God and Christ are over Satan--this has nothing to do with the trouble Satan causes on the earth Christ is KING now and forevermore--to say what you are saying is exactly what Satan wants! If a kingdom has a ruler, there may be those of lower rank like Haman who do evil, but the King still has authority over him and his end was in the king's hand, just as Satan's end is in Christ's hand.
If there is a kingdom then there needs to be a king and Satan is not it.

1 Corinthians 15:24-28
Then comes the end, when he
delivers the kingdom to God the Father after destroying every rule and every authority and power.
For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death. For “God has put all things in subjection under his feet.” But when it says, “all things are put in subjection,” it is plain that he is excepted who put all things in subjection under him. When all things are subjected to him, then the Son himself will also be subjected to him who put all things in subjection under him, that God may be all in all.
John 17:1-2
When Jesus had spoken these words, he lifted up his eyes to heaven, and said, “Father, the hour has come; glorify your Son that the Son may glorify you, since
you have given him authority over all flesh, to give eternal life to all whom you have given him.
