They eventually manage to get this reaction out of her when they shoot Kiko into lava. Bloom goes crazy and easily drives the Trix away, but the Trix do confirm that she has the Dragon Flame. Bloom and Kiko turned out okay, since it was mostly just a simulation.
* ''WesternAnimation/TransformersAnimated'': "Wasp... forgive... Bumblebot... [[spoiler:...but ''Waspinator'' NEVER FORGIVE!!!"]]

* Many ''ComicStrip/{{Popeye}}'' cartoons find the sailor, pushed to the limit, saying, "That's all I can stands, I can't stands no more!" or "I've had enough, and enough is too much!"
* In ''WesternAnimation/TheAvengersEarthsMightiestHeroes'', Hawkeye's "You're dead to me!" is a particularly harsh variation reserved for a former friend, Black Widow.

* The title character of ''WesternAnimation/DanVs'' does this in every episode. Once he wants revenge on someone (or something), almost nothing will convince him to do otherwise.
* In ''WesternAnimation/BojackHorseman'', this is the reason why Herb [[RejectedApology refuses Bojack's apology,]] even when dying at the late stages of cancer. [[EtTuBrute Bojack betraying him]] ruined Herb's life personally (Herb already had a successful life but wanted a friend to help him get through tough times... and Bojack abandoned him in his time of need.), thus refusing his satisfaction of reconciling with him.
-->'''Herb:''' I'm not gonna give you closure. You don't get that. You have to live with the shitty thing you did for the rest of your life. You have to know that it's never, ''ever'' going to be okay! I'm dying! I'm not gonna feel better! And I'm not gonna be your prop so ''you'' can feel better! Do you know what it was like for me? I had nobody. Everybody left! I knew all those showbiz phonies would turn on me, sure. [[EtTuBrute But]] ''[[EtTuBrute you]]''? I don't care about the job! I did fine! I had a good life, but what I needed then was... a friend. And you abandoned me. [[RejectedApology And I will]] ''[[RejectedApology never]]'' [[RejectedApology forgive you for that.]] [[GetOut Now get the]] [[PrecisionFStrike fuck]] out of my house!
* ''WesternAnimation/ElenaOfAvalor'': [[spoiler:After Esteban's betrayal is revealed, Elena and their grandmother Luisa tell him [[RejectedApology to screw off with his apologies]] and excuses because his actions got Elena and Isabel's parents King Raul and Queen Lucia killed. Esteban desperately wants to redeem himself, but Elena eventually breaks it to him that he's BeyondRedemption, especially after [[DiggingYourselfDeeper he broke out of prison with a bunch of dangerous villains that he then teams up with to avoid taking his sentence]]. On the other hand, their grandfather Francisco [[EasilyForgiven forgives him]] because he believes he has changed while his other cousin Isabel isn't sure what to think of him yet. [[BrokenPedestal Everyone else views him with contempt]]. Elena's anger with Esteban is bad enough that she initially tries to {{unperson}} him, but she comes to terms that she still loves him and that's part of why she'll never forgive him for hurting her and everyone else so badly. On the other hand, Elena's parents, after their deaths, forgive him]].
* ''WesternAnimation/{{Kaeloo}}'': In the season 3 premiere, Planet Smileyland gets destroyed and any person has the ability to recreate it the way they want. The gang sends Quack Quack to recreate it exactly the way it was, but it ends up becoming a planet where a) everything is made of yogurt, including everyone's precious personal possessions, and b) Stumpy's girlfriend, Ursula, becomes an {{unperson}} since Quack Quack doesn't know her. Kaeloo says she will never forgive Quack Quack. Subverted since he manages to fix everything and Kaeloo tells him that his actions have been ForgivenButNotForgotten.

** Earlier in the series, episode 20 sees Drive flip out at the Roidmude Medic about the way she has taken over Chase's former job as the Roidmude Grim Reaper[note]Chase would simply reset the Roidmude's core, allowing it to take a fresh start. Medic, on the other hand, would make sure Roidmudes that were failing their missions were terminated.[/note] Drive outright said that compared to Chase, Medic was a devil.

* At the end of ''Film/DawnOfThePlanetOfTheApes'', [[spoiler: Caesar finds himself unable to forgive nor forget Koba's genocidal rampage against the humans that restarted the ape-human war and made it impossible for the apes to ever live in peace as well as violating the ApeShallNotKillApe rule by trying to kill him and murdering Ash and several other apes. Ultimately, Caesar drops Koba to his death telling him "[[YouMonster You are not ape!]]"]]

** Faith actually tries to get Willow to give her the whole "you can still be a good guy" speech, instead getting Willow telling her she's way past forgiveness. At least part of this is because she had kidnapped and tied up Willow though. Ironically, Willow becomes one of the few people who actually could later understand what Faith was going through, having gone evil and killed someone only to be brought back by someone showing caring and kindness when she didn't deserve it.

