Wow, don't go out on a limb or anything. Indeed, one can believe in God and be murderous, at least objectively speaking, and maybe even subjectively if one is willing to risk the wrath of whatever higher power to whom one subscribes.
Though you do not find any stories of Jesus or any of the Apostles going on killing sprees or ethnic cleansing or Conquering.
The point is that non-religious folks have done far more harm to innocents. Look at China today.
Though he himself once said something like "If I had to chose a religion; the sun, giver of life would be my God." Show you where he was at....Agnostic or Atheist, maybe Deist.
