Mafia 100. Sylvan: Tree of Life.

"He said this and that, only a Mafia member could say/know that. Let's execute him!"
Isn't that a valid option in this case? From a psychological perspective.

It's no different from saying, "Well, I'm just considering the possibilities, and based on my calculations, the only Mafia roles left are on him, so let's execute him."
Anyway, I'll send you a private message now, sorry for being so blunt. I don't want to encourage this argument.
