For your way is not God’s way, and your thoughts are not God’s thoughts

For your way is not God’s way, and your thoughts are not God’s thoughts. ( see Bibles for details) 

There are levels of devils/satan who are cruel to humans but bow down before God ( all of them) at the second coming. 

God knows them all and, still with the mercy of Heaven, makes them work in favor of God’s plan through chastisement/ redemption/salvation. Love God and God’s glory.
