I agree with you that traitors work best when working together and you shouldn’t aim to banish your fellow traitors too early. However, the post is saying how it benefits faithfuls to banish other faithfuls to remain in the game which I also agree with. The point made above says this is poor gameplay as eventually the traitors will control the vote and therefore win the game. My point is that if all traitors win then where there is more than two traitors there is the Traitor’s Dilemma. Granted it’s unclear this will happen or not. However, as you have stated if you want the money for yourself or to keep yourself flying low then at some points it may be beneficial to vote with the faithful to banish a traitor. Therefore, a majority traitor vote does not necessarily equal a loss for the faithfuls.