!!Examples

[[folder:Anime and Manga]]
* In ''Manga/AzumangaDaioh'', Tomo pulls off the "decayed" version of this on Yomi, whose "unforgivable" crime is... successfully using a vending machine after it ate Tomo's money and eating curry without spilling any. Leads to a moment when Tomo chases Yomi around trying to whack her with a cafeteria tray, and hits Yukari instead.
* Used by TheIngenue Eve Genoard near the end of the ''LightNovel/{{Baccano}}'' light novel ''Drugs and Dominoes'', after she learns that [[spoiler:Gustavo]] [[YouKilledMyFather killed her father and brother]]. She almost shoots him, but is stopped by Luck Gandor, who [[ShootTheDog does the honors in her stead]].
* PlayedForLaughs during an episode of ''Manga/{{Beelzebub}}''. After a demon world plant eats the...thing he brought to life from a demon world book, Beel goes all fiery mad, and in his baby gibberish declares "I will never forgive you for this!"...and gets swatted aside. He is just a baby after all.
* Villain example: Rosine, the BigBad of ''Manga/{{Berserk}}'''s Lost Children arc, uses this line on Guts after he [[spoiler:destroys the tree that she has been using to make her creepy little pseudo-elves out of the children she's kidnapped]], which has the effect of ''supremely'' pissing Rosine off -- badly enough in fact, that she decides to [[spoiler:[[OneWingedAngel transform into her]] ''[[OneWingedAngel true]]'' [[OneWingedAngel Apostle form, a really creepy insect-like monster]]]].
** Another villain example from ''Berserk'': when Nosferatu Zodd's duel with Guts is interrupted, he roars this at the interlopers. This guy takes the WorthyOpponent BloodKnight dynamic ''really'' seriously.
** An actual (anti) heroic example comes from Guts in volume 17, where he says something to the same effect. After getting a WhatTheHellHero lecture handed to him, Guts rethinks how he dealt with avenging the Hawks [[spoiler:after Griffith betrayed and sacrificed them during the Eclipse]] and that since he technically played a role in the group's downfall, he didn't have a right to avenge them... however, for what Griffith did to Casca during the Eclipse [[spoiler:in which he viciously raped her in front of Guts and drove her insane as a result]], Guts said that he would ''never'' forgive Griffith.
* Ashley of ''Manga/BetrayalKnowsMyName'' yells this in episode 12 because Hotsuma ruined her clothes during their fight.
* ''Manga/BlackCat'': In the anime Train says this after Creed kills Saya.
* ''Manga/{{Bleach}}'':
** When Rukia is being arrested, she tells Ichigo that if he comes after her, she will never forgive him. After some [[ComplainingAboutRescuesTheyDontLike complaining]], however, she comes to terms with the idea of him helping her.
** One of the earliest was when Orihime destroys the Numb Chandelier, after first declaring "I will never forgive those who hurt Tatsuki!"
** After Captain Komamura yells this at [[spoiler:Tousen and Aizen]], he proceeds to immediately bring out his Bankai and asskicking ensues. ''His'' ass, that is.
** Captain Hitsugaya utters this at [[spoiler:Aizen]] a few scenes earlier, in response to [[spoiler:Aizen stabbing Hinamori]]. Hitsugaya then gets worked.
** Ishida utilizes it during an internal monologue as he's facing down Mayuri Kurotsuchi. It's [[{{foreshadowing}} implied]] at the time that he might one day end up eating his words as the internal monologue also indicates his SuperMode response to how unforgivable he views Mayuri's behaviour to be has not met the requirements he was giving for activating the power.
** Mayuri had one of his own against Szayel Aporro Grantz. Szayel claimed to be perfect and Mayuri derided him for it, as a man of science would be rendered obsolete by perfection.
** In the English dub of anime episode 144, one of these occurs when Ichigo, Chad and Uryu Ishida fight two Arrancar in Aizen's palace in Hueco Mundo. Ishida says that the less human Arrancar look, the less intelligent they are. One of the Arrancar does ''not'' take this well and tells Ishida so. In a subversion, Ishida proceeds to destroy him in the ensuing fight.
** Charlotte Cuuhlhourne repeatedly screams this after Yumichika [[TraumaticHaircut damages his hair]].
** Barragan...
*** Says this multiple times after all his [[EliteMooks Fraccion]] have been killed. It is unclear if he is angry at the captains for killing them or if he is angry at the fraccion for making him get off his ass and participate in the fight.
*** Says it twice in a row after he survives the Vizard Hachigen trapping him inside a kido barrier and Captain Soifon blasting him with her bankai.
** Similarly, Captain Yamamoto says this to the vice-captains when they need his help to destroy Allon.
*** He earlier tells Kyoraku and Ukitake that while he's willing to allow his other men to track down and kill Renji for saving Rukia from her execution, their dishonoring their position as captains is far more severe and forces him to deal with them personally. He also seems to take it personally that ''they'' were the ones to sabotage the execution, if his boasting about the pair is anything to go by; it's 'unforgivable' not just as his subordinates but as his [[LikeASonToMe favourite students]].
** Ichigo says it to Kumoi (who's holding Lurichiyo hostage) in anime episode 186.
** After Tousen outlines his grievance against Kenpachi for killing the previous captain of Squad 11, Kenpachi asks if Tousen hates him, Tousen responds in the dub by saying that "(he) simply find(s him) UNFORGIVABLE!" (and says that Kenpachi is "[[MoralEventHorizon beyond redemption]]" in the English version of the manga) before releasing his bankai.
** {{Subverted}} in anime episode 198. During the fight between Espada #7 (Zommari Rureaux) and Captain Byakuya Kuchiki, Rureaux says it to Kuchiki after Kuchiki uses his bankai on him. Captain Kuchiki then proceeds to effortlessly deflect Rureaux's special attack and destroy him with a single blow.
** Anime episode 204. Princess Lurichiyo and her servitor Kenryu have a falling out over Kasumioji clan policies. To heal the rift between them, Ichigo and friends pretend that Kenryu is going to commit suicide in shame. Lurichiyo falls for it, but Kenryu blurts out the truth and Lurichiyo tells Ichigo and the others that what they did was unforgivable.
** Anime episode 243. Yumichika says it to his zanpakuto's manifested spirit Ruri-iro Kujaku while fighting him.
** Anime episode 289. Arrancar #0 Yammy Riyalgo says it to Captains Byakuya Kuchiki and Kenpachi Zaraki while he's fighting them. He then activates his Resurrección form.
** Anime episode 326. Captain Hitsugaya and Reigei!Momo are fighting, with Hitsugaya getting severely hurt because he can't fight back. When the real Momo Hinamori intervenes, she tells Reigei!Momo that hurting Hitsugaya is unforgivable. It turns out that the real Momo Hinamori is in fact [[spoiler:another Reigei!Momo pretending to be the real one]].
* A lot of this flies back and forth when most of the cast of ''Manga/BokuraNoKiseki'' regains their PastLifeMemories. To be specific, they are all the reincarnations of people in two groups: the original inhabitants of a castle in Zerestria that was invaded and destroyed by a country that was ''supposed'' to be its ally, and guests living in the castle who were from said invading country, Moswick. In particular, Meguro, the reincarnation of a squire of Zerestria, freaks out and tries to kill Nishina, who was a knight of Moswick. [[spoiler:Teshimano and Harusumi talk him out of it.]]
* Possibly one of the more ''terrifying'' examples occurs in the manga adaptation of ''VideoGame/BreathOfFireIV''. Right after seeing a village of child-summoners murdered, Ryu utters a "This Is Unforgivable" as he unleashes '''''[[UnstoppableRage THE KAISER DRAGON]]''''' (for those unfamiliar with ''Franchise/BreathOfFire'', think "nigh-unstoppable {{Kaiju}}-esque Dragon Of Mass Destruction"). It takes a CoolDownHug from Nina (whom, for the first time in her life, is scared out of her wits by a dragon)--and this is after the Kaiser Dragon has not only decimated a LEGION but ''bored a hole through a '''mountain''' via its BreathWeapon''.
* ''Anime/CarriedByTheWindTsukikageRan'': A CatchPhrase of the honor-loving titular character is "Utterly Inexcusable!" which she tends to see a lot in the acts committed by others which prompt her to take action against them.
* A rather odd example occurs in ''LightNovel/ACertainMagicalIndex'' when Touma says this to the villain of the Daihasei Festival arc, Oriana Thompson, who is involved in a plot to brainwash the city. It's not the possibility of mass mind control that really upsets him, though, it's that her actions are interfering with the festival that's going on. Yeah, Touma can be a bit [[SkewedPriorities strange]].
* When Chrono and Rosette discover Aion's plan in ''Manga/ChronoCrusade'' (right after [[spoiler:destroying much of New York City in the process of executing it]]), they fly into a rage and shout "Aion, we will never forgive you!"
* Priscilla from ''Manga/{{Claymore}}''. She goes into a CRISIS of "Unforgivable", much like a Shinji's "must not run away", before actually going Berserk. The worst is that it was completely unjustified, and that her immature, self-righteous, ignorant attitude makes her do the heart-wrenching thing that is the basis for all the Claymore plot.
** Her repetition of "Unforgivable" is more of a MadnessMantra, as it shows her ''absolute'' belief in the rules, and marks the beginning of her mental breakdown.
** Clare from the same manga also utters this, which she mixes with "[[IllKillYou I will kill you]]" [[spoiler:during her fight with Rigaldo]].
* Tamaki from ''Anime/CodeGeass'', despite being TheFool of the team, definitely gives vibes of this when [[spoiler:he assumes the Britannians planned to lure the Black Knights and all the Japanese into a kill zone disguised as the Special Zone.]]
* ''Manga/ACruelGodReigns'': This is Ian's opinion of Natasha staying silent about his father abusing Jeremy.
* ''Anime/CowboyBebop'' episode 22 "Cowboy Funk". During their confrontation on top of the ruined building Spike says "I will never forgive you" to Cowboy Andy, who's been interfering with his efforts to capture Teddy Bomber throughout the episode.
* ''Anime/CuteHighEarthDefenseClubLove'': The super-pretentious Chevalier Aurite hands out not one, but ''two'' ''yurusenais'' to the Battle Lovers, when the two opposed teams of [[MagicalGirl Magical Boys]] confront each other. It's ''combined'' with a [[GivingSomeoneThePointerFinger Pointer Finger]]. [[AntiClimax Then the bad guys just walk off]]. This is [[LampshadeHanging lampshaded]]:
-->'''Battle Lover Epinard:''' They introduced themselves then left...\\
'''Battle Lover Cerulean:''' Lucky for us. You can't talk to guys like that anyway.
* ''Manga/DGrayMan'':
** Someone once managed to get [[AllLovingHero Allen]] angry enough to say this. EPIC asskicking ensued, but even so he was rather hopelessly outnumbered, and it took [[spoiler:some timely assistance from the generals]] to take out all the {{mooks}}. [[spoiler:Then things went downhill...]]
** Occurs in episode 56 from Allen to Tyki.
** When Skin Bolic goes OneWingedAngel against Yu, he begins chanting "Never forgive" [[MadnessMantra over and over]].
* Used to great effect in ''Manga/DeathNote'' [[spoiler:as Matsuda gives Light his much-deserved punishment]].
-->'''Matsuda:''' I'll ''kill'' him! I'LL KILL HIM! HE HAS TO DIIIIIIIIE!
** To illustrate, Light uses a form of this to his [[{{Mook}} girlfriend]] Misa at one point, when he's telling her not to screw up the task he's giving her.
* ''Manga/DeliciousInDungeon'': Although he doesn't say it aloud, [[spoiler:Shuro goes from friendly to ready to kill Laios after learning Team Touden used the dark arts to revive Falin. After he explains the potential consequences for everyone involved, it's kind of hard to blame him. Though he admitted that in the same situation, he probably would have done the same thing. It's mostly Laios' blithe attitude about it that infuriates him]].
* A favourite line in the Japanese version of ''Anime/DigimonDataSquad'''s Masaru Daimon.
** Typically, dubs don't carry this phrase over, substituting it for something that sounds more badass to the Western ear, but this dub actually uses this phrase frequently. And since [[spoiler:Kurata]] is the biggest monster in the Digi-verse (yes, even Myotismon has met his match) everyone gets a chance to say it more than a few times. The dub of ''Anime/DigimonTamers,'' on the other hand, used it once, by [[TheHero Takato]] and [[DarkIsNotEvil Guilmon]] as [[KnightInShiningArmor Gallantmon]]. It was [[LampshadeHanging Lampshaded]] by [[BadassBiker Beelzemon]], who said "You can't ''forgive'' me? I don't recall ever ''asking'' for forgiveness!" And then the fight was on. It's not {{Narm}}ful like the Data Squad version because Gallantmon didn't dramatically yell it, but stated it in a more matter-of-fact "this is why I must kill you" manner, befitting a literal KnightInShiningArmor.
*** Despite ''Digimon'' being a kids show, Gallantmon was willing to execute Beelzemon, and would have gone through with it were it not for the fact that said enemy's biggest victim, Juri/Jeri, asked for him to be spared.
*** Also (bonus points for {{Irony}}) not only Takato and Guilmon, but the rest of the heroes ''including'' Jeri ''do'' forgive him after his HeelFaceTurn. Beelzemon, however, [[BeAllMySinsRemembered never quite manages to forgive himself]], and says this trope word-for-word.
---->'''Beelzemon:''' What I did... is beyond forgiveness. I don't need anyone to tell me that.
** In the third-to-last episode of ''Anime/DigimonFrontier'', [[spoiler:Lucemon, in his Chaos Mode, is having his NearVillainVictory moment of being about to finish off the [=DigiDestined=] with his Ultimate Sacrifice attack. Loweemon gets in the way and sacrifices himself against said attack, and Lucemon absorbs Koichi's data after the deliverance of both darkness spirits to Koji by him following that. Takuya does not take well to what Lucemon did to Koichi AT ALL. "How could you?! Lucemon, you've gone too far!!!!" Cue the appearance of Susanoomon afterwards]].
*** Prior to that, the [=DigiDestined=] were in their final battle against Crusadermon and Dynasmon. Interestingly, up until that point, every other time they fought them, the Royal Knights had been kicking their sorry asses [[spoiler:until Lucemon was finally resurrected]]. One episode later, after [[spoiler:Lucemon's revival]]? Crusadermon [[spoiler:seems to have been having trouble having faith in Lucemon lately]], which leads her to get knocked down easily by [=MagnaGarurumon=], to Dynasmon's horror. Enraged, Dynasmon vows to make the children pay for the "ruinous wound" as he called it, and prepares to use his Breath of Wyvern attack... only to proceed to get his butt handed to him on a plate by [=EmperorGreymon=] just as easily.
** ''Anime/DigimonAdventure02'' had a [[TearJerker quite]] [[NightmareFuel horrific]] instance this from [[IneffectualSympatheticVillain Mummymon]] in the penultimate episode: after watching [=MaloMyotismon=] ''brutally'' torture and kill Arukenimon [[ForcedToWatch while he and the heroes watch in horror]], Mummymon ''flips out'' and attacks [=MaloMyotismon=], trying to avenge her.
--->'''Mummymon:''' "You've taken away my Arukenimon, ''and now I'm going to make you PAY for what you did to her!''"
** In ''Anime/DigimonAdventure'', a similar scenario is what [[spoiler:activates Mimi's crest and makes Togemon evolve to Lilimon]]. In the original dub, at least.
** Lighter example in ''[[Anime/DigimonAdventure Adventure]]'' as well: Yamato says to Joe that "above all" he can't forgive a guy who covers himself in an all men's bathhouse, while the latter is wearing a towel. There's goofy music in the background, but the immediate ''"ichiban yurusenee"'' drop shows he means very SeriousBusiness. Mayhem ensues.
** Mimi of ''Anime/DigimonAdventure2020'' declared that she would never forgive Andromon for [[spoiler:killing the Guardromon who had been helping the Chosen Children.]] Naturally, this resulted in [[spoiler:Togemon evolving into Lilimon and completely defeating Andromon.]]
* Goku of ''Anime/DragonBallZ'' generally delivers this line to villains who went too far with [[KickTheDog Kicking The Dog]], but tends to forget about it before the fight is even over (both Vegeta and Frieza were allowed to leave alive).
