I'm not sure how much credence we should put into AAF's list. First off, we don't even know if it's a true RC. Then, of the people there, we already have ideas for who's evil/innocent, and if we just go via elimination, well... we would lose before we got lucky. Personally I think we should continue the game using our own heads more then any naughty/nice list.
Assuming his RC is true, Kashta, Bally, or Rich is definitely evil. The biggest issue is that they are all good players. Bally screwed up a bit, with the nightfall incident and her confusion there. Personally I don't think that is enough to be evil. Kashta overdefended her votes. Rich hasn't done anything scummy yet (IMO). So, who do we want to say is evil? I think Kashta, of these people, is the best choice. I've never been able to read her, period, similar to Rich. So, well, she's the one, of this list, who is the most scummy. But I'm not yet sure I believe AAF's RC.
