I'd have been disappointed if you'd resisted. It's an incredibly difficult question only for those who insist on the existence of a deity with certain characteristics that imply this must be the best of all possible worlds. Give up that idea and the question becomes trivially easy: evil and suffering are direct consequences of undirected natural forces. And it seems worth pointing out that evil exists only because there are sentient beings around capable of suffering.
What a unique thought. Are you claiming that lightning strikes, tornadoes, hurricanes, earthquakes, and other forces of nature are not directed by a god intent on punishing humanity for its multiplicity of sins?
