The problem of theodicy is insurmountable. Falling back on ideas of free will and what not is just futile mental flips where you land right back where you started. As soon as the man on TV claims that it was God that miraculously saved him from the hurricane it has to be inferred that the same God also deliberately killed thousands of others.
Believe it or not, I have the same problem as you do. But what does that have to do with whether or not there is a creator, and then whether or not the Bible's God is that creator?
Here is the real problem. In a secular humanist world there is no way to account for the inherent value of human life. None. Yet an argument for theodicy must first presume that human life has inherent value.
Either life has intrinsic value or it does not. If you claim it does, then account for it.
In this worldview intelligent life is no more significant than bacteria. Any 'significance' is delusion. So, if there is no objective morality, then there is no ground by which to hypothesize that an Omni3 God would be unjust for decreeing mankind's destruction.
Either you really believe your naturalistic explanations for our existence or you don't. Funny that you are crying out for justice without any grounds for justice to stand on. It's arbitrary and meaningless. If mankind is really the result of unguided, unintelligent processes, then so are our thoughts, emotions, etc. And so, trying to say a god would be unjust for wiping out humanity is self-delusion. And so this position that criticizes religion for being delusional (which it can be) is advocating that we go through life......., delusional. It's just a different kind of delusion. One that is untenable, internally inconsistent and self-defeating.
They are shouting from the roof tops that this is the truth, while at the same time saying there is no truth. How does one lament evil, when their world view denies the very concept. (If it is honest that is)
Regarding Russell. All kinds of problems with his postmodern views. Under this Hitler's atrocities are no more significant than you spraying anti-bacterial cleaner on your toilet seat and killing millions of germs in the process.
To me, this is an annihilating conclusion to the believers position. These are obvious inadequacies in the face of an omnipotent creator that would care at all about his creation. And I don't expect anybody who really believes to face up to this. For instance, the Jews are still around and extremely faithful to the God of Abraham, and if such a God lets 6 million of his people get systematically murdered on an industrial scale and they still believe in his omnipotence, its safe to say nothing will change their mind that an all loving God is looking out for them. I think the same can be said for most believers.
How do we know that the holocaust was as bad as it could have been? God also allowed people to do the right thing, which of course brought those atrocities to justice.
These are obvious, but why should God stop there? It is interesting that everyone wants God to intervene in these egregious episodes. But what if God started with you?
