** In addition [[RapePillageAndBurn to his brutal actions during war]] and SerialKiller nature, Gregor Clegane is established as a horrible person early on when Littlefinger reveals his brother Sandor's face is burned because Gregor tried to kill him by holding him in a fireplace [[DisproportionateRetribution for playing with his toy]]. It's also heavily implied he murdered his sister and his father for the inheritance.

* ''Literature/TheBible'':
** Cain is known as the father of murder after he kills his younger brother Abel. God marked him so anyone who encountered him would know that Cain is to be shunned and that murdering him will encounter punishment from God, as Cain is intended to live a long life of shame as punishment for his crime.
** Subverted with Abraham and Isaac. God asks Abraham to sacrifice his only son, knowing that in addition to the grand taboo around kinslaying, Abraham and Sarah prayed for decades for a son and considered Isaac their miracle baby. The sacrifice is a test of Abraham’s faith and love for God. When Abraham moves to do as asked, God stopped Abraham and sent a ram to be slaughtered instead.

* Zigzagged in ''Fanfic/TheRavensPlan''. For those who don't [[PeggySue Remember]] or died early in the previous timeline, this is played straight. For everyone else, each case is judged by the circumstances surrounding it.

** Another straight example is Randyll Tarly threatening to kill his son Samwell if he didn't take the Black. As it turns out, ''none'' of their family were aware of that threat -- the moment they found out, a furious Melessa gave Randyll a slap and a short, brutal ReasonYouSuckSpeech, while his favorite son Dickon spurned him and sided with Sam during his coup against Randyll. Later on, when Talla visits him during his house arrest, Darvon refuses to leave her alone with him because he can't trust him not to try and harm her like he did with Sam.
** Old Walder Frey was murdered by his sons Raymund and Aenys. Stevron Frey considered it a deed evilly done, and both Brynden Tully and Patrek Mallister considered it another line crossed. Edmure Tully, Jonos Bracken and Tytos Blackwood [[BlackComedy simply thought it was hilarious]].

* ''VideoGame/BatmanArkhamAsylum'': At one point, the player can hear various mooks discussing what Joker required them to do in order to join his gang. One guy says that Joker instructed him to kill his sister, which he did as he always hated his sister. Another guy says that the Joker kept telling him the same thing, even though he didn't have a sister; so he just killed some random woman. [[ForTheEvulz Joker approved.]]

* In ''Anime/SpaceRunawayIdeon: Be Invoked'', Harulu murders her pregnant younger sister, Karala, by shooting her in the head ''three times''. She did it out of jealousy because she gets to have a child with the man she loved while she lost her lover during the war. It doesn't help that their father approves it because Karala's reckless actions brought shame to their family. Unfortunately, the death of Karala and her unborn child set the tide where [[KillEmAll Ideon begins its invocation to eradicate all life in the galaxy]].

* ''Fanfic/JWITCHSeason1'': Multiple characters are horrified to learn about the rumor that Phobos murdered his own parents, and though this rumor is [[FrameUp false]], it was a large part of the reason the majority of Meridian's inhabitants didn't accept him as their new ruler. Notably, Phobos makes a point of telling Cedric in certain terms that he won't murder his little sister once he no longer needs her, [[EvenEvilHasStandards for he doesn't want to become the kinslayer he's believed to be]].

** Played with concerning Stannis Baratheon. He kills his brother Renly Baratheon through dark magic. However, Renly was the younger brother who was trying to usurp the throne himself basically through [[MightMakesRight having a bigger army]] than anyone else and clearly intended to kill Stannis for not submitting to him, showing no remorse at this. By contrast, Stannis after his brother's death is distraught.

