I think the quest for satan is to constantly refine his ability to impart demon heredity into the human stock, without making it too obvious in a nasty looking way, especially to ultimately create the anti Christ and his minions. This is why he is so hung up on genetics. As in the days of Noah.....
Interesting point. He does seem to focus on that a lot. Some say, he’s building an army to joust with God and angelic forces at Armageddon with higher numbers than he started out with at 1/3 of the angels who fell with him.