** The Frieza example was more of a case of CruelMercy on Goku's part (considering Frieza was HalfTheManHeUsedToBe at this point courtesy of his own energy disc), followed by blasting him to hell when Frieza made the mistake of trying to blast Goku InTheBack as he was trying to leave (though Frieza did get better).
** Taken to the next level in the last fight of the Cell Games arc. Cell went out of his way to make sure Gohan was well and truly pissed off, finally killing the GentleGiant Android 16, to let out Gohan's whole power. [[GoneHorriblyRight It]] [[BewareTheNiceOnes worked]].
** Also happened earlier in ''Manga/DragonBall'' when Tambourine killed Krillin. Unlike Goku's later "This Is Unforgivable" moments, Goku actually kills Tambourine purely for revenge.
*** This results in Piccolo subsequently invoking the trope.
* ''Anime/DragonBallSuper'':
** Goku Black explains his origin story. [[spoiler:He's a version of Zamasu from an alternate timeline, who used the Super Dragon Balls to swap bodies with that version of Goku. He then murdered Goku in his old body and then murdered his wife Chi Chi and son Goten.]] Upon hearing this, Goku explodes with power and rage, roars that he will never forgive him, then seriously tries to kill Black.
** Goku screams this and attacks furiously when [[spoiler:during their tournament fight, Jiren spitefully attempts to kill Goku's friends who were in the audience with an energy blast]].
* [[spoiler:Izaya]] from ''LightNovel/{{Durarara}}'' mumbles this during a flashback of middle school. [[spoiler:He's referring to Nakura who stabbed Shinra who is his only friend. Let's just say, Nakura was screwed the minute he stabbed Shinra by accident because of who his real target was. And 7-10 years later, Izaya extracts his revenge in the cruelest way possible.]]
** Just about everything Izaya does pisses Shizuo off to no end, but two particular incidents made the latter really want to kill the former. One: [[spoiler:Manipulating a little girl into a failed attempt at killing Shizuo, which put a [[OOCisSeriesBusiness cheerful]] [[{{Unsmile}} smile]] on his face.]] and two: [[spoiler: Izaya almost getting Vorona killed in his attempt to kill him and bragging about it. Shizuo [[TranquilFury calmly]] tells Izaya "Goodbye."]]
* Kouta, from ''Manga/ElfenLied'', is understandably miffed when he realizes that [[spoiler:the young woman he's been helping since the first episode is the same one that he watched kill his father and sister years ago]]. And the EnfanteTerrible Mariko considers her fellow lab project Nana having friends to be cause enough for this.
* Every member of ''Manga/FairyTail'' will make sure that anyone who would disrespect their guild or hurt their friends will get no less than what they deserve.
* As one of the oldest examples in {{Shonen}} anime (in fact, the show that kicked off the Shonen fighting genre), Kenshiro of ''Manga/FistOfTheNorthStar'' often only broke his [[TheStoic understated]] manner of speech to deliver this line, or a line to this effect, to some bad guy who went too far in [[KickTheDog Kicking The Dog]], often followed with something about how there [[LudicrousGibs wouldn't even be bones left]] [[PrepareToDie after he was done with the offending party]]. After saying it, he ''would'' kill the person he said that to. ''Even if'' DefeatMeansFriendship and the antagonist turned out to be noble all along.
* ''Anime/{{FLCL}}''. In episode "Brittle Bullet" Naota's father walks into Naota's room and catches him and Haruko accidentally kissing. He is interested in Haruko himself, so he tells Naota that he can't forgive him and challenges him to a duel for Haruko's affections.
* {{Subverted}} in the ''Manga/FruitsBasket'' manga. Kyo thinks that [[spoiler:Tohru's mother]] said this to him [[spoiler:as she was dying after her fatal accident, and that she died hating him for not saving her]]. However, a flashback near the end of the series reveals that what she was trying to say was "If you don't pay your bill, I won't forgive you," an effort to remind him of [[spoiler:the promise he made to look out for Tohru]].
** When Kagura almost lets slip to Tohru about Kyo's true form, Kyo [[HandGagging covers her mouth]] and says "If you utter another word, I'll never forgive you!". In response, Kagura yanks Kyo's arm behind him and says "Oh you won't forgive me will you?!"
* In ''Manga/FullmetalAlchemist'', Winry finds out that [[spoiler:Scar]] is responsible for the murder of her parents, [[spoiler:she immediately picks up a nearby gun and points it towards him, only stopped by Edward]]. Later on, she [[spoiler:runs into him and cooperates with him, but makes it clear that she does not forgive him for what's he done and only helping him because it is what her parents would have done]].
* Chichiri of ''Manga/FushigiYuugi'', who rarely gets angry, furiously unloads this statement on a group of warriors who are about to disgrace an ally's sacrifice. Wisely, they back down.
** Suboshi's brother was [[spoiler:seemingly killed by the Suzaku Seven (but really, it was Tomo), and kills Tamahome's family in revenge. Tamahome's response is to go [[UnstoppableRage apeshit]] and nearly kills Suboshi in their first fight.]]
* This was practically the CatchPhrase of Cure White from ''Anime/FutariWaPrettyCure''. Cue asskicking of the MonsterOfTheWeek. Sometimes Cure Black said it at the same time, which is the leading cause of death among ''Anime/PrettyCure'' villains.
** Then, in ''Anime/SuitePrettyCure'', it becomes the pre-TransformationSequence [[PreAsskickingOneLiner one-liner]] CatchPhrase for the lead duo.
* In chapter 51 of ''Manga/FutureDiary'' this is written on [[{{Yandere}} Yuno's]] diary. [[spoiler:"Amano was kissed by Akise. That Akise... I won't forgive him...!"]]
* In episode 5 of ''Anime/{{Gankutsuou}}'' Maximilien screams this during his fight with Albert.
* In Episode 13 of ''WesternAnimation/GIJoeSigma6'', after having heavily damaged his ability to assume battle mode by blowing up his Power Stone in front of him, Duke battles it out with COBRA Commander in a one-on-one duel without weapons to have him prove how tough he is. After taking a few blows from the villain, he shouts out, "I've had it with you!" before fighting back and besting him with some more punches.
-->'''Duke:''' [[AndThisIsFor That was for the team...]] ''[punches and sends COBRA Commander sliding on his feet towards the edge]'' ...and THAT was for '''YOUR PAYBACK!'''
* [[KidHero Weed]] from ''Anime/GingaDensetsuWeed'' says that he never forgives someone who abuses or kills other dogs just for the killer to save their own hides.
* ''Manga/HanaukyoMaidTeam La Verite'' episode 9. After Lemon, Marron, and Melon speak rudely to Captain Konoe Tsurugi, Konoe's lieutenant Yashima Sanae tells them "Speaking so rudely to captain...unforgivable!" She then chases them away.
* Although the intentions aren't carried over between meetings, this is often Hayate of ''Manga/HayateTheCombatButler'''s manner when Nagi is threatened. Gilbert is frequently the target, and clearly frightened of the consequences of his actions, though not repentant not to try again at a later date.
* In the 7th OVA of ''Manga/{{Hellsing}}'' Seras screams this repeatedly at Zorin when the latter insults the dead Pip, calling him an 'insect'. [[UnstoppableRage And then she goes]] ''[[UnstoppableRage utterly ballistic]]''.
* ''LightNovel/HighSchoolDxD'': PlayedForLaughs in the Issei Hyoudou vs Vali Lucifer fight. Azazel claims that Vali will use his Divine Dividing ability to shrink the breasts of the girls around them. An enraged Issei roars that he will never forgive Vali for that, gains a massive power boost, and beats the shit out of him. Vali is completely dumbfounded by this, his tone of voice in the rest of the battle making it clear that he cannot ''believe'' what he's hearing.
* Any time this is uttered in ''VisualNovel/HigurashiWhenTheyCry'' (or "I'm sorry," if it's said ''sotto voce''), someone is going to get murdered. [[ColdBloodedTorture If they're lucky]].
** Higurashi Kira Episode 2 (the MagicalGirl episode) had Satoko declaring that she would not forgive [[NebulousEvilOrganization Tokyo Magika]] for hurting her Nii-nii. Later, Oyashiro Rika and Trap Satoko declared payback time before moving on to finish off Nail Ripper and send [[spoiler: [[BigBad Miyo Takano]]]] flying.
* When Jonathan Joestar meets Dio Brando in ''Manga/JoJosBizarreAdventure'', the ''very'' first thing the latter does is literally [[KickTheDog kick Jonathan's dog Danny]]. Jonathan responds with the trope name, though he doesn't do anything to follow up on it, at least not for a while; it might have been less of a big deal in this context, seeing as he's not Japanese. Regardless, this little scene paints their relationship for the rest of their lives. It went over so well that it eventually became his default taunt in ''VideoGame/JoJosBizarreAdventureAllStarBattle''.
-->'''Jonathan:''' ''[enraged]'' What was that for?! HOW DARE YOU!
** Later, after a long string of torment from Dio, what really set Jonathan off was Dio stealing the SacredFirstKiss of Erina, Jonathan's LoveInterest. This prompts an enraged Jonathan to race home to give Dio a thrashing for this injustice.
** It is rather ironic that Jonathan is so quick to declare this at first; later on he's easily the most forgiving Joestar in the series, by a very wide margin. [[spoiler:He even forgives Dio for killing him on his honeymoon, along with ''everything else'' he did, and tells him he thinks of him as a friend as they sink to the bottom of the ocean.]]
** In Part 2: Jonathan's grandson, Joseph Joestar lays into a mafia gangster and his mook for one: mocking his TokenBlackFriend Smokey in public, and two: thoughtlessly upsetting Joseph's Granny Erina with news of the supposed death of his HonoraryUncle Speedwagon. He would later gundown a vampiric Straizo for the murder.
*** Despite having never met him, Joseph has clear respect for his deceased grandfather, which makes his hatred for Dio all the more apparent. Not only did Dio [[spoiler:[[HeroKiller kill Jonathan]] at the end of part 1, he decapitates his head, and steals the body of his rival for his own. When he told the story to his grandson Jotaro in the beginning of Part 3, it was clear as day Joseph was ''pissed''.]]
--->'''Old Joseph:''' This son of a bitch took over his body!!!
** In Part 3: Stardust Crusaders, the protagonist and Joseph's grandson, Jotaro Kujo, states that while he isn't a nice guy, he won't tolerate hurting innocent people. The then BrainwashedAndCrazy Kakyoin learns what happens when you press such a BerserkButton the hard way when Hierophant Green injures the school nurse.
*** One of the antagonists of Part 3, Steely Dan kills Enyaba, who was [[UndyingLoyalty wholeheartedly loyal]] to Dio, holds Joseph hostage with his Stand, the Lovers, and subjects Jotaro to one humiliating act after another. After finally being cornered, Dan [[VillainsWantMercy begs for mercy]], but Jotaro tells it straight to his face that he'll never forgive him, and [[ExtremeMeleeRevenge savagely beats Dan]] with Star Platinum.
*** [[spoiler:In the climactic battle of Part 3, Jotaro has Dio at his mercy after unlocking the ability to stop time. Unlike his ancestor Jonathan, Jotaro doesn't forgive Dio for all that he's done (which includes killing Kakyoin and Joseph, the latter of whom later gets better), but he won't kill him while he's down, because it would leave a bad taste in his mouth. It's only after Dio shortly recovers from his legs being broken and tries one last desperate attack that Jotaro finally finishes him off.]]
--->'''Jotaro:''' [[spoiler:There's only one reason why you lost, Dio. There's just one simple answer. You really pissed me off.]]
** Jean-Pierre Polnareff vowed to his deceased sister that he would kill "the man with two right hands", who brutally raped and murdered her. He succeeds, [[spoiler:especially after J.Geil and Hol Horse seemingly kill Avdol. Later on, he would avenge the deaths of Avdol (for real this time) and Iggy by killing Vanilla Ice]].
** This is pretty much Josuke Higashitaka's [[BerserkButton typical reaction]] to anyone who insults his trademark hairstyle. [[spoiler:When he was young, he was mysteriously struck down with an intense fever (which was actually due to Dio's influence) and his mother, Tomoko had to drive him to the hospital. Unfortunately, there was a heavy blizzard that day, and Tomoko couldn't drive through the thick snow. But then, as young Josuke's life hung in the balance, a young man with a pompadour appeared and offered to help push Tomoko's car through the snow, and mysteriously vanished after he succeeded. Josuke was forever grateful to this teenager, and styled his hair after him in respect.]] Any insult to his hair [[spoiler:is seen as an insult to the young man who saved his life]], and he will react with violence, as seen when he maims a rude upperclassman with his Stand Crazy Diamond, and he beats Rohan to within an inch of his life after he insults it in their rather one sided fight.
--->'''Josuke:''' I won't let anyone get away with making fun of my hair, no matter who it is.
** Angelo, the StarterVillain for Part 4, kills Josuke's maternal grandfather, Ryohei Higashikata, as payback for arresting him years before the events of Part 4 began. Josuke's response isn't to kill him or send him back to jail, but to fuse the bastard in stone, [[AndIMustScream trapping Angelo in a]] FateWorseThanDeath.
** Josuke and Okuyasu feel this way about [[spoiler:the murder of their friend Shigechi at the hands of [[SerialKiller Yoshikage Kira]]. They, and the rest of the Morioh Warriors, vow to avenge him and the other murder victims by bringing Kira down]].
** The Joestars are well known for not just their determination and ability to withstand pain, but also their compassion and unwillingness to forgive evil. Giorno Giovanna, [[spoiler:the son of DIO conceived through Jonathan Joestar's body]], exemplifies this in his own way. His goal is to take control of the Italian mafia gang, Passione, and reform it to be a force for good, to protect innocent people, and he won't spare anyone who harms the innocent. One example of this is when he kills Polpo by making him unwittingly eat his own gun, using Gold Experience to turn it into a banana, which ended with Polpo involuntarily shooting himself in the mouth. Prior to this, Polpo's Stand, Black Sabbath killed an old janitor, and Polpo showed no remorse or care for anyone who got killed because of his Stand's action, due to his belief that God is willing to forgive murder when someone insults you. Giorno takes this to heart when he commits the murder of Polpo.
--->'''Giorno:''' So an act of disrespect is justification for murder in your book, huh? I see now. You taught me a very important lesson... which is handy since you disrespected the life of that innocent old man. I took the liberty of changing one of your guns into your favorite snack. ''(turns to show a disgusted frown)'' [[PrepareToDie It's your last meal, Polpo. Hope you enjoy it.]]
** Bruno Bucciarati already had a sour opinion of Passione circulating drugs throughout Italy[[note]]due to what happened to his father years prior[[/note]], but once he learns first-hand that [[spoiler:the head of the organization plans to murder his own daughter (who had no idea he even existed), for his purely selfish ends, Bucciarati is instantly inspired to betray the Boss in order to protect Trish]].
--->'''Bucciarati''': Right now the Boss is... [[spoiler:The most repulsive form of evil is to exploit innocent people who don't know anything, and to use others merely for their own gain! A father did ''this'' to his innocent daughter, all to cover his own ass?! This is unforgivable! You have once again betrayed my heart!]]
* Kagome from ''Manga/InuYasha'' has this reaction when ManipulativeBastard [[BigBad Naraku]] stages an EvilPlan designed to turn the TrueCompanions against Sango and/or corrupt her by forcing her to kill her mind-controlled little brother and/or kill them all by luring them into a castle full of poisonous miasma. She locates him by the fragments of the Shikon no Tama he has, and fires a purifying arrow at him. [[HolyHandGrenade Which blows through a building outer wall, dissipates the toxic miasma,]] ''[[HolyHandGrenade and]]'' [[HolyHandGrenade blows off his arm.]] He is so stunned he just stands there while she fires a ''second'' arrow at him, which reduces him to [[NighInvulnerability a head]]. After that he flees, and it's a long time before he dares face her again. She's actually so pissed off that the mere ''beginning'' of her "I won't forgive you"-like declaration features a whole page and follows ''for several pages''.

