For trying to kill the mod in a game where killing the mod will probably be bad...I mean, after good things happen in three Tar games for lynching the mod, I don't thinking killing the mod would be a good thing here.
Also, I highly suggest taking a look at MS1, MS2, and Babylon 5 mafia for reference to roles that may or may not be in this game. It's good to get a feel for Tar games if you've never played one before.
