Hooker, our little antagonist doesn't really believe all of the Bible, he just picks what he wants, which is usually a shallow interpretation of some scripture, that he most likely has not actually studied in context, if at all. For example Christ Himself in Matthew Chapter 22 verses 35,36, and 37 instructed the disciples to arm themselves against evil.
He might possibly want to do a little reading also, about trying to continually pick fights, in Proverbs where the "Contentious Man" is continually discussed. It is difficult to discuss things with someone, when their primary weapon is sarcasm, and trivial nit picking, so I just don't.
Consider the fly in the outhouse. You know his diet, and his soul purpose is to noisily buzz around, light where he is not wanted, and generally annoy folks.
