Why are religious people so messed up?

After giving it some thought I think that is unfair.

There are many religious people and many non-religious people who are equally messed up and many religious people and many non-religious people that aren't messed up.

Serial killers may or may not be religious, but it is unlikely that religion has anything to do with them being serial killers. Hitler used religion in a way to promote his agenda, but his reasons weren't necessarily tied to religion. 

Most active pedophiles likely aren't molesting and raping children do to religious beliefs, they do it because they have a sexual urge towards children or are just pathetic people that need to use manipulation on young people to get sex. I think that in many cases religious ideas cause people to do horrible things, but I think there are equally as many cases where religious people use their power position to get away with horrible behaviors that they would do even if they weren't religious.
