The corruption of the good by the belief in their own infallible goodnes is the most bloody dangerous pitfall in the human spectrum. Once you have conquered all your sins, pride is the one which will conquer you. A man starts off deciding he is a good man because he makes good decisions. Next thing, he's convinced that whatever decision he makes must be good because he's a good man. Most of the wars in the world are caused by people who think they have god on their side. Always stick with people who know they are flawed and ridiculous.
