Tragically unbeyachted.
In fact, many people would not do that without the religious motivation, or, at least, not nearly as easily.
Religion is a simple amplification of their "craziness" or so.
Uh, no. I don't think so. It's like a kid going on a school shooting and then everyone blaming it on the fact he played Hitman the night before he carried it out. Any "crazy" act ("crazy" here meaning "extremely abnormal") is more than likely to be due to a number of reasons (or at the very least, a single condition with mulpiple causes), not just because of a person's religious beliefs.
You might dislike religion, but that in no was justifies you using it as a scapegoat for everything a person who happens to be religious does. That's as bad as Bill O'Reilly saying that atheists are evil because Hitler and Stalin were.
