Sleepy-
Are you seriously contending that religion has made human society more moral?
HMMM, Let's see:
The Inca and Maya offered their children as sacrifices in the name of religion. So did those who sent their children off on the Children's Crusade.
Religions all over the world have required human sacrifice. Even Abraham was willing to offer Isaac up when asked.
Thousands of people were killed in the Inquisition in the name of spiritual purity. Religious ferver inspired the inquisitors to particularly grisly heights of torture.
More thousands of people (on both sides) were killed during the Crusades.
The Bible speaks often of wiping out whole cities and civilizations in the name of religion.
Ritual prostitution was praticed in many ancient religions.
More thousands were killed in New York by terrorists who were sincere in their belief that they were perfoming the work of their god.
Proseletyzing has been responsible for the desctruction of hundreds of indigenous cultures.
Hitler felt his religion justified his organized attempt to destroy all Jews.
Humans have used religion as their excuse to slaughter each other in Bosnia, the Middle East, Africa and dozens of other places on the Earth.
Religion was the reason for the destruction of the library at Alexandria.
Thousands of people were burned or hung (or otherwise murdered) to rid the world of "witchcraft" (read anything not Christian) in the Middle Ages.
Sorry, I'm not convinced that religion has had some type of "civilising" or "moralising" effect on human-kind.