* This is practically King Dedede's {{Catchphrase}} in ''Anime/KirbyRightBackAtYa''.
** Then there's that moment in the episode "Sweet and Sour Puss" when a monster called Togeira possesses him, taking away his ability to get angry and causing him to act kind and calm towards others even through all the beatings everyone gives him. Much later, after the King has been pounded and smacked around enough, Togeira, having been storing his anger from within him while everyone was beating on him, stores enough of his anger to unleash it all in one big mega-attack that has Dedede exploding into a massively firey rage that scares everyone and scream at the top of his lungs, "Now it's payback time!" Dedede eventually goes back to his normal self after he slips on a banana peel, therefore knocking Togeira right out of his own head.
* ''Manga/TheLegendOfZelda'':
** The manga adaptations of the ''Zelda'' series done by Akira Himekawa seem to love this trope. For example, in the ''VideoGame/TheLegendOfZeldaALinkToThePast'' manga, after Agahnim sacrifices Zelda in front of Link and sends her to the Dark World imprisoned inside a crystal, Link shouts out, "Agahnim, I'll never forgive you!" before absorbing his magic with the Master Sword, leaving Agahnim shocked in a "ThisCannotBe" manner and sending the magic right back at him.
** Also, in the ''Manga/TheLegendOfZeldaOcarinaOfTime'' manga, after Link is forced to kill his old friend, Volvagia, in order to free him from Ganondorf's control and awaken Darunia as the Sage of Fire, he calmly declares this trope to the BigBad himself.
--->'''Darunia:''' I understand how you feel. Stay here and cool your head. If your emotions erupt you will never defeat Ganondorf.\\
'''Link:''' You're right, Darunia. But I... I will never forgive Ganondorf.
* ''Anime/MazingerZ'':
** Whenever Kouji Kabuto said this sentence, you knew he was REAL angry, and someone was going to be summarily trashed in the near future. A good example was in the manga, after he learnt [[BigBad Dr. Hell]] had created a weapon that was able to nullify gravity... and had tested it on an ''entire city''. Another two memorable instances happened in the ''Anime/{{Mazinkaiser}}'' movie (Mazinkaiser vs Great General of Darkness: at the beginning, after Lori and Loru's [[spoiler:HeroicSacrifice]], and at the end, right before he [[spoiler:absolutely destroys the Mykene empire army]]:
--->'''Kouji:''' Because of you... Many people have died... THAT IS UNFORGIVABLE! [[https://www.youtube.com/watch?v=qiZwGqhTP5I]]
** This sentence was also used fairly often by Baron Ashura (to Kouji and his friends after being defeated) and Dr. Hell (to Ashura after his servant botched still another operation).
** Tetsuya Tsurugi of ''Anime/GreatMazinger'' and Duke Fleed of ''Anime/UFORoboGrendizer'' also followed in Kouji's footsteps.
* In the first season of ''Anime/MermaidMelodyPichiPichiPitch'', [[MagicIdolSinger the heroines]] say this most of (if not all) the time to their enemies (be it the Dark Lovers or the Black Beauty Sisters) for whatever it is that they did that terrorized the seas or the people, be it making a theme park only to destroy it, chase down a boy who assaulted them with a water hose and retaliate by attacking, or even planning to force-feed chocolates to girls (which would turn the Mermaid Princesses to mermaid form).
* In the finale of ''Anime/MobileFighterGGundam'', Domon says this to [[spoiler:Major Ulube]], who has been behind all the crap Domon had to go through.
-->'''Domon:''' [[spoiler:You piece of filth! My dad! My mom! My brother! Schwarz! My master! You've taken them all from me! And now Rain! Ulube... ]] You'll pay for this. There's no way I'll ever forgive you!
* The fifth episode of ''Anime/MobileSuitGundam00'' Season 2 has the A-Laws [[spoiler:attacking the Cataron base (that contains war orphans as well as the members of Cataron itself), bombing the base, taking out all their mobile suits with ease and then letting loose little robotic shooting machines of death, the Automatons, as cleanup. When Lyle, secret member of Cataron that he is, sees the carnage, he goes GunsAkimbo on the robots and then turns on the A-Laws pilot above him, shouting "I'll never forgive you! I'll never forgive you, A-Laws!"]]
* ''Anime/MobileSuitGundamSEED'' has Kira Yamato and Athrun Zala go through this with each other, appropriately named the Cycle of Hate, when they kill each other's respective friend in battle. [[spoiler:The cycle only breaks when Athrun seemingly kills Kira himself. Kira actually survives and is nursed back to health by Lacus, Athrun's ex-fianceé. Ultimately subverted because as time passes, the complicating politics of the situation make each realize there are bigger things to worry about. They, Lacus, and Cagali actually end up uniting [[TakeAThirdOption on a third front]].]]
** [[SilkHidingSteel Lacus herself]] notably threatens this early on in a {{Foreshadowing}} moment for both her and the enigmatic ZAFT Commander Le Creuset. He internally questions her timing at pulling this out, but says "I understand", and backs down.
* ''Anime/MobileSuitGundamAGE'' follows suit when Flit returns from his battle against [[spoiler:Desil]]. As he's prepared to enter the battlefield one last time, he declares that he will never forgive the UE for [[spoiler:killing Yurin]].
** This case was an excellent example of how much impact the phrase has lost over the years. When Flit says it, the viewers didn't give it much thought... and then were very surprised to see that, after the TimeSkip, Flit ''meant'' what he'd said, and had dedicated his life to exterminating the UE, at any cost, regardless of how ruthless he had to be to do it.
--->'''Prime Minister:''' Commander Asuno! If you do this, any hope of compromise will be lost! This war will continue until one side is completely wiped out!\\
'''Flit Asuno:''' Yes, I know. That was my intention from the beginning.
** Kio also deliver this phrase to [[{{Jerkass}} Zanald]] after [[KickTheDog killing Deen]], with [[SuperMode FX Burst]].
* In ''Anime/MyOtome'', while Arika fights Tomoe, the reveals that she was responsible for all of the [[MurderTheHypotenuse thi]][[AttemptedRape ngs]] Miya [[TakingTheHeat took the heat and got expelled for]]. Arika only responds with shock until Tomoe, while mentioning her responsibility in the acid drop that injured Arika's friend Erstin, [[spoiler:[[SpeakIllOfTheDead expresses pleasure regarding Erstin's death]] some time afterward]], prompting Arika to respond with this phrase.
* Used in ''Manga/{{Naruto}}'' during the Retrieve Sasuke arc. Jirobo made the mistake of insulting Shikamaru, then fighting Choji, who considers him his best friend. He shouts the trope and wins the fight. Seriously, don't ever insult Choji's friends.
** Tsunade says this to the six paths of Pain after they level Konoha.
** Naruto himself is also clearly thinking this [[spoiler:during the fight with Pain. However, the Fourth happens to partially disagree because he believes what Pain said about the cycle of hatred. Naruto settles on a middle ground: he won't forgive Pain, but he won't kill him either, [[RedemptionEqualsDeath which ends up paying off]] [[LaserGuidedKarma very well]]]].
** In the "Fire Temple" Filler arc, Sora tells Kazuma he won't forgive him if he [[BerserkButton insults his father again]]. However, Kazuma's response is "You won't forgive me? So what?!"
** Naruto's fight with Gaara. Towards the end of the fight, he screams "I've HAD IT with you!" (in the anime) and head butts him. Later on, when both are too weak to even get up, he attempts to crawl ON HIS CHIN and defeat Gaara.
** Naruto says this to Haku after he "kills" Sasuke.
** Kakashi has this reaction to Kabuto [[DueToTheDead raising the dead and forcing them to fight for him]]. Specifically, Kabuto raised some of Kakashi's [[WorthyOpponent Worthy Opponents]], who had finally come to peace at the moment of their deaths. And Kabuto took away that peace by [[MoralEventHorizon yanking them back into the world of the living as undead slave soldiers]].
* Negi from ''Manga/NegimaMagisterNegiMagi'' uses it the first time he confronts Fate Averruncus, this is a subversion, since Fate way out-classes Negi. Later [[OldMaster Evangeline]], however, [[IAmNotLeftHanded kicks much butt]].
** Chachamaru uses it facing down a magical wild beast.
* Haruka in ''Anime/{{Noein}}'' once she really starts getting pissed at the villain. It took the entire series for her to get to this point, and she had been accepting of nearly everyone else's [[Main/{{Jerkass}} Jerkassness]]
* ''Manga/OnePiece'':
** Luffy angrily battles Zoro because he had slaughtered most of the villagers of an island (early on into the Baroque Works arc), who had given the Straw Hats plenty of food earlier on (pointed out by Luffy looking like an impossibly fat slob at the moment). Luffy was unaware that they were in fact bounty hunters. He even actually utters "Unforgivable" before the battle rages higher.
** In fact, any time Luffy angrily shouts something about TrueCompanions (at a villain, that is), it means this (as abusing one's TrueCompanions or threatening his own is the one thing that will make Luffy go mad). After this, [[CurbStompBattle asskicking ensues]].
** Robin gets like this whenever someone destroys history in front of her (ruins, artifacts, etc.). In the Skypiea arc, the poor bastard who pressed her BerserkButton ended up begging for forgiveness. Robin's response? "No." *CRACK*
** In the sixth movie, after Luffy sees [[spoiler:his entire crew get eaten by a ManEatingPlant partnered to]] the BigBad, he invokes this several times…only to be powerless against said Big Bad. It gets an echo later: after [[spoiler:said ManEatingPlant is killed, and along with it the PlantPeople that were created from the Big Bad's memories of his deceased friends and crewmates that he used in order to pretend that they were still alive.]] Realizing that the illusions were broken, the Big Bad turns on the one who killed his plant while invoking this trope, only to be stopped by Luffy, who ''kills him''. Yes, you read that right; it really was beyond any possibility of forgiveness.
** Dueling examples from Iceberg and Franky. Iceberg declares he can't forgive Franky for building the weapons that were used to frame their father figure, Tom. Franky in turn cannot forgive Iceberg for building ships for the World Government, who did the framing. Both are subversions. Iceberg states that even if he can't forgive Franky, he is still happy Frankey isn't dead and eventually gets over his anger. Franky later realizes that Iceberg making connections with the government prevented them from doing the same to him as they did with Tom.
** After learning Doflamingo's extent of crimes, [[spoiler: such as enslaving the native dwarves, turning dissenters to toys, and launching a successful FalseFlagOperation against King Riku which not only defamed him, but also doomed his grandchild Rebecca into a hated teenager, pragmatic characters like Franky and ''Robin'', who would normally give the mission the most priority, declare this in TranquilFury, working then to destroy Doflamingo's regime.]]
** Two actions that Sanji will never forgive, let alone do, is waste food or let someone go hungry; he almost starved to death once as a child, and knows it is ''not'' pleasant. One of the few times he tried punching a foe (he almost never uses his hands in a fight) was against someone who used food as weapons and armor, clearly never intending to eat it.
*** Being the ChivalrousPervert he is, he will also never forgive anyone who [[WouldHitAGirl raises their hand against an innocent woman]]. [[spoiler:So when his asshole brother Niji does everything mentioned above, you can simply imagine Sanji's utter '''''FURY'''''.]]
* In an episode of ''Manga/OuranHighSchoolHostClub'' Tamaki says "Unforgivable!" when eavesdropping on a moment between Haruhi and Hikaru.
* ''Manga/PeachGirl'': Momo says this when a trio of girls who are in love with Kairi destroy a necklace Toji gave her because they are jealous of her for getting Kairi's attention.
* In ''Anime/PeterPanNoBouken'' Hook says this to a ''giant sea creature'' (no, not the crocodile), which might make uninitiated anime fans watching the subbed version wonder why a giant sea creature cares whether Hook forgives it or not.
* Towards the end of ''Anime/{{Pokemon}}: Black and White'' Season 1, after [[spoiler:Meowth betrays Ash and the group, Pikachu becomes extremely furious with Meowth for even doing it, and decided that the final straw. He freed the group's Pokemon to assist in the escape, and when Team Rocket retreats, Pikachu has to be held back by Ash]].
* Tatewaki Kunō says this ('Yurusen!' actually) in ''Manga/RanmaOneHalf'' during his first fight with Ranma, after he insults Akane. Cue ass-kicking - Kunō's.
* Yomiko of ''Anime/ReadOrDie'' says this as she breaks down and sobs in an incredibly TearJerker scene in the {{OVA}} after [[spoiler:the Nancy clone [[ImpaledWithExtremePrejudice impales the original Nancy with her arm]]]].
* ''Manga/Reborn2004'' Tsuna says this when he is enraged by Byakuran [[spoiler:for triggering events that led to Uni's self-sacrifice, or self-imposed death]]. There is a good reason why that chapter was labled "The Last Blow."
** And again in chapter 339 to Daemon Spade.
* ''Manga/RosarioPlusVampire'': In chapter 41 of the second manga season Kurumu says "...won't forgive. I won't forgive you if you hurt Tsukune!"
** Several members of Tsukune's UnwantedHarem threaten this at times, even to [[spoiler:Moka]] when it looked like she might have been about to kill him.
** In chapter 50 Tsukune says this to Miyabi because he invaded Mizore's village and planted a ForcefulKiss on her.
** The only time [[spoiler:Tsukune]] speaks when he's entered his super-powerful ghoul mode is to say [[TranquilFury "Unforgivable. You even hurt my friends. I won't let you off."]]
* ''Anime/SailorMoon'':
** Used often in Sailor Moon's InTheNameOfTheMoon speech.
** Other Senshi also use it as well, specially Rei/Mars ([[spoiler:a MonsterOfTheWeek destroys her song sheets she worked so hard to write so she could be in her SchoolFestival]]) and Ami/Mercury ([[spoiler:another MonsterOfTheWeek uses ''babies'' as hostages, not allowing Moon and the others to attack her]]) in the R season.
** A particularly effective one of these was uttered by Makoto/Jupiter, just before destroying Falion with her Supreme Thunder attack.
** A baddie also uses this; namely, Nehellenia in the penultimate story arc in the anime, when Galaxia tricks her into unleashing a nightmare by repeatedly muttering "Unforgivable" until a mirror appears from her heart. She then shatters it, unleashing a curse onto Tokyo.
* Fumio of ''Manga/SaitamaChainsawShoujo'' breaks into a MadnessMantra version of this, just before [[{{Yandere}} snapping due to being dumped]] by her boyfriend. And then [[ChainsawGood we all]] [[GirlWithPsychoWeapon know what]] [[AxCrazy she does next]].
* In ''Manga/ShamanKing'', Yoh immediately goes ballistic on Faust after the latter has just tortured Manta in front of him, even to the point of stating to him in his rage quite a few times that he will never forgive the latter for hurting his friend before he ends up running out of Furyoku as a result of losing control of himself. Then again, not very many things manage to piss off such a generally cheerful and relaxed protagonist that way.
** A villainous example that is played for laughs with Boris, one of Hao's followers. The minute Horohoro points out that his teammate, Kouji Yamada (or Damayaji however you want to refer to him), looks more like a vampire than him, Boris immediately flips out, breaks down crying and screams "Unforgivable!" at the thought of being "compared to a miserable creature" in a humiliating way, [[DisproportionateRetribution and proceeds to kill his own teammate to destroy any confusion]], afterwards blaming Team Yoh for the humiliation. He later screams this again when Ryu manages to punch him in the face.
** In the 2001 anime, after Hao eats his brother Yoh's spirit (after which he attempts to digest it and therefore cause him to become one with him), Yoh's friends fly into a rage and make several futile attempts to attack him out of unforgiveness towards him. Even his fiance Anna says that she will never forgive him. Things settle down a lot when Manta helps them defeat his Shikigamis, though, and more so when Yoh regains his spirit to the relief of all of his friends, and Anna welcomes him back.
--->'''Tao Len:''' ...You took my friend away and YOU'RE GOING TO PAY!!
* In Episode 9 of ''Anime/SonicX'': How dare you, Eggman! You destroyed Amy's lucky bracelet that she made for Sonic to protect him when he goes in the water, despite his fear of it. And she reacted with the line of "[[ThisCannotBe I don't believe it!]]" Not only did it make her cry a few seconds afterwards, but shortly after, she flew into a rage with fire burning in her pupils. You hit Amy's BerserkButton and you didn't even know it. Now she's REALLY PISSED at you, screaming at the top of her lungs, "Now you're gonna PAY!!!", which takes you by surprise. Once she charges at you and one of three of your current [[MonsterOfTheWeek Robots Of The Week]], Serpenter, shouting to you both "Don't mess with me!" along the way, and proceeds to kick its ass before going after you next, that's where you realize that you never should have made her this pissed off at you and that you're completely screwed. Cue OhCrap.
** Also, in the original edit, this is Sonic's final line at the end of the finale of Season 3, obviously declared against Eggman. It was replaced in the dub by another line in the form of "Life never stays slow around here for long! Thank goodness! Watch out, Eggman, I'm comin' at ya full speed!"
* In ''Manga/SoulEater'', Death the Kid is as likely to use this in reference to anyone affecting his beloved symmetry as he is to any villain who likes to gather human souls for themselves and/or insult Shinigami-sama.
** More dramatically, [[BumblingDad Spirit]] tells this to [[AbusiveParent Medusa]] when she say she plans to abandon Crona.
* In the ''Anime/SteelAngelKurumi'' series, Kurumi says this whenever Nakahito, or Nako gets hurt.
* In ''Manga/SukebanDeka'', "Saki's" catchphrase is "Omaera, Yurusansezore!" (You Won't Be Forgiven!)
* Tenchi's mother in TheMovie, ''Anime/TenchiMuyo in Love,'' utters this. Yeah, up to this point, Achika was the OrdinaryHighSchoolStudent, and Kain was a SealedEvilInACan that nothing else in the universe could defeat. [[LetsGetDangerous Doesn't matter]].
* Even the otherwise lighthearted ''Anime/TengenToppaGurrenLagann'' has an example: post-TimeSkip, Yoko [[spoiler:picks up teaching in an elementary school as job]], hiding her real identity. When two rogue Ganmen show up and start wrecking the place, she gets angry. But when they threaten the life of one of her [[spoiler:students]] (a little girl), she utters the line as she goes ''[[BerserkButton batshit fucking mad]]'' and breaks out the hidden armory. [[BadassTeacher Asskicking ensues]].
* ''Manga/TokyoMewMew'' does this really well, with the Mew Mews using this against the aliens and their Chimera at random times, either before or after transforming.
** [[CatGirl Ichigo/Zoey]] even uses this trope as quite a BadassBoast towards a monster attacking Tokyo in her dream in the beginning of an early episode.
--->'''Ichigo:''' You're a wicked monster and you've terrorized this city for the last time. Now you'll pay!
* Fujiwara no Mokou in the ''Franchise/TouhouProject'' manga ''Inaba of the Moon and Inaba of the Earth'' likes using this trope when it comes to her bitter rival Kaguya. Face it, she just hates her so much because of the humiliation she gave her father.
* This phrase is used a few times in ''Anime/TransformersSuperGodMasterforce''; for example, by Minerva when the Decepticons [[KickTheDog kill a little girl's puppy]], and by Ranger when they seriously injure his horse.
* [[CreepyChild Maria]] of ''VisualNovel/UminekoWhenTheyCry'' yells this repeatedly in episode 22 before taking revenge on her [[AbusiveParents abusive mother]].
** Earlier, Battler was angered by [[WickedWitch Beatrice]] having gleefully laughed about [[spoiler:Eva-Beatrice killing and reviving Rosa and Maria over and over again]], so much so that he decided he wouldn't accept "that bitch" as his opponent. He told Virgilia that she could call her student if she wanted to, but that didn't mean he would forgive her. A disappointed Virgilia told Beato to try being more encouraging if she was to be forgiven by him and accepted as his opponent.
* Judai of ''Anime/YuGiOhGX'' is fond of this phrase when ItsPersonal, i.e. finding out his mentor is a TreacherousAdvisor (working for the BigBad, okay, not too nice — but betraying his trust = unforgivable).
** This is also a common utterance for the heroes in the original ''Anime/YuGiOh'' (not the Toei one). Offending Yami on a moral/emotional level is not good for your health.
*** Happens so often in the original manga its practically Yami's catchphrase. What's especially hilarious is when he does it several times to the same person.
*** Becomes kind of ironic when villains who are defeated are often redeemed (more often in the anime). Yami can be surprisingly forgiving for his character type, as long as the villain ceases villainous activity. Exceptions include the Thief Bakura, who never reformed and represented the ultimate enemy.
* In ''Manga/YuYuHakusho'' seasonal BigBad Sensui forces the heroes to play a video game made real by a [[PsychicPowers pyschic child]], who is playing as the game's BigBad. As long as the heroes keep playing they can't die but if they win the game the kid dies, something Sensui conveniently forgot to tell his child follower. The team is reluctant to does this; but in the end one of them, [[NobleDemon Kurama]], does the deed. Afterwards, Kurama doesn't utter this line but you can ''definitely tell'' he's thinking it; both by the expression on his face and his actions later on.
** Yusuke also declares this to Toguro once he [[spoiler:kills Genkai]]. But it's made very convincing by the [[TranquilFury cold, bitter delivery]].
[[/folder]]

