Spyr, this seems like a deliberate attempt to create conflict, just like the initial idea with the ultimate ability. They nominated two candidates to pit them against each other, to create animosity and rivalry between them (while other players also get involved, voting based on their preferences or other reasons), to gather their votes, and then discard one of them, even though both could be decent. They'll eliminate one and then realize that he was actually a good guy, and tomorrow they'll switch their attention to the second one. Who benefits from this? Exactly. By throwing out false accusations during the day, they can gain time at night to pursue their own nefarious goals.
It's a good move, I must say. Especially considering the number of easily influenced players.
