A Hitman is a mafia-aligned role which essentially acts as a scum Vigilante. It functionally works the same as a Vig by giving the mafia team either a daykill or an additional nightkill. The daykill, as with Vigilantes, could either be anonymous (PM to the moderator) or posted publicly with a ##kill PLAYER. An anonymous daykill would be more beneficial for the mafia's desire for secrecy, but a public daykill could be WIFOM'd as a fakeclaim. Meanwhile, giving the mafia a second nightkill makes the mafia twice as strong. If you give the mafia a nightkilling Hitman, make triple sure it's balanced, because otherwise the town is going to be screwed.