[[folder:Video Games]]
* This is Lenneth Valkyrie's big proclamation in ''VideoGame/ValkyrieProfile''. She had been impassive up to now.
* ''Franchise/{{Disgaea}}'':
** Vyers from ''VideoGame/{{Disgaea|HourOfDarkness}}'' uses these exact words, twice, when Laharl, his would-be [[TheRival rival]], unflatteringly refers to him as irrelevant and redubs him "[[UnknownRival Mid-Boss]]". He loses the ensuing battle, and the insulting moniker sticks with him [[GoldfishPoopGang for the rest of the game]].
** Laharl says the same thing later on when someone messes up his hair. [[spoiler:This is a clue that Mid-Boss is actually his father in disguise.]]
** In ''VideoGame/{{Disgaea 5|AllianceOfVengeance}}'', Usalia makes it a very, very, ''very'' damning point to Majorita that she'll never forgive her for [[spoiler:torturing and zombifying her parents]], '''ever.''' This mindset remains even [[spoiler:in the post-game, where Majorita joins the Rebel Army and Usalia still has nothing but hatred for the girl who did all those things to her and Toto Bunny.]]
* Kim Kaphwan from the ''VideoGame/FatalFury'' and ''VideoGame/TheKingOfFighters'' games has a variation of this. Whenever he fights a criminal (or simply evil, or perceived as evil) opponent, he [[GivingSomeoneThePointerFinger points his finger at them]] and says "Aku wa yurusan!" ("Evil cannot be forgiven!"). Starting with the NESTS saga (King of Fighters 1999-2002), he even complements the pointing with GlowingEyesOfDoom.
** His disciple May-Lee actually does something similar in King of Fighters 2001, Franchise/KamenRider-ish pose and all.
* Declared by Tails after [[spoiler:Eggman appears to have killed Sonic]] in ''VideoGame/{{Sonic Adventure 2}}''. He seems to largely forget about it when things settle down, though.
* Used by Mickey in ''VideoGame/KingdomHeartsII'' after Goofy has been (apparently) killed, triggering his costume change along the way and making room for what may be the most epic battle sequences in this game.
** Just the fact that Mickey (THE [[MickeyMouse Mickey]]) says [[TranquilFury "They'll pay for this,"]] is enough to put chills in your spine.
* The original ''VideoGame/{{Suikoden|I}}'':
** When done with an already-defeated villain, this turns out to be the ''wrong'' response, as the "villain" was actually BrainwashedAndCrazy, and is [[GottaCatchThemAll one of the 108 Stars of Destiny]].
** In the other case, it's perfectly fine to take this option, as the character is legitimately a self-serving sleazeball who caused the death of the lead character's best friend out of nothing more than petty greed -- the conversation option for killing him actually ''reads'' "You're the one person I can't forgive."
** After Gremio, your protagonist's servant and protector, fools checkpoint guards into thinking that said protagonist is not the now-rebellious son of Teo [=McDohl=], but his own son, and begins to shout at him for never doing anything right, even now being mistaken for a criminal. He is then stopped by pleading guards from killing his 'son' right in front of them. After safe passage, Gremio apologizes to the protagonist for his improvised actings, to which you can actually respond to with ''"Unforgivable!"'' This can go on for a short while, and messing with him is all fun and laughs until it nearly results in him killing himself out of shame. Yikes.
* Subverted in ''VideoGame/DevilMayCry 4'', wherein Credo utters this to [[BigBad Sanctus]], who blatantly used Credo's sister as bait in his plans and thus the one thing that shook Credo's loyalty to the Order. The kicker? [[spoiler:He said it ''after'' Sanctus fatally wounded him, and got his ass further kicked for his trouble]].
* ''Franchise/FinalFantasy'':
** In the Japanese version of ''VideoGame/FinalFantasyVI'', after Cyan realizes that the Empire has poisoned Doma's water supply, he races around to find survivors, and when he races into his own room, he finds his wife and son dead. He screams at the Empire at the top of his lungs and [[RoaringRampageOfRevenge races off to kill as many Imperial soldiers as he can]], but not before muttering in shock.
-->'''Cyan:''' This is unpardonable...
*** Ruined by the otherwise okay Woolsey localization, which has Cyan yelling something like "THIS CAN'T BE HAPPENING! IMPOSSIBLE! IDIOTIC!"
*** Bonus points: The song played during the scene afterward, where Cyan is on his blind RoaringRampageOfRevenge? It's called [[https://www.youtube.com/watch?v=fhnkMgotQ6w The Unforgiven]].
** In ''VideoGame/FinalFantasyX2'', if you complete the BonusDungeon, the Den of Woe, your party encounters another imprint of the final boss, Shuyin. Paine explains that Shuyin's despair is what destroyed the Crimson Squad, that they went mad and all killed each other.
-->'''Shuyin''': (''regarding Nooj, Gippal and Baralai'') But these three lived. So... I decided to use them.
-->'''Paine''': You'll pay! ... ... (''after the battle'') No one uses my friends.
** Played straight several times in ''VideoGame/DissidiaFinalFantasy'', but [[LampshadeHanging lampshaded]] when the [[VideoGame/FinalFantasyI Warrior of Light]] confronts [[VideoGame/FinalFantasyVII Sephiroth]].
-->'''Sephiroth:''' Fighting me won't help you recover the [[MacGuffin Crystals]].\\
'''[=WoL=]:''' I suppose.\\
'''Sephiroth:''' Well then... Why come before me?\\
'''[=WoL=]:''' You hurt my ally.\\
'''Sephiroth:''' "I won't forgive you"... you might say?
** ''VideoGame/FinalFantasyTactics''. [[IdealHero Ramza]], a purer than pure hero who only draws his sword once during a cutscene, who tries to talk every enemy he meets out of fighting, who is as forgiving as [[MessianicArchetype JESUS]] finally finds three people in all of [[CrapsackWorld Ivalice]] even he will not forgive: [[spoiler:Algus Sadalfus, for shooting his adopted sister for no reason other than 'I'm a noble so I can do what I want'; Dycedarg Beoulve, his brother, for murdering their father, brother and trying to sacrifice their sister to an EldritchAbomination; and Folmarv Tengille, for resurrecting the aformentioned murdered brother as a self-aware zombie, and making him fight Ramza.]]
* Olaf of ''[[VideoGame/NintendoWars Advance Wars 2]]'' reacts this way upon seeing his [[DoomedHometown Hometown]] ravaged and toyed with by [[MadScientist Lash]].
* ''VideoGame/{{Shadowverse}}'': [[spoiler:When Eris summons multiple copies of the princess in the dream world in a [[EvilCannotComprehendGood futile effort to appease her]], Erika cuts them down like the fakes they are, but is still ''furious'' at Eris for forcing her to do so.]]
* UndyingLoyalty: To the princess.
* In one of ''VideoGame/SilentHill2'''s endings, [[spoiler:an illusion of Mary]] yells "Do you really think I could ever forgive you for what you did?" before [[OneWingedAngel transforming]] into the game's end boss.
* Shouted by Sion Barzahd before one of the final battles in ''VideoGame/TheBouncer''.
-->'''Sion:''' This is... This is unforgivable, Dauragon!
* When Teen Gohan transforms into Super Saiyan 2 form in ''VideoGame/DragonBallZBudokai 3,'' he screams "I won't forgive you!" If you don't know why, check ''Franchise/DragonBall'''s entry under the Anime section above.
* In ''VideoGame/CastlevaniaSymphonyOfTheNight'', Alucard confronts a succubus who has been imitating his dead mother just to mess with his head, and conveys his intentions [[TranquilFury rather stoically]] before an inevitable boss fight:
-->'''Alucard:''' Demon. Death is too good for you.
** He ''does'' say "Yurusan" in the Japanese, and is so VERY damn stone-cold about both that and the worse-than-death fate that his killing her in the dream-world will bring about (it's a death of the soul, so her spirit will never find rest and will wander lost for eternity). This followed by the only fade-to-black death in the game, and (in the original Japanese; the dub is uh...different) a very creepy cut-off scream from her.
*** And the sad thing is, you just ''know'' that he was a lot nicer than Dracula would have been if he found out about those shenanigans. 'Don't mention Lisa' is a good rule to follow.
* Ishida Mitsunari from ''VideoGame/SengokuBasara'', whose vocabulary seems to be largely limited to screaming either this or the [[SayMyName name of his rival Ieyasu]] at the top of his lungs. He even takes it one step further by refusing to forgive not only Ieyasu, but the ''whole world''. Even selecting him from the Character Select screen has him uttering "I will never forgive you".
* In the ''Franchise/AceAttorney'' series, there are two things Phoenix Wright considers completely "inexcusable", as he says in case 3-3: Poisoning, and betrayal. He has deeply personal and painful histories with both.
** Used for humor in the first case of ''VisualNovel/AceAttorneyInvestigations''. Someone was murdered in Edgeworth's office, and what about it gets him the angriest? His prized tea set is broken!
--->'''Edgeworth:''' ...Nnngh... That killer is going to pay! This tea set...!\\
'''Gumshoe:''' Yikes! You're really mad over this!\\
'''Edgeworth:''' This tea set is very dear to my heart and can only be bought in England. It cost more than your whole month's paycheck.\\
'''Gumshoe:''' W...Whaaaaaaaat!? Now I feel like the killer's wasted one of my monthly paychecks!
** The ProfessionalKiller, Shelly de Killer, places immense value on the trust between himself and his clients, so when Phoenix tells him that his client, [[spoiler: Matt Engarde,]] set up a hidden camera at the scene of De Killer's contract kill as blackmail in case things went south, he [[spoiler: immediately breaks his contract with Engarde, returns Maya to Phoenix, and swears that he will tirelessly hunt Engarde to the ends of the earth to exact his revenge. It [[BreakTheHaughty scares the everloving shit out of Engarde so hard]] that he ''begs'' to be sentenced guilty, on the off chance that might have an ounce more protection from de Killer if he's behind prison walls.]] The moral of the story: Don't piss off an assassin.
--->'''Edgeworth:''' You will finally receive the acquittal you wanted so badly. You should be happy. But before that, I would like to make one final statement. Some time in the near future, one very betrayed assassin may appear before you. Needless to say, that man is very good at what he does.
** Phoenix also views Franziska's suppressing a photograph during Maya's trial this way. It turns out there's more to this tactic than he thinks, but she is still trying to get Maya convicted by any means necessary.
--->'''Phoenix:''' (Unforgivable, Von Karma. Suppressing evidence like this... You're as bad as your father!)
* Surprisingly often used in ''VideoGame/FireEmblem''. For example, Renault versus Nergal in [=FE7=]: "[[spoiler:You villain... You cursed him! Your crime can never be forgiven! I will end you with my hands. In the name of my lost friend]]!" Or Jill versus Ashnard in ''[=FE9=]'': "[[spoiler:...Ashnard... Ashnard!! ASHNARD!! I...will never forgive you! NEVER!!!]]" Or Elincia versus Ashnard: "[[spoiler:Yet my purpose here is to defeat you. In the name of my father, my mother, my lord uncle, and the countless citizens of Crimea... You murdered them all! And I will never forgive you that!]]" Yep, FE loves this declaration.
** In the seventh game, [[ChildSoldier adorable assassin-in-training]] Nino is given the chance to confront [[spoiler:Sonia, the woman who murdered her parents and adopted her with the intention of raising her as a TykeBomb. This failed, so Sonia tries to have her killed. THAT fails, and Nino eventually joins the heroes. During their confrontation, Sonia gleefully admits to slaughtering Nino's parents. Nino doesn't take it well. "Aaahhh!!! You're no perfect being! You're a monster in human form! No mercy! No forgiveness!!!"]]
** Lyn in ''[[VideoGame/FireEmblemElibe FE7]]'' has two of these. The first is against [[EvilUncle her granduncle]], [[AristocratsAreEvil Lord Lundgren]], for trying to assasinate her, poisoning her grandfather (his own brother), and harming the people under his charge to whom he has a duty. The second is an actual utterance, when she, Eliwood and Hector discover [[spoiler:the murder of Leila, an Ostian spy and Matthew's lover]]:
--->'''Lyn:''' Unforgivable! This is... a foul deed. Beyond foul.
** In his own story path, Hector shares in the above (for Lyn's second This Is Unforgivable) by swearing a vendetta against the Black Fang until he finds the one responsible. He also echoes Lyn's "I have neither pity nor mercy for you" when he confronts [[BigBad Nergal]]. Notably, [[AllLovingHero Eliwood]] does ''[[SubvertedTrope not]]'' possess this quality despite Nergal killing his father.
* When X declares to Gate in ''VideoGame/MegaManX 6'', "Time to teach you a lesson, Gate! You used Zero's DNA to cause the Reploids pain. All for your own ego! I won't forgive you!"
** Also, for a villain example in said franchise:
--->'''X:''' So you're the Big Cheese?\\
'''Ride Boarski:''' Big Cheese?! Arggghhhhmm! How dare you call me that! I'm the Head Honcho, for crying out loud!\\
'''X:''' OK, whatever you say. I order you to disband this motorcycle gang!\\
'''Ride Boarski:''' Motorcycle gang?! Why you!! You've gone too far! I'll make you pay for this, with a duel!
** ''Maverick Hunter X'', the remake of the first game, features this from X towards Sigma before their final battle. "What you've done is unforgivable, Sigma!" At the time, Zero had just died [[note]](unlike the original, where his death happened two stages ago)[[/note]], and X is ''[[BewareTheNiceOnes furious]]'', and it's reflected in the dub delivery, which actually gives the line weight.
* In the ''VideoGame/{{Fallout 4}}'' DLC ''Nuka-World'', you can lead a gang of raiders and take over settlements for them. When you talk to Preston Garvey after taking over a settlement, though, he'll proclaim that any kind of friendship you two once had is gone.
-->'''Preston Garvey:''' You've crossed the line, General! There are some things I can't forgive!
* ''{{VideoGame/Rosenkreuzstilette}}'':
** After laying her undead grandfather Raimund Seyfarth back to rest in her alternate mode, Grolla, both infuriated and deeply hurt, declares this trope in vowing to punish Graf Michael Sepperin for disrupting his peaceful slumber.
--->'''Grolla:''' Michael Zeppelin... your reasons mean nothing to me. There will be no mercy. You shall pay for this with your life.
** In the main game, Spiritia and Lilli say two variations of this trope to [[spoiler:Iris in Iris Stage 3. First, Lilli shouts out "You're gonna pay!" to her, and Tia follows with the common variation of "Iris, I'll never forgive you!"]]
** Zorne is quite fond of using this trope, especially as one of her pre-battle quotes or when Grolla confronts her after having defeated her friend Trauare, which is one of quite a few things that can press Zorne's BerserkButton.
--->'''Zorne:''' About time you showed up, Grolla! If it weren't for you, Trau would still be a part of RKS! You're gonna pay for that!
* VideoGame/GuiltyGear uses some "This Is Unforgivable" moments as well. For example, May says this to I-No when she catches her tormenting and hurting her friend Dizzy.
* ''VideoGame/BlazBlue'' is another game that also likes this trope. For example, Ragna the Bloodedge, the main protagonist, says this when he uses Hell's Fang on his hated rival Jin Kisaragi. The same thing is also done in his winquote against him.
-->'''Ragna:''' I'll never forgive you, you son of a bitch. I was gonna tell you to die a slow, painful death, but I don't got the patience to wait around, so you're dying now.
** Also, in ''[[VideoGame/BlazBlueContinuumShift Continuum Shift]]'', Kokonoe declares this to Hazama when he fights Lambda-11 in his arcade mode run.
-->'''Kokonoe:''' I've just got one question to ask you. Why did you betray my mother?\\
'''Hazama:''' "Betray?" Come on, don't give me that. It's not like the Six Heroes were buddies... then the other day, I told the old man, "We're buddies, right?!" Hahahaha!\\
'''Kokonoe:''' You... you bastard! I'll never forgive you! Lambda! Kick the shit out of him!
** And for the encore there's this exchange between Ragna and Hazama/Yuuki Terumi in ''Continuum Shift'''s True Ending:
--->'''Ragna:''' Terumi... ''Terumi''... I will ''never forgive you''!\\
'''Hazama:''' You won't forgive me? Like I give a damn! Just shut up and die already!
** Since Hazama/Yuuki Terumi is [[spoiler:sustained by hatred, never forgiving him is playing him straight into his hands... Which ''really'' is a bloody shame, because he is good at crossing the MoralEventHorizon and then pushing waaay past it, to infinity and beyond. ForTheEvulz]].
* Reimu Hakurei of ''Franchise/TouhouProject'' uses these words when Sanae Kochiya fights her in her story run in ''Touhou Hisoutensoku'' because she accuses her of making a huge pitfall trap for her to fall into:
-->'''Reimu:''' Talk is cheap! Making such a huge pitfall trap is unforgivable!
** As does NinjaMaid Sakuya Izayoi in ''VideoGame/KoumajouDensetsu II'' during the final battles upon learning that Yukari was behind everything that happened with her mistress:
--->'''Yukari:''' Ah, I wonder if the air was too heavy for a vampire.\\
'''Sakuya:''' Yakumo Yukari... [[YouExclamation you!]][[labelnote:*]]Just in case we're not fully aware of how pissed Sakuya is, the particular form of "you" she uses here is ''kisama''.[[/labelnote]]\\
'''Yukari:''' Hahaha...don't let yourself boil over yet. There's more to come.\\
'''Sakuya:''' I can't...I'll never forgive you for this![[labelnote:*]]The Japanese Sakuya uses here is "''Omae wa zettai ni yurusanai!''" which translates to "I will absolutely not forgive you!" In other words, Yukari is in for one hell of an asskicking.[[/labelnote]]
* In ''VideoGame/AdventureQuestWorlds'', the hero helps the Great Godfather of Soul send a Royal Jar of Honey to Lord Ovthedance as a peace-offering in order to help him get the magical shoes the Horc used to cheat him out of victory in dance contests. What the hero doesn't know is that the Godfather was setting up Lord Ovthedance by claiming he cheats in dance contests. After beating him and realizing that his shoes aren't enchanted (the Lord didn't need enchanted shoes to win anyway), the hero realizes that the Godfather lied and used him/her, [[ApologeticAttacker apologizes to the Lord for seeing to it that he's in no shape to dance at that point]], and decides to show the Godfather who's boss. After receiving dancing lessons from Lord Ovthedance, he/she challenges the Godfather to a /Dance-Off competition, and wins the /Dance /Dance Minigame, taking the title of Dancing Champion. The Godfather isn't too happy about that, and that's when, while he declares this trope to the hero, Chaos Lord Discordia is mentioned for the first time ever by him.
-->'''Great Godfather of Soul:''' Have you come back to rub your victory in my face, hero? Someday, with Chaos Lord Discordia's help, I'll make you pay for taking my title from me! You can count on that!
** In the Golden Ruins area of the Frostval events, the hero and Blizzy confront Maximilian Lionfang, who has kidnapped the Spirit of Frostval and stolen the presents from the town of Frostvale. Believing that the world must suffer for bending its will to evil and that there can be no peace until all evil is completely and permanently vanquished, Lionfang [[KickTheDog burns the presents with his whip]] as a demonstration of one of the "prices that Lore must pay for the pathetic truce between Good and Evil." A horrified Blizzy lets out a BigNo, Lionfang gives off an EvilLaugh, and the hero doesn't take that too well. He/she shouts to him, "You'll pay for that!" before proceeding to hand his butt to him on a plate for the second time and afterwards tell him, "[[MemeticMutation Keep the change, you filthy animal,]]" which is also a memorable line from ''Film/HomeAlone''.
** In the 2011 Friday the 13th event:
--->'''One-Armed Bandit:''' My gang is all over this area. You'll never make it to that ship! ''[to Voltaire]'' You with the guitar... This is all YOUR fault. I'll get you for this!
