Arl Rendon Howe is an evil aristocrat dedicated to gaining power through any means necessary. Should the player pick the Human Noble origin story, they will witness as Howe betrays and murders almost all of his best friend’s family and household. Among the casualties are the player’s young nephew and defenseless sister-in-law. When confronting him later, Howe mocks the Noble about how he made their parents suffer before he killed them. Howe is also responsible for purging Denerim's elven alienage, resulting in the deaths of numerous elves, including an entire orphanage full of innocent children. It's also hinted that he helped Loghain sell said elves into slavery. Finally, Howe is the one put in charge of conducting Cold-Blooded Torture on the nobles that disagree with his boss, Loghain, a task Howe enjoys enough that he chooses to sleep in the bedroom right next to his Torture Cellar.
Bann Vaughan is a sex offender and murderer of elven women who justifies his crimes by saying that elves aren’t real people. When he appears in the City Elf origin story, Vaughan abducts the entire female half of a wedding party, including the protagonist if female, to be raped by him and his men. By the time the protagonist fights back, one woman has already been killed and the protagonist’s cousin, Shianni, has already been raped by Vaughan and his friends. Unwilling to release his hostages, Vaughan instead tries to bribe the protagonist into letting him keep the women for the night. Such cruelty from Vaughan isn't an isolated incident either, as the DLC prequel Lelianna’s Song features an overheard conversation where Vaughan is preparing to rape/torture one of his maids over a floor stain.
Dragon Age II: Ser Otto Alrik is a high-ranking Templar who is infamous for his habit of illegally conducting the right of Tranquility on unwilling mages. Forever cut off from the spirit world, known as the Fade, Tranquil mages have undergone the spiritual equivalent of a lobotomy and are left as Empty Shells for the rest of their lives. Not content with the way things currently are, Alrik’s dream is to initiate the Tranquil Solution, a plan where every mage is forcibly made Tranquil, regardless of age or ability. When this plan was turned down by Knight-Commander Meredith for being too extreme, Alrik began taking steps to carry out his plan in secret, turning mages Tranquil such as he did with Anders’s first love, Karl. Also, in the mission Dissent, while pursuing a female apostate named Ella, Alrik heavily implies that he’ll use the Right of Tranquility to turn her into his willing Sex Slave, with the added implication that he frequently does this. This is proven in an overheard conversation between a newly made Tranquil mage and her former lover. In response to her lover trying to break through to her, the Tranquil mage emotionlessly responds, "I am Ser Alrik’s now."
