The tragedy of Hermes is really the whole story there, I think. We have this guy who tries so hard and wants to do good things and the "paradise" that surrpunds him has trapped him in a position where he cannot be fallible, he cannot be weak, and he cannot need. He did NOT have wings to bear him to paradise.
When Venat said "henceforth he shall walk" she was saying "You cannot pretend any more that nobody is being left behind, that this system is perfect, that its failures are not yours to bear. You walk TOGETHER."
I think "You are so fixated on Heaven you think Earth is a misery" is exactly on; that missing the forest for the trees is EXACTLY Amaurot's flaw. That's why the only solution they could omagine for their problems was Build-A-God at the cost of countless souls. Their whole system was so absolute and inflexible that their first real solution was to bend the laws of reality so they didn't have to change.