*** He said that to Voltaire because he blamed him for his involvement in the hero defeating him, and wanted revenge on him for it. He would later keep true to his desire for revenge against him by ambushing him during their confrontation with Lord Krom Wrath, and dragged him somewhere where they could settle their score while Deady in his OneWingedAngel form of Urkor Malravenus fought Krom Wrath and the hero used the Vorutanian Key Blade to beat Yahorneth, save the world from being taken over by the Necrus and Krom Wrath, and force the Necrus to retreat back to Necronus. It later turned out that Voltaire survived his fight with the One-Armed Bandit and in the process of doing so got his mechanical claw in place of one of his hands.
** In Doomwood Part 2, Gravelyn calls out Noxus [[spoiler:for betraying her and having Chaos Vordred take her hostage]].
** In the Bloodtusk saga, after sending the Horcs and Trolls back home to rest up from all the fighting they did after defeating the alliance soldiers led by Cynari and Tibias, the hero makes a declaration that, when he/she finds the Chaos Lord running the madness taking place in Bloodtusk Ravine, he/she will make them pay, especially for murdering Antiphuus. He/she also gets an idea on where to start looking for information on the Chaos Lord. [[spoiler:The Chaos Lord later indeed turns out to be Krellenos.]]
--->'''Hero:''' '''DRAKATH!''' I know you have a hand in this. When I find your new minion, I will make them PAY! And I need to know who! ...I'm not sure where to start, but I think I have an idea.
*** Later, in the same saga, [[spoiler:Khasaanda has become enraged at Krellenos for abandoning her, ruining everything about the ravine and having chaorrupted and caused the death of their own brother. So what does she do? She usurps his Chaos powers and then kills him using a telekinetically-driven weapon from a chaorrupted Alliance soldier. After that, she plans to use her new Chaos powers to exact revenge on Drakath for the chaorruption and deaths of her brothers]].
** The finale of the Swordhaven saga has the Hero declaring his/her intent to make Drakath himself pay for [[spoiler:driving King Alteon to madness through his chaorruption, causing the death of Princess Brittany at the hand of her own father, and the horrible devastation wrought upon Swordhaven by the Chaos Dragon]].
* Shouted by the protagonist of ''VisualNovel/TokimekiMemorial 2'', when [[VictoriousChildhoodFriend his childhood friend Hikari]] is his battle partner and has activated her TakingTheBullet LimitBreak to save him from the enemy's LimitBreak. He then enters in an UnstoppableRage that dramatically ups his Attack Power.
* In the seventh dungeon of ''VideoGame/PaperMario64'', the Crystal Palace, one of the puzzles to solve involves Bombette and five Duplighosts disguised as her. This puzzle is quite simple to solve, really - all Mario has to do is hammer all five of the Duplighosts disguised as her. As a matter of fact, Mario can tell who the real Bombette is because she's the one who says that she will never forgive him if he messes up.
* In ''Franchise/OnePiece: Unlimited Adventure'', when Robin says before the fight with Eneru that she'd rather not see him again (in canon, he nearly killed her and almost destroyed Sky Island), an audio clip of her saying "Unforgivable!" is heard. When Shanks uses his ultimate attack, he yells "I won't forgive those who hurt their friends!" (a mistake in pronouns, as it's a reference to his being willing to tolerate insults, but not those who threaten ''his'' friends)
* ''VideoGame/{{Pokemon}}'':
** In the ending of ''VideoGame/PokemonXDGaleOfDarkness'', Ardos tells Michael he can't be forgiven for foiling Cipher's plans so utterly.
** Cheren drops an "I'll never forgive them for this!" regarding Team Plasma in ''VideoGame/PokemonBlackAndWhite''.
** In ''VideoGame/PokemonXAndY'', this is what Emma tells the Kanto woman (who had just insulted Looker) when she reveals that she [[BilingualBackfire can speak Kantonian]].
*** Also, earlier in the game, the Poké Ball Factory's president shouts at Team Flare, who had just invaded it, that he will never forgive anyone who tries to steal all of the Poké Balls for themselves.
** In ''[[VideoGame/PokemonRubyAndSapphire Pokémon Omega Ruby and Alpha Sapphire]]'', the respective villainous team leader receives this [[spoiler:from himself after they realize all the destruction their ambitions would have cause had the player not been there to stop the legendary Pokemon.]]
** In ''VideoGame/PokemonSunAndMoon'', [[spoiler:Lusamine says to Lillie that she will never forgive her for keeping Cosmog away from her for so long. Sadly for her, with MoralMyopia in play, it doesn't justify the fact that she tortured Cosmog into opening up multiple Ultra Wormholes all over Alola against its own will earlier]].
* In ''VideoGame/DeusEx'', after you [[spoiler:escape from UNATCO, Gunther]] says in a voice full of hate "No, I cannot forgive. No... not the killing of [[spoiler:Agent Navarre.]] I will follow you. Denton; I will get you!
* In ''VideoGame/MassEffect2'', Paragon Shepard can state this during a conversation with Mordin, where he reveals that he redistributed a modified form of the genophage to the Krogan, since they were adapting to the previous strain of the Virus. While Mordin rationalises it that it was simply to keep the Krogan numbers in check so they could not threaten the Galaxy again, Shepard gets ''pissed'', calling it practically a War Crime that the Salarians don't have the courage to admit responsibility for.
** Paragon Shepard also has this attitude when discovering the true purpose of Project Overlord, where the Paragon Interrupt is pistol-whipping Dr. Gavin Archer for [[spoiler:experimenting on his brother and hooking his mind into a machine]]. When Shepard re-encounters him in ''3'', it's clear they ''still'' have nothing but utter contempt for him, even if they are currently saving his life again.
** Paragon Shepard can invoke this in ''3'' to try to end the Geth and Quarian [[RobotWar conflict]], stating that the Geth ''don't'' want to fight the Quarians and that throughout their history, all they've done is act in self-defence due to the ''Quarians'' being the aggressors in the conflict. With a high enough Paragon rating, Shepard can even end the entire war by brow-beating the Quarians into a cease-fire.
* ''VideoGame/{{Persona 4}}'''s Yosuke Hanamura yells this at [[spoiler:Adachi Tohru]], who has just taunted him and the rest of the Investigation Team with [[spoiler:the fact that he was the one responsible for the murder of both Mayumi Yamano and Yosuke's beloved senpai Saki Konishi, as well as manipulating Namatame into carrying out his evil work, all for his own twisted amusement]].
-->'''[[spoiler:Adachi]]:''' [[ShutUpKirk You can keep your forgiveness.]]
* ''Franchise/TheElderScrolls''
** In the series' backstory, Zurin Arctus, [[GodEmperor Tiber Septim]]'s [[CourtMage Imperial Battlemage]], was tasked by Septim with figuring out a way to power and control the Numidium, a HumongousMecha of [[OurDwarvesAreDifferent Dwemer]] construction which Septim acquired as part of the Armistice with the [[PhysicalGod god-kings]] of Morrowind. [[MultipleChoicePast While there are several versions of the events that followed]], Arctus would become (or [[MergerOfSouls become part of]]) the undying being known as the Underking, whose soul was placed in the [[SoulJar Mantella]] to power the Numidium. Septim would use it to complete his conquest of Tamriel, but would then start using it backhanded ways Arctus/the Underking did not intend (such as destroying the neutral royal families of Tamriel so that he could enthrone persons he knew to be loyal). The Underking considered this unforgivable, confronted Septim about this misuse, and then flew into a rage, in which he destroyed the Numidium and blasted the Mantella into [[SpiritWorld Aetherius]]. One of the [[MultipleEndings possible endings]] of ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'' is to return the Mantella to the Underking, [[ICannotSelfTerminate finally allowing]] [[WhoWantsToLiveForever him to die]].
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', in one of the late Thieves' Guild quests, you enter a dungeon to find an entire group of bandits slaughtered. When you meet up with your friends, they explain that it was the work of the traitor you're hunting down. Brynjolf says this:
--->'''Brynjolf:''' Crime is one thing. ''Murder'' is another. [[spoiler:Mercer]] will pay for this.
* In ''VideoGame/InjusticeGodsAmongUs'', at the beginning of the fight between {{Franchise/Batman}} and Regime Nightwing [[spoiler:who is actually Damien Wayne]], Batman tells him
-->'''Batman:''' [[spoiler:You stopped being my son when you killed Dick Grayson. He was my son.]]
** After the fight his victory line is:
--->'''Batman:''' You're dead to me.
* ''VideoGame/StarWarsTheOldRepublic'': The Consular's eventual Padawan, Nadia Grell, is a sweet daughter of a senator, and one of the nicest people you will ever encounter in the game. Daddy Grell turns out to be a fine statesman and stalwart ally of the Consular until the Sith kidnap him. When Consular and Nadia charge in as BigDamnHeroes to save Daddy Grell, it's too late - the Sith tortured him to death. Sweet little Padawan Nadia ''[[BewareTheNiceOnes loses it,]]'' and if the Consular isn't convincing enough in the subsequent conversation, that Sith is ''dead'' by her hands.
* ''VideoGame/{{Stellaris}}'': Holy Guardians may have a number of planets designated as [[HolyGround Holy Worlds]]. Colonizing them will make them angry enough, but using a [[EarthShatteringKaboom Planet Cracker]] will get this response:
---> (Planet name) was a holy world.
---> [[PreAssKickingOneLiner You do not know the true extent of your sin.]]
---> [[ThisMeansWar Not yet.]]
* In ''VideoGame/SlyCooperThievesInTime'', [[spoiler:Penelope committing a FaceHeelTurn and betraying Bentley's heart]] has caused Sly to declare war on [[spoiler:her]], not long before [[spoiler:she [[MoralEventHorizon steals Sir Galleth's cane]].]] It looks like [[VideoGame/Sly3HonorAmongThieves Dr. M]] did managed to get through to one member of the Cooper Gang, after all, though not Bentley.
* In ''VideoGame/LufiaCurseOfTheSinistrals'', Selan declares this ad verbatim when the Sinistral Gades brings a meteor storm down on Parcelyte.
* [[HookerWithAHeartOfGold Lauren Winter]] from ''VideoGame/HeavyRain'' swore on [[MamaBear her son's grave]] that, no matter who his killer was, she would kill him, but she is particularly angry when she realizes that it's [[spoiler:Scott Shelby, the man helping her track down the killer. If she's alive, she curses him on his grave or, if he kills everyone else, guns him down in the street.]]
* In ''VideoGame/FreedomPlanet'', Lilac and Carol shout this at Brevon in anger beyond words [[spoiler:after he has turned Milla into a monster and forced them to fight her to the possible death. After smashing up on his mech armor, Lilac keeps on the offensive with this trope, stating that she will use the wrath of her dragon might to make him pay for it]].
* In ''VideoGame/FTLFasterThanLight'', enemy ships that you are close to destroying will sometimes plead surrender, offering you rewards for sparing their lives, with the option to reject that and finish off the target instead. If the enemy ship is a pirate ship, the "don't accept surrender" option is labeled as "Piracy cannot be forgiven. Attack!"
* In ''VideoGame/ShinMegamiTenseiIVApocalypse'', the FinalBoss [[spoiler:YHVH, i.e. ''God'',]] offers you several chances to cease your offensive against them, turn back, and receive their forgiveness ([[spoiler:the last of which is actually a trap that will result in an immediate GameOver]]), but once you [[spoiler:ReasonYouSuckSpeech the divinity out of him and reduce him to a hideous monstrosity]], they declare that you are beyond forgiveness:
-->"Impudent humans, '''I cannot forgive you!''' I asked only that you take the life I gave you and obediently follow my word. The weight of your blasphemy is too great for death. '''[[FateWorseThanDeath Eternal suffering]] is the only suitable punishment!'''"
* When you first meet Kormac the Templar in ''VideoGame/DiabloIII'', one of your first objectives is to assist him in killing his former comrade Jondar, who had [[FaceHeelTurn defected]] to the [[{{Cult}} Dark Coven]]. Jondar's final words upon his defeat are to beg for forgiveness, stating that [[BrainwashedAndCrazy his mind had been clouded by "the Coven's evil magic"]]. Kormac refuses to take it, declaring, "Betrayal can never be forgiven," and delivers a CoupDeGrace.
* In ''[[Manga/KishinDoujiZenki Kishin Douji Zenki FX: Vajura Fight]]'', Chiaki shouts "Yurusenai!" towards a Hyouijuu named Fushushoku once she discovers that he put Nozomi, the girl that she and Zenki have been saving multiple times over the course of the game, through DemonicPossession before blasting at him with one of her shots. The two get a chance to get revenge on him during the penultimate boss fight against another Hyouijuu named Razurou (who also gets possessed by Fushushoku as well), and after they beat down the possessed Razurou and reduce him to a mere skeleton, Fushushoku is later killed immediately afterwards by the game's BigBad and final boss, Marubasu, whom Chiaki ultimately decides was responsible for Nozomi's brainwashing and death.
* When Franchise/{{Kirby}} first meet Flamberge in ''VideoGame/KirbyStarAllies'', she is seething with rage at him and calls him out for what he did to her sweet beloved sister Francisca, and vows to "scorch him to such a degree that she believes that even roasted marshmallows will seem like ice cubes compared to him." Judging by the pause-screen description of her first boss fight, you pretty much know what she means.
-->'''Flamberge''': HEY, YOU! Stubby little... pink thing! Yes, YOU! I have a buuuurning question for you! You're the one who was so rude to sweet Francisca, aren't you?! Don't you dare try to deny it! Fiend! Coward! I swear, if you've harmed a single blue hair on her perfect head... you'll BURN for it!!! Jamblasted!! I will never EVER forgive you! Now you must face Flamberge! That's ME! For what you've done, I'll scorch you to such a degree that... that... even tasty, toasty marshmallows will seem like ice cubes compared to you!
** [[spoiler:Later, when you get to Hyness and he delivers his crazed and incredibly long MotiveRant complete with UnreadablyFastText, part of his rant says that he refuses to forgive the ancients for leaving him and his followers banished to the edge of the universe to be forgotten.]]
* In ''VideoGame/DragonAgeOrigins'', as you journey through the Deep Roads you slowly learn what Branka did/allowed to happen in the name of her quest. Her lover Hespith asks you to forgive Branka, but then decides no, she cannot be forgiven.
* Discussed in ''VideoGame/BatmanArkhamKnight''. The Arkham Knight's militia seems to be made of disgruntled/disgraced former soldiers. At one point, one of them will [[EnemyChatter talk about]] about how what there will be not turning back or forgiveness for what they're about to do (committing an act of domestic terrorism by detonating a chemical weapon). No on else cares.
* Sakura Ogami from ''VisualNovel/DanganronpaTriggerHappyHavoc'' shouts this when she learns someone has harmed Aoi. She even has two relevant [[VoiceGrunting stock voice clips]]: "I can't forgive this!" and "No forgiveness!"
* Bayek of ''VideoGame/AssassinsCreedOrigins'' shouts this to [[ArchEnemy Flavius the Lion]], due to him forcing Bayek to stab his son in the heart by accident. Gains even more weight when you remember Egyptian mythology states that if the heart is damaged, the deceased is barred from the afterlife.
* In ''VideoGame/GodOfWarPS4'', [[spoiler: the Aesir god Baldur was magically given immortality by his mother Freya ''against his will'', because she was terrified of him dying a pointless death that would [[TheEndOfTheWorldAsWeKnowIt kick-start Ragnarok]]. Her spell made Baldur immortal...but also left him completely unable to feel ''anything'', [[SenseLossSadness driving him insane]]. When Freya refused to undo the curse, despite her son's [[AintTooProudToBeg pleading for her to do so]], Baldur snapped; though he couldn't bring himself to kill her, he made sure Freya knew he never wanted to see her again. When they finally meet again a century later, a hundred years of complete sensory deprivation has destroyed any lingering affection Baldur had for Freya, leaving him a wrathful berserker consumed by his hatred for his mother and driven only by his need to kill her. Even when, thanks to Kratos and Atreus, the curse is broken, Baldur spurns his mother's desperate pleading for forgiveness, snarling that there is nothing she can do that would even remotely begin to atone for what he's suffered thanks to her meddling]].
* Meta example in online gaming. Hacking ranks among the top, unforgivable gaming sin, that permaban for first offense is almost always standard issue. To put in perspective, ''VideoGame/EVEOnline'' devs won't lift a finger on you being a troll, scamming people, or just being a jerk to anyone you meet, but even they would not tolerate hacking. Some devs take this further with lifetime permaban, meaning not only your account is banned, but you as a person would forever be excluded from the game and related events, even if you make new accounts on completely new machines (assuming they find out).
* ''VideoGame/TrialsOfMana'':
** Never had Duran felt so humiliated until the very night where a powerful mage named the Crimson Wizard injured his fellow soldiers, defeated him in battle, and insulted his beloved King Richard in front of him. When he meets the king before setting off on his adventure, he discusses with him that he can't forgive the wizard for what he did and that he has no plans to return home until that wizard has answered for his crimes against Valsena.
** Kevin became angry at his dad after overhearing him converse with Goremand about their act of turning the cute wolf puppy Karl into a monster and forcing him to knock him down and making him think he killed him. He became so angry that he ran after his father and not only disowned him but also attempted to attack him only to get knocked out of the castle. When he returns to Ferolia, and challenges his dad after having been forced to give the Mana Sword to the Masked Mage's faction, he has this to say to him (and that's just right before learning the truth about him and what really happened to Karl):
--->'''Kevin''': Never forgive you! You hurt Karl!
** Riesz was also rubbed the wrong way upon learning that Belladonna arranged for her brother Elliot's kidnapping as well as her father Joster's assassination and the ruin that was brought to her home in Laurent, and she understandably swears to make her pay. When she confronts her at Dark Castle in her own story, she states to her that she does not intend to let her get away with every horrible thing she and the rest of the Dark Majesty's resurrection faction have done up to that point.
--->'''Riesz''': I won't let you get away, Belladonna! {{You killed my father}}!
* In ''VideoGame/{{Undertale}}'', there is this PreAsskickingOneliner by [[spoiler: [[ThePrankster Sans]] if you are in the Genocide Route.]]
-->[[spoiler: '''Sans''':]] "it's a beautiful day outside. birds are singing, flowers are blooming... on days like these, kids [[KidsAreCruel like you]]... [[spoiler: '''[[LetsGetDangerous Should be burning in hell.]]''']]"
* ''VideoGame/OctopathTraveler'': During her confrontation with the Ghisarma, H'aanit states the killing other animals and people for no reason other than taking out its anger is this trope. H'aanit follows it up with declaring the Ghisarma must be killed.
[[/folder]]

