No, it isn't. People have butchered, slaughtered, killed, and died in the name of religion. Nobody in their right mind would deny that. They've also done all this in the name of politics, self-righteousness, power, lust, and just about every powerful human emotion that there is a name for. We could talk examples until we're all dead. It would simply be a waste of time. Apart from anything else, our knowledge of mental health issues is so problematic that currently we have no system of diagnosis other than a largely arbitrary one invented 30 years ago in the hopes that by now we'd have something biological to go on. We don't and unless we give up this system we never will.
Already this thread is pretty much contra the entirety of the relevant scientific fields and theories by ignoring what indoctrination is. We can look at studies which show the tendency of religious indoctrination to do good or to do bad (e.g.,
Graham, Jesse, and Jonathan Haidt. "
Beyond beliefs: Religions bind individuals into moral communities."
Personality and Social Psychology Review 14.1 (2010): 140-150.). In the end, we're still left with a subjective opinion of "bad" which requires a subjective morality to define it.
