To prove religion is the cause of the evil, you must give examples of how a non-religious society would be, or has been, better.
The fact is that there has never been a non-religious society. The one's that come close only replaced one form of mysticism with another. Instead of church rule it became police state. i.e. Communism, Nazism, Fascism, etc...
The best example of a mostly secular society would be early American history, were innovation after the industrial revolution brought this nation from a horse buggy to an automobile, the electric light bulb, and Bell's phone company.
Now on the other end of the scale a strongly religious society say Arabs, (muslims) Chinese (communist state police) and African nations are far behind the "industrialized western societies".
Proof that religions are evil is found in their own Books! I suggest you read them; The Bible:
Genesis, the first book of the Bible, has Abraham preparing to sacrifice his son to God. "Take your son, your only son – yes, Isaac, whom you love so much – and go to the land of Moriah. Sacrifice him there as a burnt offering on one of the mountains, which I will point out to you." (Genesis 22:1-18) Abraham takes his own son up on a mountain and builds an altar upon which to burn him. He even lies to his son and has him help build the altar. Then Abraham ties his son to the altar and puts a knife to his throat. He then hears God tell him this was just a test of his faith. However, God still wanted to smell some burnt flesh so he tells Abraham to burn a ram.
Even though he didn't kill his son, it is still an incredibly cruel and evil thing to do. If Abraham did that today he would be in jail serving a long sentence as someone's prison-bitch. It amazes me how Christians see this story as a sign of God's love. There is no love here, just pure unadulterated evil.
