* Oh, how shall we count the ways in which ''Manga/PandoraHearts'' does this to us? First, Oz thinks he stabbed Gil early in the series and freaks out [[spoiler:He lived.]] Then Oz undergoes one around [[spoiler:the time he discovered [[TomatoInTheMirror he was actually B-rabbit]] and thus responsible for Alice killing herself to save him and also when he makes her disappear.]]]] [[TearJerker The chapter title for 75 is called "Alone" for a reason.]]
** Alice herself in Retrace 76 where she [[spoiler:screams a big no upon seeing her sister die and say it's all her fault that everything happened. Then it turns into a CrowningMomentOfAwesome when she decides to undo everything and wipe her memories.]]
** [[spoiler:Jack himself sobs while holding Glen's head, saying Glen was the only friend he'd ever had....[[TearJerker and he's just killed him.]] ]]
** [[spoiler:Elliot and Break both get this. Elliot when he learns he murdered his brothers unintentionally by way of possession.]] In short, Pandora Hearts is FULL of this. Especially the recent chapters.
* Sayaka from ''Anime/PuellaMagiMadokaMagica'' has this reaction when she makes Madoka cry after she yells at her for not using her latent power to fight witches. Unfortunately, this realization helps push her towards the [[spoiler: DespairEventHorizon and she becomes a witch.]]
** Not to mention Madoka herself had this reaction two episodes prior, after throwing Sayaka's Soul Gem off a bridge and onto a moving truck to keep her out of a fight [[spoiler:only to find out that said Soul Gem [[SoulJar literally contains Sayaka's soul]], and by throwing it away she almost killed Sayaka.]]
* Robin Mask suffers from this when he thinks he's killed {{Kinnikuman}} during their fight in the 20th Choujin Olympics. Especially noteworthy in that Robin was previously in an UnstoppableRage- once it wears off, he realizes that he was taking the fight to seriously. While he's lamenting, Kinnikuman puts him in a finishing hold, winning the match.
* ''Anime/DragonBallZ'': Vegeta had this twice, once when he allowed Perfect Cell to reach his perfect form and again when he allowed Majin Buu to resurrect.
** Gohan had this too, thanks to his cockiness.
** Vegeta after [[spoiler:Future Trunks gets murdered by Cell. He realizes he's neglected his own son and goes on a RoaringRampageofRevenge.]]
** A short while before the above example, Goku had one of these moments on his own when Piccolo [[WhatTheHellHero reminded him]] that Gohan was [[HalfHumanHybrids partially human]], didn't share [[ProudWarriorRaceGuy Goku's]] lust for battle, and thus didn't find any pleasure at all in getting [[CurbstompBattle curbstomped]] by Cell while his father simply looked on from a distance.
** In the Buu saga, Piccolo tells Super Buu to kill the people of Earth, hoping that it will stall him and intending to wish back everyone with the Dragon Balls later. However, Buu then fires the [[KillAllHumans Human Extinction Attack]] and kills everyone in the world in less than three minutes, leading Piccolo to have this moment.
* In the OVA of ''AngelSanctuary'', Katan says this while looking down at his hands in horror after [[spoiler:accidentally killing Sara, when he was actually aiming for Setsuna]].
* ''MagicalProjectS'' Misao Amano (as her [[SuperpoweredEvilSide evil]] MagicalGirl alter ego Pixy Misa) was destroying the city and almost killed [[FriendlessBackground her only friend]] Sammy and her parents, to the point where she [[spoiler:ran away due to guilt]], this was justified although it was her other personality did this and was unaware of what she did. The twist here was that [[spoiler: what she did was realy her (her repressed aspects,) and [[NotBrainwashed not brainwashing]]]].
* Guld Bowman In ''MacrossPlus'' gets a simultaneous double helping of this, when he finally overcomes his TraumaInducedAmnesia in the middle of a MacrossMissileMassacre which he believes has killed Isamu Dyson, the person who he had blamed for the trauma. [[spoiler:Actually caused by his own attempted rape of Myung, a memory he had suppressed until that moment]].
* For a villainous example, in the 3rd ''Manga/{{Naruto}}'' film (''Guardians of the Crescent Moon Kingdom'') the [[TheDragon baddy]] Ishidate accidentally turns his employer--and more importantly, paymaster--to stone. OhCrap.
