Sometimes even the Hero gets utterly frustrated by a particular race or person, to the point that the race or person may face a horrible extinction or other horrible fate, and the Hero is just too jaded or disillusioned to care, usually by having been personally wronged by the race/person in question to a horrible extent, most often involving family or a friend having been killed by said race or individual's actions. Sometimes it is accompanied by a speech, sometimes it is just those three small, but powerful and life-changing (or life-ending) words. This trope often results in a WhatTheHellHero moment, or at the very least a long, often loud objective lecture. Often the result of a MomentOfWeakness.

This trope is USUALLY applied to the Hero, but not always. However, the ones delivered by the hero are almost always the ones that get the most fervent objections from friends, or sometimes even change who was perceived as the hero into an AntiHero at best, or the BigBad at worst. For deliberately arranged examples see MurderByInaction and DoWithHimAsYouWill.


[[AC:Comic Books]]
* ''ComicBook/GreenLantern'' Sodom Yat hated the xenophobia of his homeworld Daxam. It reached a peak in his childhood when he befriended an alien named Tessog that had crashlanded on Daxam. Sodom's parents ''brainwashed'' Sodom and murdered Tessog. Sodom realized the truth after seeing his friend's stuffed corpse in a museum. He repaired his friend's ship vowing to leave the planet forever when the Green Lantern ring appeared and gave him another out. Years later, when the Sinestro Corp attacked Daxam, Sodom seriously considered leaving the planet to its fate.

* The TropeNamer is ''Film/{{Star Trek VI|The Undiscovered Country}}''. Kirk is infuriated to find he has been nominated to extend "the first olive branch" of peace to the Klingons, who can no longer afford to maintain hostilities with the Federation. Kirk has hated the Klingons outright ever since [[ItsPersonal they killed]] [[Film/StarTrekIIITheSearchForSpock his son]] and when Spock attempts to persuade him that it's the right thing to do he names the trope.
** Incidentally, originally Kirk was supposed to immediately recoil in shock at his own bloodthirsty outburst before amending "I didn't mean that", but it was cut. Apparently William Shatner was quite annoyed at the ommission.
* During the Normandy assault on ''Film/SavingPrivateRyan'', a soldier gets behind the German bunker and sets it ablaze with his flamethrower. One of the soldiers on the beach sees the Germans jumping off the side of the bunker on fire and orders the others not to shoot, but "let them burn".
* ''Film/BatmanBegins'' sets the condition that Batman will not kill a human. During the climax, Ra's Al Gul says he'll never stop trying to destroy Gotham, while on a speeding train headed towards Wayne Tower. Batman says he won't kill him, but he ''doesn't have to save him either'' and BASE jumps off the train.

[[AC: Literature]]
* In ''Literature/ASongOfIceAndFire'' many people counsel the Lord Commander of the Night's Watch to abandon the wildlings behind the Wall to be killed by the Others, due to the difficulty of saving them and their historical status as enemies of the Night's Watch. During one attempt to convince them why this is not a good idea, he points out that the Others raise the dead, and they're proposing giving their enemy thousands of soldiers.
* In ''Literature/DragonBones'', Ward is asked about how his plan will affect his uncle. (As things are, his uncle could be killed by the villains). He, sarcastically, replies that the death of his uncle is just what he needs, now. To his shock, Oreg actually ''believes'' him, and is angry at him for the next few days, until Ward can bring himself to talk about the topic again. This trope is played straight earlier, when the nobleman Landislaw comes to him and wants help in recapturing a slave he lost, and who doesn't belong to him, and whose disappearance could cause Landislaw to be killed by the disgruntled owner. Ward says he doesn't care, slavery is wrong, and he never liked Landislaw anyway.
* In ''Literature/{{Masques}}'', the heroes are in a kind of rebel camp, and there are two nobles who are pretty useless and only cause problems. They jokingly discuss the option of feeding those nobles to a dragon (they're male and their virginity is questionable, but it may be worth a try), or let them be eaten by the undead abominations. Or just fall down a hole in the caves the rebels are hiding in. They don't do any of those things in the end, as, after all, they're still the heroes.
* In ''Literature/{{Sphere}}'', Norman decides to abandon Beth and Harry to their fate by rationalizing how much trouble they've become and how their fears have almost killed him. It's only when he realizes that he's manifesting his own worst fear, the fear that he doesn't care about anyone besides himself, that he turns back and saves them.

