Ah. Well... considering some of the things you can do in The Other World, (killing a child to end their suffering, for example) it might read that way. I'd say Necromancer and Alpha Wolf could, too, depending on your choices, and Eternal (as previously stated) isn't a bad suggestion either.
"Mommy, Can I Go Out and Kill Tonight" is about a former cop killer who became a psyche nurse to help people, but still has flashbacks and issues with authority, and can go on a killing spree depending on your actions. He can also drug a dog and gun down people for the sake of a friend... :P I can't think of any others atm, but I'd advise looking around. It's a common trope.
