But anyway, the question you proposed is impossible to answer without making generalizations off of the thousands of people I have met out of the billions of people on Earth. But from what I can see now, it seems like much of the "good" that comes out of organized religion can be attained through individual spiritual practices (i.e. praying, meditating) and much of the "bad" comes from the "organized" part of it that involves establishing hierarchy, giving people power over other's thoughts and moral attitudes, etc. I might say, then, that it does more bad than good but a lot of religious organizations are involved in charitable causes. So, it's not always bad when people come together under a religious ideology. It just often is. I think group think is dangerous in many contexts other than religion, though.
