To B214.

The reason I theorize Lilith and Lucifer "becoming" Devils is that Lilith was originally Adam's wife, but exiled herself because she didn't want to submit herself to Adam and God.

And Lucifer left, or was banished from Heaven for rebelling against God. And the of Lucifer Bloodline is the only Devil bloodline that has multiple Devil wings (12 in total, just like a High-Ranking Angel).

I do think that Devils already existed in the world, since there are myths of them even during or before the time of Adam and Eve. So I think Lucifer and Lilith somehow became Devils, rallied the other Devils to their cause, and went to war against God and his Angels.
