I think raises another issue. If we observe a world, with basic moral standards that we humans recognize as good and pragmatic, where many events take place that we ourselves would not impose or do to others (like cancer), and there is a claim that a benevolent God has created this world, then we must either trust the claim but not our own mind and moral sense, or trust our mind and moral sense and reject the claim. There's no room to both trust the self and the claim because there is a serious inconsistency with the claim and what we observe of the world.
Yes, I've made this argument too: that our moral intuitions are either faulty (and God would know that, too; in which case why give us faulty moral intuitions?), or our moral intuitions are not faulty (in which case the theodicy has a problem).
