I would be pissed. I get punished for thinking that I, the second most powerful being in the universe, should get a say in what is happening. Here dad is making billions of creations and leaving them to tear each other apart. I give them something to help them survive and be more than beasts and what do I get? Some burning pit filled with rejects.
I would eventually forget the heaven or the mortal world and try to turn hell, or at least my section of it, into my own paradise. This would probably look a lot like a more ordered Vegas.
I would then start filter feeding off the damned souls god keeps throwing my way, employing the minority who might be useful while keeping the rest penned in some moderatley nasty section of my domain. Only those who would oppose me directly or who I needed to make an example of would need -real- hell. Screw the creator. I will start heaven anew RIGHT HERE.
