One of the most devastating {{Awful Truth}}s a character can recieve.

''"You caused the death of your friend/parent/mentor."''

Often a WhamLine, there is no more reliable way to send a heroic character [[HeroicBSOD spiralling into grief]] than to reveal that they were responsible for the death of someone close to them. The surprise element is the important part here; the character has hitherto been living perfectly happily and innocently, completely oblivious to what they've done. Common consolations include telling the character that obviously, its not their fault if they weren't even ''aware'' of the damage they were causing, but this is often of little comfort to the stunned recipient.

Telling someone this with the direct intention of hurting them is [[KickTheDog one of the cruelest things any character can do]]. Doubly so if they're telling BlatantLies.

Subtrope of NiceJobBreakingItHero sometimes. See also SurvivorsGuilt, YouShouldHaveDiedInstead, and FailureToSaveMurder, all of which can also be present.

'''This is a subtrope of TheReveal. Not to mention a [[DeathTropes Death Trope.]] Expect MASSIVE spoilers!!!'''

[[folder: Anime and Manga ]]

* In ''Manga/{{Btooom}}'', Ryouta applies this trope to himself when he realizes [[spoiler: Taira's death]] was largely because he seemingly ignored other people's thoughts and feelings, as well as [[ItsAllAboutMe doing whatever he wanted to do.]] As a result, his friend started going insane due to his injuries, which ultimately led him to attack both Ryouta and Himiko when he starts to hallucinate about his family and meeting them again.
* In episode 16 of ''Anime/CodeGeass'', [[PsychopathicManchild Mao]] calls out Suzaku for the death of his own father, Genbu Kururugi.
** In episode 12, Shirley tells Lelouch about her father's death during the previous episode when the Black Knights, which Lelouch leads as his alter-ego Zero. During the fighting there, he was one of the casualties of the battle. [[MyGodWhatHaveIDone Made more painful]] to Lelouch when she tells him that her father wasn't a JerkAss, and was actually a caring person who loved her very much.
* Though it wasn't intentionally directed at her, Claire Cruz in episode 4 of ''LightNovel/ToaruHikuushiENoKoiuta'' is GenreSavvy enough to piece together the events that Kal-el tells her about his past to realize that [[spoiler:as her alter ego, Nina Viento, she was indirectly responsible for causing the overthrow of his royal family during a rebellion a few years earlier, and subsequently their deaths.]] She's shocked enough by this to be uneasy around him for the rest of the episode, and partly into the next one as well.

* in the ''{{Series/Emergency}}'' fic [[''http://audreys-efanfic.freeservers.com/lostandfound.html Lost and Found]]'', John's captor torments him this way. Roy was his original target, but John begged to be taken instead, to spare Roy. Roy is shot, but survives. However, John's captor lies and says Roy died and suffered and would have lived if not for John's actions.
* In ''Fanfic/NecessaryToWin'', this is said practically word for word by [[spoiler:Teru, to Saki]]. On the other hand, someone close to the speaker doubts whether she actually truly believes this.
[[/folder]]

[[folder: Film - Animated ]]

* In ''Disney/TheLionKing'', right after killing Mufasa, Scar tells Simba that he's responsible for Mufasa's "accidental" death. Much later, [[JustBetweenYouAndMe rescinding his lie]] was one of his last mistakes.
** They did it again in ''The Lion King 2: Simba's Pride''. After watching Nuka try to climb an unstable log dam after Simba and subsequently fall to his death, Zira turns on Kovu, claws him across the eye, and snarls, "Nuka is dead because of ''you''. [...] You've killed your own ''brother''!"
* This happens in ''Disney/{{Frozen}}'' when [[spoiler: Hans tells Elsa she killed her sister with the intent of getting her to cross the DespairEventHorizon so that he can finish her off. He's lying in that Anna's not dead yet that that point, but she does freeze to solid ice a few moments later as a result of the freezing curse Elsa (accidentally) put on Anna, but is saved by the act of love she performs to save her sister]].

[[folder: Film - Live Action ]]

* Not directly said, per se, but it seems in ''Film/TwentyEightWeeksLater'' that the kids realized that they were a tiny bit responsible for the events that tossed the big pile of fecal matter into the air circulation device, leading to the death of just about everybody but them.
* ''StarWars: RevengeOfTheSith'':
-->'''Darth Vader:''' Where is Padme? Is she safe? Is she alright?\\
'''Darth Sideous:''' [[ExactWords It seems]] in your anger, you killed her.
* In ''Film/{{Memento}}'', the main character eventually finds out from Tommy that his wife was a diabetic and that the story he made up about "Sammy Jenkis" killing his wife by giving her too much insulin was actually a self-protecting projection of what he did.
* ''Film/ShutterIsland'': [[spoiler: Leonardo [=DiCaprio's=] character's family is dead because he ignored his wife's mental illness and when she murdered his kids he killed her then "imagined" that he was looking for his family's real killer. It's implied this truth is so horrible that the ''second'' time he realized it he chose to get a lobotomy instead of living with what he's done.]]
* In the big battle scene in the middle of ''Film/{{Kagemusha}}'' one of the retainers points at a number of corpses of young Takeda samurai and tells Kagemusha (impersonating Shingen Takeda): "These men died to defend you."

