Nobody would listen to a word a mafia stump said. It's strictly a town role, albeit an non-powerful one.
Stump is a fun role in certain games. For example, in a WWE themed game, it was the Undertaker character, who still helped town after he died. In a Harry Potter one, it was Moaning Myrtle, though that player didn't help us at all, haha.
Anyways, I digress. I'm ok with lynching Sky if that's what the majority wants. As Wang said, it would also help to clear up some feelings about you, seeing as you've been on her for awhile. I really think that's our best bet.