** Both Randyll Tarly and Tywin Lannister have tried [[LoopholeAbuse to get around the taboo]] so they can get rid of [[TheUnFavourite the son they hate the most]], Samwell Tarly and Tyrion Lannister respectively. Randyll threatens Samwell by saying he'll be involved in a HuntingAccident, while Tywin hopes Tyrion will get himself killed in battle. Tywin's hatred of Tyrion stems from considering him a kinslayer as [[MaternalDeathBlameTheChild his mother died giving birth to him]]. Eventually, he fingers Tyrion for King Joffrey's murder in hopes he'll get executed, [[LaserGuidedKarma leading to Tyrion becoming an actual kinslayer]] [[{{Patricide}} by shooting him with a crossbow in retribution]].

** Euron Greyjoy has contempt for the Ironborn traditions, including this trope. He killed his half-brothers Harlon and Robin, is heavily implied (and later outright confirmed) to be behind [[spoiler:his full brother Balon's death]] and wants to kill his full brother Victarion. He uses the fact that [[KarmaHoudini the gods have yet to punish him for it]] as proof the taboo against kinslaying doesn't mean anything. His disregard for traditions and his kinslaying are the main reasons the rest of his siblings despise him.

* In ''ComicBook/TheSandman'', [[TheHecateSisters the Furies]] are feared by everyone from supernatural beings to gods to [[AnthropomorphicPersonification The Endless]] themselves. Once loosed on a target, the Furies will hound them and destroy everything they care about until either they kill their target at the end of their rampage or their target hits the DespairEventHorizon and kills themselves. However, the Furies only hunt those who committed an act of kinslaying. [[spoiler:Unfortunately for Dream, even a MercyKill can be used to invoke them.]]

A SubTrope of MurderInTheFamily. {{Matricide}} and OffingTheOffspring are the most likely familicide types to use this trope because of how love for one's mother [[EvenBadMenLoveTheirMamas is often used as a redeeming trait for a bad guy]], and the fact that [[WouldHurtAChild killing children]] is seen [[MoralEventHorizon as especially heinous]], though some examples manage to avoid this trope [[SympatheticMurderer by giving the killer a justified reason]] for it.

** In the Season 6 finale, Cersei Lannister herself not only kills her enemies, [[spoiler:the Faith Militant and the Tyrells]] but also [[spoiler:her uncle Kevan and her cousin Lancel]] with wildfire at the Sept of Baelor. She has no concern about who died. In her mind, all of those who opposed her in King's Landing are gone now. However, the facts that Margaery Tyrell died in the conflagration and that this incident proved he was just a PuppetKing drive Cersei's son Tommen to suicide, which she's less happy about.

** In the Season 6 finale, Cersei Lannister herself not only kills her enemies, [[spoiler:the Faith Militant and the Tyrells]] but also [[spoiler:her uncle Kevan and her cousin Lancel]] with wildfire at the Sept of Baelor. This indirectly drives Tommen to suicide. She has no concern about who dies. In her mind, all of those who opposed her in King's Landing are dead.

** As further evidence that this series' version of [[spoiler:Dudley Dursley]] is [[AdaptationalVillainy significantly more evil than his canon counterpart]], [[spoiler:he arranges the murder of his parents, Vernon and Petunia, to remove any traces of his Muggle parentage and make him register as a Pureblood so that he can join the Death Eaters. Needless to say, doing this erases any pity the reader may have felt for Dudley when Sirius Black savages him to death in dog form.]]
** Subverted with [[spoiler:Draco Malfoy when he pulls a KillAndReplace on his father Lucius Malfoy to infiltrate the Death Eaters. Draco is ''not'' on good terms with his father in the Dangerverse, due to Lucius constantly threatening his loved ones and attempting to brainwash Draco back to the fold. So he's done the heroes a favor by getting rid of Lucius.]]

* ''Fanfic/TheMountainAndTheWolf'': As payment for bodyguarding Tyrion against Bronn, the Wolf demands Bronn's crossbow (which Tyrion had used to murder his father). Tyrion doesn't really see why, but the Wolf says repeatedly using a weapon for a specific crime makes it stronger. Tyrion doesn't pursue the matter, glad the Wolf isn't damnding more gold on top of it.