** The Joestars are well known for not just their determination and ability to withstand pain, but also their compassion and unwillingness to forgive evil. Giorno Giovanna, [[spoiler:the son of DIO conceived through Jonathan Joestar's body]], exemplifies this in his own way. His goal is to take control of the Italian mafia gang, Passione, and reform it to be a force for good, to protect innocent people, and he won't spare anyone who harms the innocent. One example of this is when he kills Polpo by making him unwittingly eat his own gun, using Gold Experience to turn it into a banana, which ended with Polpo involuntarily shutting himself in the mouth. Prior to this, Polpo's Stand, Black Sabbath killed an old janitor, and Polpo showed no remorse or care for anyone who got killed because of his Stand's action, due to his belief that God is willing to forgive murder when someone insults you. Giorno takes this to heart when he commits the murder of Polpo.

* This was practically the CatchPhrase of Cure White from ''Anime/FutariWaPrettyCure''. Cue asskicking of the MonsterOfTheWeek. Sometimes Cure Black said it at the same time, which is the leading cause of death among ''Franchise/PrettyCure'' villains.

* Subverted in ''Series/{{Arrow}}''. In the Season 3 Premier, Malcolm Merlyn brainwashes Thea into (his own daughter) murderering Sara, in order to instigate conflict between Oliver and Ra's al Ghul. In the finale, Oliver tells him "I will never forgive you for what you did to Sara"...and then makes him the new Ra's al Ghul, effectively '''rewarding''' him for the deed. From that point onward, he never has any objection to [[EnemyMine working with]] Malcolm, thanks him for his cooperation if they ''do'' work together, comes up with excuses to not remove him as Ra's (though he eventually does), and repeatedly refuses to kill him. Apparently, he forgave him for everything.
** Played straight with Laurel, Sara's sister, who repeatedly argues for killing Malcolm. Even after Malcolm helps resurrect Sara, Laurel still hates him and wants him dead for killing her in the first place.

