I once had a published written debate with a religious apologist who, after I had argued the standard line that the idea of a loving and merciful deity is inconsistent with the fact of natural evil, said this meant his god was not all-powerful, and therefore was not to blame because it could not stop natural evil from occuring. This is a different tack from the more robust one that says natural evil is a response to humanity's moral evil. What this latter view in effect argues is that because of (say) Hitler's wrongdoings, thousands of babies deserve to be drowned in tsunamis.