** Sakura has this reaction when she realizes what the promise she got out of Naruto did to him.
* ''Anime/DigimonAdventure02'': It's discovered that BigBad Ken Ichijouji, definitely an EvilOverlord with a ZeroPercentApprovalRating, never knew Digimon were sentient, thinking the Digital World to be a very, ''very'' realistic [[VideoGameCrueltyPotential video game]]. He gives this line once he finds out he's done real harm, and makes a HeelFaceTurn.
* Yamaki of ''Anime/DigimonTamers'' actually yells this under the dramatic and appropriately messed-up sky created by his program Juggernaut, an attempt to purge digital life from reality that instead results in a massive and highly dangerous breach between the worlds. Of course, this a fellow about whom the line, "Looks like your pal Yamaki ripped open the sky again," has been uttered. This of course leads to him being fired, and after a good sulk, he begins his HeelFaceTurn.
** [[BloodKnight Beelzemon]] spends a good deal of time wandering the Digital World listlessly, thinking back over his actions after [[spoiler: he kills Leomon and is later saved by Leomon's Tamer, Jeri]]. He's so disgusted by himself that he completely loses the will to fight and even to live, not even ''trying'' to fight back while a group of Chrysalismon beat him halfway to death. He (somewhat) snaps out of [[VillainousBSOD it]] when he finds out that Renamon and Rika risked their lives to find him, and, well...[[HeelFaceTurn I think you know]] [[TheAtoner where this is going]].
* Shinji Ikari in ''Anime/NeonGenesisEvangelion'' has a HeroicBSOD after he is forced to kill [[spoiler:the angel Kaworu]].
** And another one after his EVA nearly kills Toji Suzuhara due to his inability to fight. [[spoiler:This haunts him to a greater degree in the manga since he ''actually'' kills Toji, and Kaji tells him to take accountability because he didn't try harder to save him, just standing by until his father activated the Dummy Plug]]
** In the third RebuildOfEvangelion movie, Shinji has not one, but three such moments - [[spoiler: First, when Kaworu shows him the devastation caused when he [[NiceJobBreakingItHero inadvertedly set off the apocalypse]] in a desperate attempt to save his de-facto girlfriend during the climax of the previous movie. Next, word-for-word, when he realizes that, on top of that, it was completely for naught since the girl in question is still dead and what he thought was her is just a clone of hers, which tears away the only coping mechanism he had. The third time occurs when he sets out to [[TheAtoner atone]] for this and sets out to SetRightWhatOnceWentWrong. Except, the ResetButton [[TheCakeIsALie is a lie,]] and all the supposed [[UnholyHolySword "Spears of Hope"]] will do is to blow the pathetic remainder of humanity to hell. As he sees the destruction begin around him, he reacts with utter mortification. Needless to say, by the time that movie is over, he's reduced to a near-catatonic shell, mad with grief and guilt.]] And the poor thing is only ''fourteen''.
* Renton from ''Anime/EurekaSeven'' does this after he goes berserk and tears an army of enemy LFO's to shreds. He doesn't really have enough time to ask of God what he has done. He, instead, loses his lunch over the debacle.
** The impact of this cannot be fully felt if you don't realize that up until this moment Renton (and many members of the audience) didn't realize that the entire time he's been fighting enemy LFO's, he's been killing people. He simply thought that enemy LFO's were robots.
* Lelouch from ''Anime/CodeGeass'' has a DelayedReaction version of this when the memory of his murder of [[spoiler:his half-brother Clovis]] from the previous episode causes him to vomit (you see the bathroom sink water running indicating he did get sick).
** Suzaku also has one of these [[spoiler: when he realizes he's JumpingOffTheSlipperySlope by trying to drug Kallen to get information out of her]]. Followed by [[spoiler: Nina Einstein, once she witnesses the horrendous results of her FLEJIYA nuke.]]
** Lelouch actually has another one of these, when he [[spoiler:loses control of Geass and Euphemia gets hit with his off the cuff command to KILL ALL JAPANESE PEOPLE!]] The look of utter shock on his face spoke volumes.
*** Earlier in the series, he gets a similar expression upon being informed that [[spoiler:his love interest's father was among the casualties of his latest battle.]] Although this isn't as objectively big as the aforementioned incident, it shook Lelouch rather badly and forced him to personally face the consequences of his actions and orders.
** Darlton gets one of these [[spoiler: after his hypnosis wears off and he realizes he just saved Zero by shooting Cornelia in the back.]]
