Also, re Zeus/Hera: an interpretation I've seen a lot of, and more than half subscribe to, is: would Heracles have become a God if Hera had not driven so much misfortune and ill-wishing towards this Her husband's mortal son? Would Dionysos have been a God or a half-divine mortal if Hera had not provoked/persuaded Semele to ask to see Zeus in all His glory, resulting in Semele's death and Zeus's sewing Dionysos up in His own thigh until Dionysos could be again born?

There's a pattern here, anyway, of Zeus's mortal children achieving more, becoming more, in response to Hera's actions than they would have had She done nothing. He seeds the garden plot; She is a vicious gardener, but She gets results.
