As a converse to your question, is this the behavior of someone acting in good faith?
No, of course not. But I am sane, he may not be. Actually, come to think of it, he doesn't even have to be insane to explain his bizarre behavior. I have run across so many in my life that functioned well, sort of, in the workplace and social situations, but would perceive threats, see insults, take offense, where you and I wouldn't, and react differently, strangely than you or I.
You can see the same personality issues in play here, which explains Para's "WTF" happened to LF. Rossi believers, for which I was once, often explain his odd behavior away by comparing him to Tesla, and Edison. One thing they forget, is that those two actually produced products, whereas Rossi has yet to do that. He is still at the promise stage, 9 long years into his promises, and that is starting to ring hollow. Very much so.
