I'll only comment on the beginning, where you derail completely. An innocent soul could not have redeemed the world, else any angel could have done it. No, I think ancient Bishop Proclus said it best, to paraphrase, no man could bear the entirety of human sin, no immortal angel could relate to human sin, only a divine lamb could accomplish in one great sacrifice this salvation.

By the way, death ain't sleep, by a long shot. But you'll find out.
