If a Vigilante kills a town aligned, He becomes a "Murder" or something like that.
Alignment: Neutral(evil/advanced)
Abilities:
Fake yourself as not suspect(You have x nights when you can do this, this would be choosen in the setup)
Special Abilities:
none
Win Conditionurvive untill the end and see the town dead.
Host Options:
Can fake himself 1,2 or 3 nights as not susp.
Remove from neutrals xD
Vigilante becomes Murder at 1 or 2 town killed by him.
Becomes less points than he would if he was still Vigilante(If he wins)
This will make the Vigilante more afraid to kill without a reason or just randoming.
Note: I'm not very sure about the name of the role.
