when asked if he preferred to play "good guys" or "bad guys", Willem Dafoe replied, "ain't no difference. everybody thinks they're righteous"
Very true. Even Hitler thought he was doing a good thing for his world.
But back to the topic.
Jason, Freddy, Michael Meyers (any slasher movie villain) could all be followers of Khorne.
I would put Hannibal Lecter in with Slannesh.
Vader and The Emperor would fall into the Tzeench catagory for all the sorcery.
The Crypt Keeper could be a follower of Nurgle and all Zombie movie villains.