* Mikoto from ''Anime/{{Mai-HiME}}'' breaks down when she realizes [[spoiler:she was responsible for killing her best friend Mai's brother Takumi... and her own grandfather]].
** Shizuru also gets a slightly more understated one after [[spoiler:her resurrection in the GrandFinale]], crying openly over the fact [[spoiler:she'd forced her lesbian crush into a TakingYouWithMe situation because she'd gone out of control]]. Not as severe as some, but given Shizuru's graceful serenity over the entire series to that point, seeing her outright crying and apologizing through the tears had impact.
** Yukino after she is blackmailed into [[spoiler:trying to kill Mai]]. Even after the almost victim later thanks her for helping her find [[spoiler:Takumi]], she still feels quite guilty.
** In ''Anime/MaiOtome0Sifr'', Elliot has this reaction after [[spoiler:trying to kill Sifr on Una's orders, thus resulting in Lena being forced to block an attack, leaving her open to M9, and Lena is eventually defeated after overloading her gem]]. After seeing her in tears over it, her companions forgive her, although [[spoiler:Sifr asks if everyone, having withheld information from her all along, wants her dead.]]
* The protagonist from ''VisualNovel/{{Tsukihime}}'' goes through this in every route, after he regains control/consciousness from whatever insanity/inversion/dream-turned-reality he just went through, all of which generally involve him causing bloodshed and death.
* Gyoubu Kasumi from ''Manga/{{Basilisk}}'', after [[spoiler: Tenzen grabs a flautist boy and throws him into the middle of their fight, causing Gyoubu to accidentally kill the boy's father when the old man tries to save his son]].
* In ''Anime/YuGiOh Duel Monsters'', season 4. Yami in a big way after that Raphael duel - [[MoreThanMindControl you]] [[HeroicSacrifice know]] [[WhatTheHellHero the]] [[HeroicBSOD one.]] [[spoiler: In an attempt to win, he plays the Seal of Orichalcos, and when he loses, Yugi offers his soul instead.]]
** Mai, when she snaps out of the Orichalcos' control.
** Noah, in the virtual world filler ark in the anime, about 3 seconds after he enters a helicopter to escape from the nuke he sent himself to destroy the place.
* ''Anime/YuGiOhGX'': Judai's mind is stuck on this trope like a broken record for the first several episodes after becoming acquainted with his SuperpoweredEvilSide.
* Tony in ''TowardTheTerra'' after he [[spoiler:accidentally kills Matsuka, a fellow Mu]], while attempting to assassinate the antagonist. Complete with enough angst to last the rest of the series.
* The manga version of ''ChronoCrusade'' has Chrono do this after [[spoiler:his UnstoppableRage in volume 5]]. He's so distraught he can't even quite get out the words: "Oh, no. Have I done? Ro...sette!"
* In ''{{Papuwa}}'', Kotaro says exactly this when [[spoiler:he remembers that he destroyed the first Papuwa Island]].
* Amuro Ray in ''Anime/MobileSuitGundam'' [[spoiler:shortly after accidentally killing Lalah Sune.]]
* Saji Crossroad in ''MobileSuitGundam00'' [[spoiler:after realizing that his cowardice began a chain of events that resulted in a group of resistance fighters and helpless refugees being massacred at the hands of the ruthless A-LAWS.]]
* Kan'u Unchou in ''IkkiTousen Great Guardians'' after realizing that for a short time she was [[{{Flanderization}} flanderized]] into a PsychoLesbian towards her liege Ryuubi. Then, she tried to kill herself as an atonement, which prompts Ryuubi to [[ArmorPiercingSlap slap her silly]] and tells her to [[GetAHoldOfYourselfMan get a hold of herself]].
* Happens quite often in ''Manga/DetectiveConan'', probably the most memorable one being [[spoiler:a case of a murdered rock star who was poisoned during a little get together. When it's revealed that one of the band mates, who happened to be an jilted ex-girlfriend of his, was the murderer. One of her friends points out that the singer still loved her and reveals so through a postcard with song on the back dedicated to her. The woman breaks down at once she realizes her own foolish action.]]
** [[spoiler:While the girlfriend breaks down crying and screaming Conan gives the memorable quote 'When people build walls around their hearts all that can come out of it is pain and suffering.' It might have nothing to do with the trope but it was in the same episode.]]
* Doctor Marcoh from ''Manga/FullmetalAlchemist''. Now that he's gone and [[spoiler:made the damn Philosopher's Stone already]], he feels horrible about it. With good reason. Also, most of the protagonists in the Ishval arc. War suddenly doesn't seem so great anymore.
