YMMV / Masters of Horror S1E2 "H.P. Lovecraft's Dreams in the Witch-House"

• Complete Monster: Keziah Mason habitually sacrifices babies for her magic rituals. She uses her abilities to force various men to kill them for her, destroying countless more lives in the process. She also uses a Shapeshifting Seducer trick to have sex with the protagonist by impersonating his neighbor, apparently to further mess with his mind for kicks. It's later discovered that there were at least 80 baby corpses hidden in the walls of the house going back all the way to the 1600s, so she has been willingly doing this for centuries and for seemingly no other reason than For the Evulz.
