** Banshees are ghosts of elven women slain during Arthas' conquest of Silvermoon, with [[MakeMeWannaShout only their voices left]] to express their hatred and suffering.

* Jason Todd from ''ComicBook/{{Batman}}'' is always a troubled, aggressive child, but he stands by Batman's ThouShaltNotKill code and fights by his side as Robin[[note]]Notable that before this trope kicked in, Batman had his costume enshrined with the placard "A Good Soldier"[[/note]]. Then the Joker kidnaps and brutally murders him during ''ComicBook/ADeathInTheFamily'', and years after that, the events of ''ComicBook/InfiniteCrisis'' cause him to return to life.[[note]]While it was reality warping that did it technically, in 'real life' his corpse was taken and placed in a Lazarus Pit.[[/note]] Jason then adopts the Joker's original identity, Red Hood, and attempts to take over organized crime in Gotham in a ploy to kill Batman's RoguesGallery while also seeking to get the Caped Crusader to finally break his code against killing, by any means necessary. Unlike most examples, he eventually manages to take a few steps back from the brink, though he remains the most radical and prone to trouble of the Robins.

* ''Fanfic/{{Foxfire}}'': The Woman in White was a beautiful woman who fell in love with a much wealthier upper-class man and started a family with him. However, he wanted to marry wealthier women, so he drove her to commit suicide to get rid of her. At first, she only killed people who cheated on their loved ones. When her children are murdered, she starts killing anyone that crosses her path.

* ''Film/{{Ringu}}'' has Sadako Yamamura, at least in her original backstory. Born with immense psychic powers she couldn't control, she attempted to lead a normal life before she was raped and tossed into a well to die. Only then did she decide she wanted to bring harm to the whole world. Her western remake incarnation, Samara, gets hit with AdaptationalVillainy and is implied to have been evil in life as well.

* In Creator/StephenKing's ''Literature/PetSematary'', it's strongly {{implied|Trope}} the cursed burial ground has [[GeniusLoci a will of its own]] and arranges Gage's death (hence murdering him), before reviving him as a monstrous parody of a child. In this case, it's the killer (force) that provides the malevolence but is only able to do that once Gage is dead.

* In ''Literature/LockwoodAndCo'', murder victims generally are extremely likely to become violent and dangerous ghosts, because they're so furious and bitter about what has been done to them and desire revenge. In the first book, Lucy weaponises this by [[spoiler:releasing the ghost of Annabelle Ward and letting her destroy her murderer (who was attempting to kill the main cast at the time.)]]

* ''VideoGame/WarcraftIII'':

* In Creator/JunjiIto's story ''[[http://scans-daily.dreamwidth.org/6527013.html#cutid1 The Seashore,]]'' a group of schoolchildren tragically drowned [[spoiler:and seem to be spending their afterlife luring in new people to drown for the sake of killing them]].

* Jason Todd from ''Franchise/{{Batman}}'' is always a troubled, aggressive child, but he stands by Batman's ThouShaltNotKill code and fights by his side as Robin[[note]]Notable that before this trope kicked in, Batman had his costume enshrined with the placard "A Good Soldier"[[/note]]. Then the Joker kidnaps and brutally murders him during ''ComicBook/ADeathInTheFamily'', and years after that, the events of ''ComicBook/InfiniteCrisis'' cause him to return to life.[[note]]While it was reality warping that did it technically, in 'real life' his corpse was taken and placed in a Lazarus Pit.[[/note]] Jason then adopts the Joker's original identity, Red Hood, and attempts to take over organized crime in Gotham in a ploy to kill Batman's RoguesGallery while also seeking to get the Caped Crusader to finally break his code against killing, by any means necessary.

[[folder:Fanfic]]

* This gets applied to the titular Doctor of ''Series/DoctorWho'' in the episode "Hell Bent" after the events of "Heaven Sent". [[spoiler:After being killed and cloned in a cycle for several billion years, the Doctor deposes the government responsible and begins to abuse time travel technology to try and prevent a friend's death in a way that threatens the entire space-time continuum.]]

** In "Right To Die", Cliff sabotages his car so that his wife Abbey [[spoiler:(who was actually pregnant)]] will go into a coma, then he performs euthanasia on her. Suffice to say, she was friggin' ''pissed'' and refused to move on.
** In "Dream Cruise", a Japanese ghost is haunting a specific sea area and attacking any ships who come near as a result of having been murdered by her unfaithful husband.

** "Dead in the Water" has Peter Sweeney, who was accidentally drowned by two of his childhood bullies. Over the next 35 years, his VengefulGhost enacted a brutal RevengeByProxy, killing those bullies' loved ones until the last surviving bully offers his life to lay the ghost to rest.
** Ghosts usually succumb to SanitySlippage, especially since UnstoppableRage helps them affect the physical world. After [[spoiler:Bobby]] is murdered, he slowly becomes more driven to attack his killer and less concerned about the well-being of others, until he has his HauntedFetter destroyed to stop him from "going vengeful."

* ''Wiki/SCPFoundation'': [[http://scp-wiki.wikidot.com/scp-1337 SCP-1337]] was initially just a harmless [[BewareOfHitchhikingGhosts Hitchhiking Ghost]] after her murder... until a Foundation researcher decided (without permission) to have her parents killed and gravesite destroyed, in the hopes that she'd "have nothing to come back to" and vanish. Instead, she became an indiscriminate killer.

** The Hammer: George Markeley was a blacksmith and family man. He became a CrusadingWidower when his family was lynched and he later killed their murderers. However, the racist townsfolk responded by turning into a mob, chaining him to a tree, driving iron spikes into his body, cutting off his hand and replacing it with his hammer. His ghost is one of the three most violent, dangerous and deadly of the 13, second only to the ghost of a serial killer and an insane asylum patient.