** Edward Elric, in an attempt to bring his mother back to life, ends up losing his arm and leg and nearly bleeds to death, his brother's body is completely destroyed and he ends up as a soul in a suit of armor, and then he realizes all he managed to do was create a writhing mass of nightmare fuel instead of his mother. [[ThereAreNoTherapists He really could have used some therapy.]]
** When [[spoiler:Greed kills his only surviving {{True Companion|s}} after being {{Mind Wipe}}d]]. BigNo ensues.
** In [[Anime/FullmetalAlchemist the 2003 anime version]], when Ed kills Greed, the first time he ''intentionally'' killed someone.
*** From the same continuity, Roy after [[spoiler:killing Winry's parents]].
* In ''VisualNovel/HigurashiNoNakuKoroNi'', several of the characters have these moments. Heck, Keichi has two regarding the same horrific event.
** [[spoiler:Shion even ''wets herself'' upon hers.]]
*** [[spoiler:That may be a very, very different kind of wet for all we know]].
* ''[[{{Kikaider}} Android Kikaider: The Animation]]'' (not to be confused with the [[{{Toku}} live-action ancestor]] of the "PowerRangers.") In the first episode, Jiro [[HenshinHero (the android)]] helps some kids get their toy airplane out of a tree by pushing the tree over. (He was in his "human" form at the time, and the kids thought they were enlisting his help to ''climb'' the tree.) After the the kids run away, [[MoodWhiplash any humor in this moment gets a kick in the nuts]] when Jiro realizes there was a bird's nest in the tree, and the eggs in it have been destroyed. In the English dub, he utters the trope verbatim.
* In the manga ''Manga/PokemonSpecial'', Ruby does this when he realizes [[spoiler:he was a huge {{Jerkass}} to his Feebas after she loses a Contest and caused her to run away. He only partly realized that on his own at best, and it takes a [[WhatTheHellHero tongue-lashing from Wallace]] before it finally gets through to him completely.]]
* Meanwhile, in the ''Anime/{{Pokemon}}'' anime, we have the end result of Dragonite's UnstoppableRage in the episode "Great Bowls of Fire", where he flies down to the ground, [[TearJerker picks up a burnt flower, and starts crying]].
** [[Anime/PokemonTheFirstMovie "Fool! Trying to stop our battle..."]]
* In the ''Manga/AsatteNoHoukou'' manga, Amino has this reaction when he finally realizes his actions hurt Karada.
* Shown in ''Manga/TsubasaReservoirChronicle''. While not actually said out loud, it is spoken perfectly clear by the look on [[spoiler:C!Syaoran]]'s face when he looks down at what's left of his loved one, [[spoiler:C!Sakura]], who [[spoiler:he accidentally impaled.]]
** Fai during the Infinity arc [[spoiler:is forced to kill Sakura thanks to his first curse. He then proceeds to lose control of his magic, tear up the arena around him, and nearly commits suicide.]]
*** It gets worse. The Celes arc right after Infinity reveals that [[spoiler: his whole frickin' life is one big ''MyGodWhatHaveIDone'' moment.]] No wonder the guy is an [[BrokenBird emotional]] [[StepfordSmiler wreck]] and wishing for someone to just [[DeathSeeker end it all]].
* ''Manga/{{Bleach}}'': Hitsugaya has this when he and the others attack Aizen and believe that they succeeded, only for the illusion to drop and reveal that Hitsugaya has quite literally stabbed Hinamori in the back.
** Kira has this reaction after he learns [[spoiler:the truth about Aizen's plot, including that his friend Hinamori is in critical condition. He presumably was merely following Ichimaru's orders, and noted that he promised that Hinamori wouldn't get hurt.]]
** Urahara in the "Turn Back The Pendulum Arc" when he realizes that he sent Hiyori into a dangerous situation all alone.
** Don Kanonji when he learns that he had been turning ghosts into Hollows when he thought his exorcism technique had been sending them to Heaven.
** And Ichigo when he [[spoiler: finds that he stabbed Uryu while possessed by a Hollow. Of course, this is cut short when he finds that Ulquiorra is dying as well.]]
* Bisco Hatori's ''Manga/MillenniumSnow'' has the vampire male protagonist, do this after he [[spoiler: grazes Chiyuiki's neck with his fangs, meaning she will have to live for a thousand years with him]] also counts as a WhatTheHellHero moment, as Satsuki promptly tries to kick his ass afterward.
