It sounds like you won't be crushed to the core if Rossi doesn't have the goods. Me neither.
(So much for being in a cult!)
Yet, if he doesn't have the goods, I for one will be disappointed in Rossi as a human being, because he would have known better, unlike (say) psychopaths who arguably are hardwired to not give a damn about moral repugnancy of deception.
Your argument assumes facts not in evidence. You essentially say that he is not a psychopath but present no real evidence for that. He lies, he cheats, he steals, and he commits fraud, all without any apparent remorse and over quite a number of years -- I don't know if he is a psychopath but to me those are not the characteristics of an honorable gentlemen concerned with the well being of others.
