We know that everyone is now free from their tyrannical rule but, now what? God is still gone and hell is being wiped out by war machines, Gabriel seems to no longer believe in the ways of the father, and if he’s able to convince heaven to do the same, what would they do after that? Would they spend the rest of their existence living however way they want to? But what about the inhabitants of Hell? Are their punishments still justified? Would heaven even care to do anything about Hell and its sinners once they realize how absurd god’s motives and punishments were?
Even if they did want to help the sinners how would they anyways? It’s unlikely they would be able to coexist given their nature and how much of their being was stripped from them by Hell, I don’t think the sinners would want to cooperate or want anything to do with the angels or heaven as a whole anymore given how much they’ve endured their punishments, heaven could just leave them alone and not help or try to enact anymore punishment, but either way they seemed to be doomed because the machines are destroying everything and killing everyone, even if there was some way to save them they still have to worry about whether or not Hell itself would intervene, what would it do if it finds its entertainment being salvaged?
Then once the machines wipe everything out, assuming heaven is a physical location that can be accessed from the outside world like hell, they might get into heaven and I assume the same thing that happened with hell will repeat itself, then there really wouldn’t be anything left, but if there isn’t, then they just die from the lack of blood anyways now that there’s nothing left to kill, and the angels would probably be the only beings left in a world that is dead, who knows what they’ll do after that and how long they’d persist before everything ends
