Hm...

I'm not liking the way Crazed Rabbit keeps saying "I'm not the Godfather or a mafioso."

His behavior in past games indicates that even when he is in the role of a villain, he tries to avoid telling an outright lie. He'll happily mislead by omitting the truth, but will try to end the game in such a way as to be able to say "I never lied" at the end.

It could be that he has the mafia-support role and Sigurd or Myrddraal is the Godfather. Between these two I'd pick Sigurd. His early-game maneuvering may have been dangerous - why would the Godfather put himself forward so much? - but now that he's survived to the end-game it's a great cover.

I still think Crazed Rabbit is the one to lynch, but if the game doesn't end after that, go for Sigurd. I'm almost certain he's a villain of some kind; he's more likely to be support for the mafia, but he could be the Godfather as well.

I shudder to think that Myrddraal might be the Godfather as well. We don't have that many lynches to waste.
