And considering your "divine" deity acts exactly like an Arab patriarch: jealous, autocratic, mercurial, exacting, and violent, it's clear that in creating a god, man has always looked only within his self for explanations of attributes and motivations.
Murder is murder, matters not what the murderer believes or doesn’t believe. Again, this in a human problem, not a “god” problem. I would think both beleivers and non-believers whould be able to agree on this.
