Great game! Love the phylosophy.
Spoilers ahead:
I think purgatory is the best place for her, and she will definitely make it out, since she has showed so much determination before.
I admit I was not capable of playing the "send her to hell" ending, and had to watch other gameplays. It is just so unfair. She was just 15, and basically none of her choices mattered, since they would all die anyway. But its not like she is completely innocent, since her family opinion should matter too, and you cant strip away other's people choice over their bodies like that.
Powerfull game!
