What Hitchens expresses in his (admittedly non-responsive) answer is essentially the problem of evil. Why would a loving and all-powerful god permit the evils that befell, say, Elisabeth Fritzl? It is (or should be) a difficult question for theists. But understand the limitations of the problem of evil.
The problem of evil is not a logical disproof of god. It could be that god is all-powerful, but malevolent. It could also be true that god is loving, but not all-powerful. Indeed it may even be the case that god is both loving and all-powerful and his reasons for permitting evil are beyond our understanding. So the problem of evil is not an argument for atheism.
This is precisely why I like Hitchens. Unlike Dawkins and Harris, Hitchens doesn’t make a case against god’s existence. He doesn’t give a damn. As Dr. Kleiner says, “The least interesting fact about god is that he exists.” The question for Hitchens isn’t whether god exists (though of course Hitchens doesn’t believe god does), but whether god is worthy of worship. In the spirit of Job, Hitchens is demanding that god account for the evil in the world. And it is not of enough for god to bark, “Where were you when I laid the foundations of the earth?” That makes god sound like the “celestial dictator” Hitchens accuses him of being.
And in these videos, where he debates the Ten Commandments with Evangelical radio personality Todd Friel, Hitchens again voices a moral (not scientific) opposition to the God of the Bible. He argues that even were Christianity true, the atonement was a wicked abrogation of our free will and personal responsibility and that an eternity in Heaven would—for him—be Hell.
