The Devil is mythical as is the biblical Gods. No one knows, and there has been no divine contact to even acknowledge this much less affirm it.
According to the OLD Bible, Hell was created by God, when the old apple was eaten by the children. So, no one was there except Lucifer and a third of the Angels. And no one knows whether that was 3 angels or 3 million. It is not like the angels can procreate or more are created so it is odd that we weren't given a real number, instead of a fraction.
There wouldn't be any humans in Hell for several centuries at best, so does it make sense that Lucifer would be punishing the fallen angels?
A case could be made that the Devil is God, and God created Evil.
According to the story, Lucifer and Hell would exist for eternity. Well so far eternity is over 13 billion years, but humans have only been on Earth for under 20,000 years. Genesis is of no help because it is vague and ambiguous having no clear views of real science. That is why the Catholic Church didn't like Copernicus when he told them that it was the Earth that went around the Sun. This should have been a detail in Genesis.
The reason that it wasn't is because the real authors of the bible were mere humans, and they didn't know at that time. Neither bible was written contemporaneous with its events.
So, the devil was created as the reason to follow God, not for love but out of fear of going to Hell. And why does an Angel need wings?
