Dude, that’s like praying for the salvation of Satan himself.
He is an alien and a destroyer of the things of God.
Pray as you see fit and feel led to do, but I think you got this one wrong.
Mt Dawg, Satan and demons are unredeemable but sons of Adam are even Barry - O (Rom. 5:12-21)
My dear friend see the ETERNAL picture (Rev. 20:11-15)… that is out right anti Christ in what you have stated and anti biblical (Matt. 5:44, Like 6:27-28, Rom. 12:14). My dear friend you are better than that. If you know the Savior (John 1:12) and what He has done for you (Gal. 1:4, Eph. 1:7, Eph. 2:1-12, Rev. 1:5) there is no way that you can make that statement.
May you see the big picture and know TRUE forgiveness (Luke 18:13)
