Even better then, but I wanted to be sure people understood I wasn't giving a clinical definition they could nitpick about from what they read in their psychology class. I think this is too broadly defining mental illness. People die all the time for a cause, especially when it is perceived to be a war for the soul of their society. We have evidence he shared these beliefs. I don't think people like this are mentally unsound unless their families confirm they had problems perceiving reality, even if I disagree with their reasoning.