[[folder: Literature ]]

* ''Literature/HarryPotter'' pulls this a number of different times.
** It happens twice regarding Harry's parents; first when Harry discovers that Peter Pettigrew sold them out and second when he learns that Snape told Voldemort about the prophecy in the first place, not counting when Harry yells it at Sirius falsely believing him to be the traitor.
** When Sirius is killed Harry blames himself for causing Sirius to put himself in danger and not listening to Hermione and forgetting Snape, Dumbledore for not explaining stuff to Harry and keeping Sirius cooped up, Snape for not being especially helpful and mocking Sirius about being useless, and Kreacher for locking Sirius in his room and lying.
** At the end of the series, Harry blames himself for everybody's deaths as they did, essentially, die in his name.

[[folder: Live Action TV ]]

* Attempted by Rose in ''Series/DoctorWho'' against the titular Dalek. Doesn't work, because, well, it's a Dalek.
-->'''Rose''': They're all dead because of you!
-->'''Dalek''': THEY ARE DEAD BECAUSE OF '''US'''!

[[folder: Video Games ]]

* In ''[[VisualNovel/PhoenixWrightAceAttorney Phoenix Wright: Ace Attorney]],'' Manfred von Karma tries to convince Miles Edgeworth that he (accidentally) killed his father, Gregory Edgeworth, by getting angry and throwing a gun that went off and hit him.
** In the third case of the second game, a variant of this happens when Regina is forced to face the fact that her DeadlyPrank was why Bat went into a coma.
** In ''Trials and Tribulations'', Godot tells Phoenix that he was responsible for Mia Fey's death, and that he himself could have prevented it.
* In ''VideoGame/DragonAgeII'', Merrill's Act III personal quest ends with this. Anders and Fenris [[YouShouldHaveDiedInstead remind her cruelly of this]].
* In ''VideoGame/FinalFantasyII'', if you go back to Altair and speak to Hilda after getting Gordon in your party the first time, [[TheDevTeamThinksOfEverything there is special dialogue]] between the two, where Hilda is infuriated with Gordon, saying that his cowardice caused Josef's death. To elaborate, they needed to get inside Kasuon Keep for a special torch, and the only way of entrance is either with a certain bell or the voice of a member of the royal family. On the mission to get the bell, the party encounters Borghen on the way out, and Josef pulls a HeroicSacrifice to save them from a boulder trap; the implication is that this all could have been avoided if Gordon had helped them.
* Certain game-over conditions in ''NightTrap'' cause the MissionControl commander to blame [[WhatTheHellPlayer the player]] for the deaths of the heroine and the other victims.
* In certain missions during the various ''VideoGame/CallOfDuty'' games, especially the ones that rely heavily on stealth, if you attract unwanted attention, say by shooting at a platoon of enemy soldiers instead of letting them pass you by undetected, you'll probably get a NonStandardGameOver, either by you getting killed by the overwhelming firepower, or your ally gets killed in the event you somehow manage to outfight/outrun them. The game makes sure to tell you caused their death.
* In ''VisualNovel/SuperDanganRonpa2'', [[JerkAss Saionji]] tells Kuzuryuu that because he played the game that was Monokuma's "motive," he caused the deaths of Saionji's best friend, and Kuzuryuu's childhood friend and bodyguard; the latter killed the former while believing herself to be carrying out his will, and was executed for it. Kuzuryuu agrees, then attempts {{Seppuku}} as penance.

[[folder: Web Comics ]]

* ''Webcomic/GunnerkriggCourt'': Delivered in a devastating, defensive rant by [[spoiler: Rey to Annie about why none of the psychopomps came for Annie's mother; Annie had been unknowingly draining her mother's lifeforce as she grew older until there was 'nothing left to take' to the afterlife.]] The effect is instantaneous, and doubles as a WhamLine.
* In ''Webcomic/UniversalCompass'', Two's sadness parallel tells her she died because Two died. This trope has the potential to happen to every character because the empty parallel and emotional parallel's lives are linked.
