I'm not a believer, but I think that overall religion has contributed more good to humanity than it has done evil, even if sometimes this is a close call. Our moral codes, and to some degree, our legal perspective is an outgrowth of the Judeo-Christian theology that generated the Western world. Personally I find it amusing that some people think of the Creator, if there is one, as aware of and involved in the lives of billions of human beings living on this little speck of a planet on the edge of a non-special galaxy in a universe of unimaginable size, and many of these same people think that there is a singular entity that they call Satan that consciously tries to influence people to do evil things.
