Dude, I can find quite a bit of immoral behavior throughout the history of religion. Crusades, inquisition, witch trials, halucaust, suicide bombings, jihads, slavery, child molestation, these are all things that either have happened or are happening by religious people. I would not call those things morality. But I'll bet I know who would, religious people.
I'm not saying all religious people are inherently bad people, there are some religious people who aren't as fanatical and who are pretty good people. But throughout history, the bad has out-weighed the good coming from religion in my opinion.
