I was actually thinking on a similar thought line as to this. but mine was more along the lines of God making the Leviathan to constantly consume the darkness and eventually became corrupted that way. then God realizing that it wasn't working decided to make the Archangels to help fight it off. but really it is all because of the different writers, this is the third head writer for the show, and they kind of keep just coming up with a newer bigger bad than the last (author and previous baddy.)
