Certainly Satan knows very well what his future holds. He can read this passage as well as I can. He knows God has won/will win. He’s the ultimate biggest loser.
So, what doesn’t he just give up already? Why can’t he slink back to his pit and sulk by himself? He knows he can’t outwit or outweigh God. Yet, he continues to stalk and mame and torture Jesus followers and those yet to follow. Maybe he takes some twisted pleasure in knowing it’s possible for him to drag away and deceive some who might otherwise find themselves en route to heaven. Is it possible that he’s proving out the adage “misery loves company”?
