I haven't watched the movie yet so I'm not sure if an SK would fit (or maybe some other 3rd party or 2 mafia team setup)
I see a bounty hunter like Bobba Fett being classed as a serial killer.
Unvote: Slappy
Vote: The Warrior.
The inactives are dangerous to have in the end game. You don't have a good read on them if they are scum and if they are town they don't vote or vote uninformed.
Only The Warrior can save himself now.