* "[[Series/{{Angel}} And yet somehow, I just can't seem to care.]]"
** Doubles as an IronicEcho since the villain pleading for help said the exact same thing when asked about all of the suffering he and his compatriots cause on a daily basis.
* ''Series/BreakingBad'' has Walter White let Jane die when she vomits in her sleep from a heroin overdose.

[[AC:Video Games]]
* For most of ''VideoGame/MassEffect1'' the Council has mocked you, questioned you, and otherwise screwed you, [[spoiler:even colluding with Udina to ground your ship on the Citadel]]. At the climax, you have the option to [[spoiler:leave the Citadel fleet and the Destiny Ascension to be annihilated fighting the Geth fleet, allowing the Alliance to ride in and mop up the remnants and take down Sovereign.]] The dialogue tree option literally says, "Let the Council die!" Later, a renegade Shepard has the option to claim he/she was waiting for a chance to get rid of them all along, prompting a shocked response from Anderson and a smug response from Udina.
** [[spoiler:This option also causes 10,000 people to die, and can result in worsened relations between humanity and the other Council races]].
** For a more individual-oriented example, in ''VideoGame/MassEffect2'' on [[spoiler:Jacob's]] loyalty mission you have to option to leave [[spoiler:Acting Captain Taylor]] to be presumably maimed and killed by his feral crew. Why? He set his mechs on you and his crew, brainwashed several of them to be mindless guards, forced most of the crew to worship him like a god, and [[spoiler: passed around the female crewmembers like sex slaves between officers]]. His abuses are so unacceptable [[spoiler:his own son recommends you kill him or leave him to die.]]
** In the third game, the Renegade method to [[spoiler:achieve peace between the geth and quarians]] is to tell [[spoiler:the quarians]] that you're sick of helping them out like you did in the past, and that if they [[spoiler:attack the soon-to-be-upgraded geth]], they will die and you will not stop it; they will then get the hint and abandon the attack. This option does, however, require a fair bit of preparatory choices going back as far as Mass Effect 2 to be available (as is the more Paragonic alternative to reconciling the two sides).
* In ''[[VideoGame/ModernWarfare Modern Warfare 3]]'', you came across a prisoner who's going to be executed by the militias, in order to maintain your low profile in a stealth mission, it is wiser to remain silent and let him die. You may try to save him but he'll immediately be killed by the militias and your cover will be blown.

[[AC:Web Comics]]
* Acheron says this of the elves in ''Webcomic/{{Inverloch}}'' when--after it becomes clearer and clearer that elven society is isolationist, arrogant, selfish, and hypocritical--he learns that [[spoiler:his father was killed by an elf for the offense of... being mad that the elves had reneged on their word to protect the da'kor]]. Lei'ella, an exiled elf who's herself pretty disgusted with them, delivers a WhatTheHellHero for his willingness to let the ''entire'' race die (including the girl he undertook the quest for in the first place) just because the ones in charge are terrible. [[spoiler:In the end, the elves are saved, but are forced to recognize and reform their ways.]]
* In ''Webcomic/TheOrderOfTheStick'', when Elan was captured by bandits, Roy was seriously considering simply leaving him to his fate due to [[TheLoad Elan]] being a complete burden to the party. Later on however, he decided that like it or not, as the leader he shouldn't leave his people to die and joined the rest of the group in rescuing him. [[spoiler:While being judged in the afterlife]], [[WhatTheHellHero he is chewed out for this]]. By this point, he's developed enough that he is genuinely ashamed he ever considered it.

[[AC:Western Animation]]
* In the ''WesternAnimation/JusticeLeague'' episode "Twilight", {{ComicBook/Darkseid}} shows up in the Watchtower and asks for the League's help since Brainiac is attacking Apokolips. Superman's response?
-->'''Superman:''' ''[[OOCIsSeriousBusiness Good.]]''
** Given all that Darkseid put him through, it doesn't really come as a surprise that Superman would act that way. Supes also suspected that Darkseid had an ulterior motive for asking for help [[spoiler:and ultimately turned out to be right]].
