- Vilgefortz of Roggeveen was an ambitious, misogynistic member of the Chapter of Sorcerers who desired unlimited power at any cost. Vilgefortz betrayed his sorcerer comrades to Nilfgaard, facilitating a bloodbath, not even because he actually switched sides, but to create a distraction for his own personal power play. He thought that Ciri's "blood" as per prophecy didn't refer to her progeny, but to her actual blood, so he performed vivisection experiments on living women, the results of which made even hardened special agents blanch, in preparation for extracting Ciri's placenta, so that he could use it for some arcane purposes. Incapable of feeling empathy for anyone and craving world domination, Vilgefortz's plans repulsed even the other villains of the piece's Crapsack World.
- Leo Bonhart was a bounty hunter originally tasked with killing or capturing a young girl named Ciri on behalf of two different patrons, but when he found her, instead of doing either, Bonhart decided to take Ciri for himself. Before that though, Bonhart enjoyed himself by slaughtering the Rats, a criminal group Ciri was staying with who robbed from the rich and gave to the poor. Murdering them and cutting their heads off, Bonhart saved Ciri's lover, Mistle, for last, forcing Ciri to watch as Mistle died slowly and painfully before he cut off her head as well. Once Ciri was in his clutches, Bonhart beat her, drugged her with fisstech, and forced her to kill people in fights to the death at the Claremont arena. Bonhart would later kill Neratin Ceka when he tried to help Ciri escape from Bonhart, Rience and Skellen at the village of Unicorn. Deciding to hunt Ciri down for Vilgefortz, Bonhart first asked if he could watch Vilgefortz's planned vivisection of Ciri as part of his payment. Bonhart eventually participated in the defense of Stygga Castle, where he once again tried to kill Ciri and succeeded in killing her ally, Cahir. Bonhart relished fighting and killing more than anything in the world, tried to rape a prisoner at one point, expressed a desire to rape Ciri either before or after impaling her on his sword and feeling her slowly die, and was so evil that a psychic found the sensation of scanning his mind akin to sticking her head into a freshly opened grave.
- The Witcher:
- Azar Javed is an Evil Sorcerer and Mad Scientist all in one and the front-man of the evil group Salamandra. Murdering his teachers for objecting to his use of forbidden magic, Azar Javed recruited many humans to Salamandra. Javed used his followers at cannon fodder to attack the Witcher home castle Kaer Morhen to steal their secrets on mutation and had children captured to serve as test subjects for the experiments. He used many humans as the subjects of the experiments and led the Salamandra on vicious anti-human crusades, leading to the deaths of many innocents. Azar Javed would also murder a man by infesting him with the eggs of exotic flies and murder a detective who got too close to his trail before confronting Geralt and trying to kill him as well.
- The Reverend, the spiritual leader of Vizima's Outskirts, seems to be a fair, if slightly rude priest at first glance, but is actually a Knight Templar psychopath. He has his own pregnant daughter thrown out of the village for refusing to follow the psycho-cult religion he does, forcing her to become a prostitute just to get by, and tricks his own people into believing that the innocent, kindly mage Abigail is responsible for the recent rise in monster attacks, forming them into a howling lynch mob. He does this merely out of petty spite and prejudice. If Geralt (rightfully) prevents the lynching, even after saving the village from the monsters, the Reverend will try to have him killed, again purely out of petty spite. He doesn't fight Geralt himself first, but manipulates dozens of innocent villagers to attack, willing to sacrifice the lives of his own village just because Geralt hasn't let him murder an innocent woman.
- The Witcher 2 Assassins Of Kings: Bernard Loredo is the thuggish Commandant of Flotsam who runs the town like his own personal fiefdom, running criminal enterprises and instituting racist policies against nonhumans. When Iorveth's men kill some of Loredo's, Loredo sends out his soldiers to incite riots against the innocent, nonhuman residents of Flotsam, leading to butchery and mass murder of nonhumans in the streets. Eventually, Loredo has the Scoia'tael members and their sympathizers rounded up on a prison barge which he plans on sinking instead of delivering to prison. If Geralt sides with Roche and kills Loredo, the Witcher will discover, despite Loredo's hatred of nonhumans, the Commandant imprisoned, beat and raped an elven woman for a year, eventually impregnating her. The woman was so traumatized by the events that immediately after giving birth she killed herself. Should Geralt choose to side with Iorveth and hijack the prison barge, Loredo responds by spitefully trying to burn down a building full of elven women. If Geralt chooses to save the women rather than kill Loredo, Loredo will succeed in turning traitor and selling out Flotsam to the kingdom of Kaedwen.
