Hmm... missed this. So...
1) Raynor Raiders will want Devil Dog dead so that Town will support the lynching of Mengsk. Town can kill off Raynor Raiders after Devil Dog and Mengsk is dead. Can kill and recruit, meaning number over town grows by 2 per day if lynch is correct, 3 if lynch is wrong, assuming successful recruit everynight.
2) Town will prefer that Mengsk is alive, so that their chances of winning is higher. In this sense, town will try to be as passive as possible to avoid being marked for death. Citizens are lucky because they can join the Raynor Raiders - the sure win faction.
3) Devil Dog will be hunted by Raynor Raiders eager to convince town to lynch Mengsk. Mengsk will try to keep Devil Dog alive until Raynor Raiders have whittled down in number. But try telling that to the Sheriff, Investigator and Nova.
