The Batman killer in Colorado reminds us all once again of the argument from evil that is the best defense against Jehovah's Witnesses at the front door, friends who "pray for you," and all others still clinging to the God Delusion. My favorite explication of the argument was put forth by John L. Mackie, the Australian philosopher. He demonstrated the utterly fallacious claim that God is both good and omnipotent, since an all powerful good deity cannot but prevent evil, leaving one to wonder why it occurs with such regularity. James Eagen Holmes disproves the existence of God by murder of innocent total strangers. Those who counter with the claim that God gave man free will and thus it is man who makes such evil choices simply ignore the obvious: God could have made certain that Holmes would choose good over evil, and thus many lives would have been saved.
