mothy confirmed in Pierrot that the sin demons have nothing to do with Eve, and are just what remains of the godkin. He's not vague about the "sins"--it's made clear through the series that what the English fans originally thought was "Sins" as an abstract magical concept was just the demons, and a way of referring to the demons. IE, "Vessels of Sin" is not a vessel of "sin" as a concept, it's a vessel of a Demon of Sin.
