I don't agree with MM's deal. We have far too many night killers and its best if we get rid of any as soon as possible.
Who knows, tonight could possibly produce 5-6 deaths, which would limit tommorow to only 5 players. Will we bargain with MM then? Nah I don't think so, knowing we won't have many suspects up our sleeve.
Remember, in the end it's in MM's interests to stay alive and win the game and if it means turning his back on us, he'd do just that.
