OK, so we've pretty much ganged up on the ludicrous notion that rape is sometimes a good thing. If I can direct us back to the OP...
A man, of his own free will, decides he's going to rape a woman. The moment before he puts that choice into action, God could stop him. If He did:
- He would not be abridging the man's free will. The man was free to make that heinous decision.
- He would be protecting the free will of the victim since, by definition, no one "chooses" to be raped.
- He would be preventing human suffering.
If He did not:
- He would be standing by and watching a horrible atrocity being commited while being fully capable of stopping it.
Since God clearly does not stop rapes, and clearly He could do so without abridging free will, what can we say about God? I think it's clear that the kindest thing we can say about Him is that He's not a very nice person...