* ''Anime/KazemakaseTsukikageRan'': A CatchPhrase of the honor-loving titular character is "Utterly Inexcusable!" which she tends to see a lot in the acts committed by others which prompt her to take action against them.

** [[NotSoDifferent Laharl says the same thing]] later on when someone messes up his hair. [[spoiler:This is a clue that Mid-Boss is actually his father in disguise.]]

* {{Subverted}} in ''Fanfic/TheUnfantasticAdventuresOfBizarroNo1''. SelfDemonstrating/{{Bizarro}} and his race might forgive the [[ManOfKryptonite Blue-Kryptonite Men]] for attempting to wipe them out. The Blue-K Men's attempt to sculpt their cubic-shaped Bizarro World into a round planet is an unforgivable insult, though.

* Mimi of ''Anime/DigimonAdventure2020'' declared that she would never forgive Andromon for [[spoiler:killing the Guardromon who had been helping the Chosen Children.]] Naturally, this resulted in [[spoiler:Togemon evolving into Lilimon and completely defeating Andromon.]]

-->'''Tao Len:''' ...You took my friend away and YOU'RE GOING TO PAY!!

** A villainous example that is played for laughs with Boris, one of Hao's followers. The minute Horohoro points out that his teammate, Kouji Yamada (or Damayaji however you want to refer to him), looks more like a vampire than him, Boris immediately and flips out, breaks down crying and screams "Unforgivable!" at the thought of being "compared to a miserable creature" in a humiliating way, [[DisproportionateRetribution and proceeds to kill his own teammate to destroy any confusion]], afterwards blaming Team Yoh for the humiliation. He later screams this again when Ryu manages to punch him in the face.

** In the anime, after Hao eats his brother Yoh's spirit (after which he attempts to digest it and therefore cause him to become one with him), Yoh's friends fly into a rage and make several futile attempts to attack him out of unforgiveness towards him. Even his fiance Anna says that she will never forgive him. Things settle down a lot when Manta helps them defeat his Shikigamis, though, and more so when Yoh regains his spirit to the relief of all of his friends, and Anna welcomes him back.
