Mafia 94. Shadow War

I think the questioning was structured like this:
1. Are you Mafia? No.
2. Does the description mention a combat role (witch, warrior, rider, assassin)? No.
3. Can you kill? Yes.

Manic doesn't fit (all answers would be true), neither does witch or rider (2 false answers). And obviously, it's not one of the green roles.

A peaceful Vishmaster, who is neither a witch nor a rider, should have answered no/yes/no = 100% peaceful.

Judging by the answers, Vishmaster is either Mafia or a drug addict confusing the town. In both cases, executing him will do more good than harm.
