Yes, there have been religious wars and things like that. But the main cause??? Really, you do know that people will do bad things, whether they are religious or not. Blaming religion for bad things happening is like blaming blaming a congressman for all the failures of the government. There are many causes, and blaming everything on one thing is naive. And anyways, many religions are based on love and self control. They become corrupted by the people, not the idea. Just look up the red cross, or many modern missionaries. They aren't the problem. Just bad people doing bad things, whether they are religious or not.
