@Bennia Lover

I only said you shouldn´t compare so strictly real life myths with the Light Novel, otherwise devil wouldn´t need the evil pieces to replenish their numbers. In the real life myth devils and demons are born from the souls of evil humans and in the real life myth lucifer is the first fallen angel, it doesn´t matter if he is evil or personifed evil  himself t.

And i quote B214 himself

DxD Myth =/= Real life myth

DxD Myth =/= Real life myth.