* Mayo Sakaki in the 3rd ''FushigiYuugi'' OVA. When she realizes that her behavior is destroying the universe (and herself), and that love and obsession aren't the same after talking with Houki, she is DrivenToSuicide and attempts to drown herself, believing herself to be beyond redemption.
* ''LightNovel/ACertainMagicalIndex''. After crossing the MoralEventHorizon and getting defeated by Touma, Accelerator notices that his selfish ideals to get his own peace have twisted his mind and taken more than 10,000 innocent people's lives. He tries to redeem himself by saving people for first time in his life but... BANG! he gets a bullet in the brain. [[RedemptionEarnsLife He survived but at the cost of most of his powers]].
** In the novel, Last Order claims that Accelerator never liked the killing of 10,000 sisters experiment in the first place and the reason why he acts so cruel to them is to discourage the remaining sisters from going after him.
* ''Manga/ACertainScientificRailgun''. Kiyama Harumi has this, after [[spoiler: the subjects of one of the experiments she participated in (children in her school class) fell into comas and the head scientist of this program put a gag order in effect and was more concerned about the data then about the children. Later, she found put that the experiment was deliberately dangerous.]]
* In ''Manga/JoJosBizarreAdventure Part 2'', Strohiem has this reaction once the "Ultimate Life Form" (Satanna) escapes from what he thought was an inescapable cell, and proceeds to start slaughtering every single Nazi in the base.
* The title character of ''NadiaTheSecretOfBlueWater'' has a look like this toward the end of Episode 20, after taking a bath with Electra where she learns that she had misunderstood Jean's friendship with Electra. Earlier, she had been quite nasty to Jean ([[GreenEyedMonster in a fit of jealousy]]) when he attempted to compliment her (as advised by Electra). She later learns that Electra only considers Jean as a brother, and feels quite remorseful for her hair trigger outburst at him. (The same is true in that episode when she realizes, again from her talk with Electra, that she has misjudged Nemo and the ''Nautilus''.)
* In the final episode of ''TenshiNiNarumon'', [[spoiler: after Silky sets their wings on fire, Mikael snaps out of his madness and when Raphael appears before him and confronts him with what his actions have led to, Mikael breaks into [[TearsOfRemorse tears]], expresses his remorse over what he has done and pleads his teacher to rescue everyone. When Raphael disappears, Mikael just resigns to the [[RedemptionEqualsDeath worst]].]]
* In the movie version of ''Anime/MagicalGirlLyricalNanoha'', Precia gets one over how she had treated Fate when she remembered that [[spoiler: Alicia had always wanted a little sister.]] Unfortunately, by the time she remembers this, it's too late to apologize or make amends.
* [[MadScientist Van Argeno]] from ''BloodPlus'' when he witnesses the results of his research turn members of the public into Chiropterans.
* In ''Manga/InuYasha'', [[TheStoic Sesshoumaru]] had one of these [[InnerMonologue moments]] in the Underworld upon [[NotSoStoic realizing]] that [[MoralityPet his beloved Rin]] was dead as a result of his quest to strengthen [[HealingShiv Tenseiga]]. "She can't be saved?... What's the point of it now? Tenseiga... Just for something like this, I let you die... To obtain this in exchange for Rin's life - [[CharacterDevelopment it means nothing]]." [[DeathIsCheap She]] [[CrowningMomentofHeartwarming got]] [[TearJerker better]].
* [[spoiler:Keito Nichi]] in ''StarDriver'' when she realizes that [[spoiler:by trying to manipulate and backstab Head, she has actually doomed Sugata to either death or eternity as Head's slave. She was trying to make it so he could rule the world out of her love for him.]]
* In ''Anime/{{Monster}}'', after seeing all of the death and despair caused by Johan Liebert, Franz Bonaparta breaks down completely, feeling guilt for being the man who made Johan into the monster that he is.
* In ''Manga/{{Tsukigasa}}'', Azuma, upon having a drunken illusion of his LoveInterest, Kuroe, being his [[CreepyUncle rapist uncle]], cuts Kuroe's arm off. He goes into HeroicBSOD mode almost immediately over it.

* Jinbe from ''Manga/OnePiece'' expressed guilt for letting his hatred for humans get the best of him and he wound up indirectly letting Arlong to go to East Blue and terrorize Nami's village for years. He felt quite ashamed of this and offered to accept any punishment Nami wanted to give him.
