I would agree that some religions (Islam) does not do good. But, Christianity, a religion that has a morality system that values life, hard work, and loving one's family is a "powerful thing that will drive the common man to act morally." By the universality law, the world would prosper on these values. Many atheists hold values which are not so great, and many are more moral escape artists than anything else. I'm not saying all are, because that certainly is not my intention as an atheist, but if universality law was applied to the moral system of a lot of atheists, the world would not thrive. Also, people like religion. Not only because of a promise of a life after death, but they enjoy singing songs, they like the holidays, they like the sense of belonging and community. Also, throughout history, most civilizations begin with a common religion. That is why I've concluded that religion, or more specifically, Christianity, can be powerful and helpful for humanity.
