It is your organized religions that have made it clear through their most sacred scriptures that cruelty and killing is an acceptable response to human frailty and human differences. This goes against every human instinct, but organized religion has reorganized human thoughts. Some humans have even been turned against their own instinct for survival. And so people go around maiming and killing each other, because they've been told quite directly that this is what God does to them--and what God wants them to do to each other.
