Religion: Evil

Is religion good or evil? Humanity has scene many horrible things happen that have been caused by religion. But humanity has also seen great good caused by religion. The question is: Is it more evil than good or more good than evil. The answer is neither of these. Religion is a medium that can be used for good or for bad. For example when humans have used religion for evil, the crusades. There was nothing pleasant or nice at all about the crusades. People in power just used it as an excuse to invade middle eastern countries for their resources. They told people in europe that is they fought for them in the crusades they would immediately get into heaven. No questions asked. Clearly the power religion had over everyone in that time frame was completely wrongly used by evil men in power.