** Euron Greyjoy has contempt for the Ironborn traditions, including this trope. He killed his half-brothers Harlon and Robin, is heavily implied (and later outright confirmed) to be behind [[spoiler:his full brother's death]] and wants to kill his brother Victarion. He uses the fact that [[KarmaHoudini the gods have yet to punish him for it]] as proof the taboo against kinslaying doesn't mean anything. His disregard for traditions and kinslaying are the main reasons the rest of his siblings despise him.

** The wildling women sent with Mance Rayder by Jon Snow and Melisandre to rescue the girl they think is Arya Stark (actually Jeyne Poole) denounce Theon Greyjoy as a kinslayer since he supposedly killed Bran and Rickon Stark (although it was actually two other, equally innocent boys). Theon's not actually related to Bran and Rickon, but being Ned Stark's ward/hostage makes them effectively foster brothers.

** Played with and subverted with Tyrion killing Tywin. Normally that would be another mark against Tyrion, but Tywin's ZeroPercentApprovalRating means no one outside of Casterly Rock really cares, especially since Tyrion and Jaime supported the Targaryens in combating the Second Long Night. Inside Casterly Rock, the only people unnerved by it are Tywin's siblings, and even they supported Tyrion's coup in the end, because even they couldn't deny that Tywin had effectively screwed over the entire family with his ruthlessness.

** Other examples include Lycaon (the first werewolf, punished for making a stew of an infant who may have been his own grandson depending on the version), several instances of the House of Atreus (descendants of Tantalus above), Medea and the story of Philomela and Procne (the two women served up the son of Procne to the boy's father and Procne's husband because the husband raped Philomela, Procne's sister, then tore out her tongue so she won't be able to tell. When he found out and tried to kill them, they all got turned into birds).

** Although King T'Chaka was greatly beloved throughout his life, his legacy is tarnished when it is posthumously revealed that he murdered his own brother for what he thought was the greater good and abandoned his nephew to grow up in poverty, never knowing his royal Wakandan heritage. T'Challa is completely shaken to learn the truth about his father and gives T'Chaka one hell of a TheReasonYouSuckSpeech when he confronts him on the ancestral plane for the second time.
** It is cemented that Killmonger is a hateful character by how gleeful he is at the opportunity to kill T'Challa, his cousin who has personally never done anything wrong to Erik. Whenever T'Challa engages in ritual combat, he always gives his opponents, including Killmonger, multiple opportunities to yield rather than be killed. Killmonger takes obvious pleasure in throwing T'Challa off the mountain to his apparent death.
** Averted in T'Challa and Killmonger's final fight. The juxtaposition between the two characters is shown when T'Challa offers to get Killmonger the medical care needed to save his life when Killmonger is mortally wounded in their fight.

** Late in the game, it is revealed that [[spoiler:Barbaneth Beoulve]] did not die of illness, but was poisoned by his eldest son. The killer's brother is outraged by the action, and calls the murderer out on it, saying that it's worse than even the latter's killing of their liege lord.

* ''Literature/ASongOfIceAndFire'': Kinslaying is seen as one of the two worst crimes someone in Westeros can commit, the other being violating [[SacredHospitality guest right]]. Even [[TheSociopath Roose Bolton]], [[spoiler:who participates in [[NastyParty the Red Wedding]] ]], refuses to kill off [[AxCrazy his psychopath of a son]] ([[StupidEvil despite the trouble his open sadism causes]]) because of this taboo.

* In ''VideoGame/FinalFantasyTactics'', late in the game, it is revealed that [[spoiler:Barbaneth Beoulve]] did not die of illness, but was poisoned by his eldest son. The killer's brother is outraged by the action, and calls the murderer out on it, saying that it's worse than even the latter's killing of their liege lord.

** Light reaches new levels of depravity when he contemplates killing Sayu, his own sister, to protect his secret, only relenting because of the scrutiny it would draw. While he doesn't directly kill his father, he still has no regrets over being responsible for his death at Mello's hands and later [[SpeakIllOfTheDead dismisses him]] as an idealistic fool.
