Complete Monster: John Milton (aka Satan) runs an Occult Law Firm staffed by his demons and humans he corrupted. He exploits the legal system to get as many violent criminals off the hook and spread corruption everywhere in the world, hoping that the Earth will become such a perversion that it will hurt Heaven and spite God. Having to work around the free will of humans, he subtly manipulates them to give in to evil instead. He seduces multiple women over the years so he can find offspring good enough to mate with each other and further produce The Antichrist. He drives Kevin's wife Mary Ann to madness and suicide, and rapes her for half a day, leaving her with scratch and bite marks all over her body. He later taunts his son Kevin with this crime in an especially vile Post-Rape Taunt. He brutally kills anyone within his company who tries to expose his corruption. When Kevin destroys his plan by killing himself, he kills his daughter to vent his anger by turning her into a withered husk.
Milton: Well... On a scale of one to ten, ten being the most depraved act of sexual theater known to man, one being your average Friday night run-through at the Lomax household, I'd say, not to be immodest, Mary Ann and I got it on at about....(cue the creepy yet funny face) seven.
