God made everything. He has every right to do as he pleases with his own creation
I can imagine Josef Fritzl making a similar defence. There's an awful lot of word salad in this discussion but ultimately you either condemn someone for failing to save a life or you don't.
It's no defense to say that we can't understand the mind of god. We do understand that it's wrong to let a child die when it could have been prevented.
Argue all you like that it's not as simple as that but in so doing you lose the moral high ground.
Christians (and Muslims etc) regularly denounce atheists as having no moral code. Well you know what? We aren't the ones worshipping and defending the atrocities of a child killer.
You are.
