Damn I knew I should have killed trashleg last night. I thought there was only one mafia left though, and decided to take out the lurker instead.
Oh and I didn't have to be a bad guy really. I just kind of chose it for the fun of the thing. I could have held off on randomly zapping lurkers I knew weren't mafia, but meh. Serial killer is just a fun role =)
Also, this is possibly the coolest role I have seen. Kudos to whoever thought it up.