* Applies to Jeremy in ''Manga/ACruelGodReigns'' after he [[spoiler: accidentally kills his mother along with Greg by VehicularSabotage in a MakeItLookLikeAnAccident]].
** Can also apply to Ian when Jeremy finds [[spoiler: the pictures Greg took of him after whipping/raping him that Ian kept.]] Jeremy, as expected, reacts negatively and has a FreakOut, which leads to Ian's MyGodWhatHaveIDone.
* In ''Manga/BlackLagoon'', Roberta reacts like this after [[spoiler: she blasts GARCIA, of all people, in an instinctive trigger-pull near the end of El Baile de la Muerte.]]
* In ''Anime/GundamWing'', Heero is overcome with this after destroying an airplane carrying what he believed to be senior members of the OZ organization. Then Wufei arrives and tells them that he just actually killed all of the senior leaders of the United Earth Sphere Alliance who wanted to make peace with the space colonies. It was then everyone realizes they'd just been suckered into MagnificentBastard Treize's BatmanGambit; it was also then when they realized [[GreyAndGrayMorality this was not a black-and-white war]].
* In ''Manga/SayILoveYou'', Yamato starts to realize this when Aiko [[WhatTheHellHero calls him out]] on the rumor that he was seen leaving Megumi's apartment. She tells him that Mei, his girlfriend, was deeply hurt by that rumor. He initially doesn't think there's anything wrong with it, since he states there's nothing going on between them, and he's simply going there for dinner. Aiko then asks him that if the situation were reversed, where Mei was going to another guy's house without his knowledge, if Yamato would be okay with that. He runs off and begins searching for Mei, canceling his photo shoot with Megumi in the process.
* ''Manga/KotouraSan'':
** Hiyori suffers this after she [[spoiler:arranges for thugs to beat up Manabe for choosing Haruka over her. The encounter doesn't go as planned, ending up with Manabe getting injured - stabbed in the manga and sorely beaten in the anime - and sent to the hospital.]] She then suffers HeelRealization about how much of a {{Jerkass}} she's been.
** For the ''same incident'', Haruka also believes she's the cause of all the strife between Manabe and Hiyori for the latter's [[ClingyJealousGirl jealousy.]]
* Ellen in ''Anime/SuitePrettyCure'' suffers this first hand as she watches a boy she had accidentally convinced to continue run away and his father be struck with a Negatone's wail, pushing them into despair. Bassdrum points out that ''she'' had done this so many times and, driven to despair herself, tosses away her Cure Module. However, Hummy's there to get her to realize that, deep down, she ''wants'' to make up for those times and helps restore her HeroicResolve.
* Several characters in ''Manga/AttackOnTitan'', due to the [[CrapsackWorld dark]] nature of the series.
** Jean is horrified by his own actions, after successfully leading the other trainees to safety. Not only did people die on his [[TheChainsOfCommanding command]] trying to reach headquarters, but he intentionally used the deaths of other comrades to pull the whole thing off.
** [[spoiler:Titan [[TheMole agent]] Annie is so horrified by the aftermath of the attack on Trost that she can only stand there in shock, apologizing to what might have been her friend's corpse.]]
** [[spoiler:Reiner, another [[TheMole Titan agent]], is so overwhelmed with guilt over his actions that he begins [[BecomingTheMask repressing his memories]] and [[VillainousBSOD breaks down]] completely once he admits to everything.]]
** In stark contrast to the previous two, [[spoiler:Bertolt, the third [[TheMole Titan agent]], initially shows no remorse for his actions. Even being reminded by Eren that he is directly responsible for Eren's mother's death (a piece of the Wall he kicked crushed her legs so she couldn't escape the Titans) garners no emotional reaction from him beyond admitted pity. Later when confronted by the rest of his former squadron comrades he breaksdown and admits he hates what he's done and did come to care for his friends.]]
** Both [[TheStoic Levi]] and [[MadScientist Hange]] experience a brief moment of this [[spoiler:when they find out Titans are actually transformed humans.]]
* In ''Anime/FinalFantasyTheSpiritsWithin'', this is [[GeneralRipper General Hein]]'s reaction when a minor FalseFlagOperation he ordered escalates into an all-out invasion of major population center by the Phantoms. He even contemplates suicide for a bit, before deciding to [[FromBadToWorse finish the job]].
