Does religion corrupt morality?

God is dead, may Hitchins rest in peace.

Religion provides cover for immorality which can't be rationally defended. It also teaches that same immorality, inevitably turning some people immoral who might otherwise not have been. Both ways round is bad.

On the other hand, the number of people who are only good because of religion, or significantly more moral, is I expect much less. In fact in almost every deconversion story I've heard about, the person is just as good if not better afterwards.
