It's nice that religion has helped people you know, but I'm afraid what you say simply isn't the case. Just look at the theocracies of this world, look at fundamentalist Christianity, look at the historical role of the Church, look at the Vatican's political affiliations over the past 50 years, think about the nature of faith, unquestioning obedience and belief always in the absence of proof and how one might exploit that to control a nation. A nation where perhaps 50% of people choose not to believe in the Science that is in their faces all day, every day.
Also, personally, I think telling small children that if they don't follow a set of arbitrary rules (and morality does NOT stem from religion), and give unconditional love to a celestial dictator, that they'll burn in a place of unimaginable torture for eternity, is morally reprehensible.
