The Devastating Effect of the Cane on Adam and Eve

Luther suspects that because Cain is the firstborn, his pride grew. He had such a big head because he thought that he was God's chosen one. And I suspect that when he turns out to be instead of the Messiah, a murderer, that also was an even worse blow to his parents Because they had this false hope that they built up around him. It's fascinating to see how various commentators have taken Genesis for and used it as sort of a bigger narrative by which you can understand the whole rest of history.
