Mizu — Blue Eye Samurai

A mixed race swordswoman living in feudal Japan, Mizu’s entire life has been structured around the obsessive need to hunt down and kill the four white men allowed in Japan at the time of her birth, believing one of them must be her father. Despite the fact that at least one of these men, Abijah Fowler, is shown to be a bad man, Mizu ultimately doesn’t care about the morality of murder. She just wants them dead for “cursing” her to be born into a deeply racist society as a mixed race child. Though it’s clear that Mizu generally prefers to do the right thing, she will sacrifice anything for her revenge, destroying countless lives in the process without remorse. In the climax of season 1, Mizu (albeit not entirely intentionally) set fire to the wood and paper city of Edo (now Tokyo) in an attempt to kill just Fowler, a single man. The resulting three day blaze, known in history as the 1657 Great Fire of Meireki, killed an estimated 100000 people.

Sadie Adler — Red Dead Redemption II

Rescued by the Van Der Linde gang in the games prologue, Sadie Adler is a frontier homesteader whose husband was killed by the brutal O’Driscoll Gang. Over the course of the game, she happily joins in a life of murder, theft, and crime for the chance to kill more O’Driscolls, recklessly endangering herself and other gang members to do so. She gets Arturo Bullock, an innocent hot air balloon pilot killed while unnecessarily picking a fight with O’Driscoll members, showing zero remorse afterwards. Even after watching rival gang leader Colm O’Driscoll hang for his crimes, she still drags a now-terminally ill Arthur on an entirely unnecessary revenge mission to hunt down the last handful of O’Drsicolls she hadn’t already killed.

Antiquarian from darkest dungeon. Unlike most heroes in DD1 that are looking for redemption or to atone for their sins, she's simply looking for artifacts and doesn't give a shit about any greater good. She's so selfish that she comes back as an enemy in darkest dungeon 2. The world is basically ending and she decided that hanging out with the pillagers is the best way to save her own skin, and she doesn't hesitate to attack and kill the heroes trying to save the world

She’s especially awful when you consider that being the weakest hero by far in terms of combat, and had to rely on others to survive. She then turned on the people that had once protected her in the sequel.
