"I'm sorry, son. Of course I have the power to stop all these bad things from happening to you (I'm God, duh), but you see I have this bet going with the serpent about how you'll react to having terrible things happen to you, so no."

I'd like to believe it's a generally accepted truth that if you have the knowledge that something really, really bad's happening (by way of Job praying, the topic of this entire thread), the power to do something about it, and have been doing things about it before, and yet refuse because of a wager, YTA.

In such a situation, whether it's God or the world doing the torture is kinda splitting hairs.
