Another issue is that we gain corruption from lynching/killing the wrong people. I think the Mafia's objective is to get our corruption high enough...(Since in the OP, it mentions the Mafia has "Unknown" victory conditions, rather then just "kill everyone")

If we lynch edse and he is innocent, everyone who voted him gain's corruption from it. I don't think it's a good thing to gather too much of it.(Why my vote is staying off him or Ironside, I am settling this like a real mage would.)
