This is what God says:
"12Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time."
Fair enough to say he knows exactly whats going on and can do nothing about it, therefore he is taking every single person he can down with him.....that is pride and selfishness one o one.
I suggest and will commit to anyone who desires or wants to discuss this whole matter, as the entire topic alone of God's prophecy given to John about Revelation 12 and Satans work tie into other accounts given within Revelation (including 20:8), David and Matthew which paint a vivid description of what exactly is going on at this time between different participants ie Man of sin, Satan, the wicked, saints and Jews/Jerusalem at the time Satan is cast out which he is then shortly sealed afterwords during the man of sin's reign and eventual fall to Christ's return where Satan's sealing for a thousand years takes place by an angel.
