God does sets and removes the kings of the earth only when He intervenes to push with his will regarding the earth. Satan is the ruler of this earth and he sets the kings and removes them otherwise God will be responsible for all the evil they bring forth. This is Satan's purpose and has always been to bring defamation to Jehovah's name.

"that you will take up this taunt against the king of Babylon, and say, “How the oppressor has ceased, And how the onslaught has ceased! “The Lord has broken the staff of the wicked, The scepter of rulers, Which used to strike the peoples in fury with unceasing strokes, Which subdued the nations in anger with unrestrained persecution. “The whole earth is at rest and is quiet; They break forth into shouts of joy. “Even the juniper trees rejoice over you, and the cedars of Lebanon, saying, ‘Since you have been laid low, no tree cutter comes up against us.’ “Sheol below is excited about you, to meet you when you come; It stirs the spirits of the dead for you, all the leaders of the earth; It raises all the kings of the nations from their thrones. “They will all respond and say to you, ‘Even you have become weak as we, You have become like us. ‘Your pride and the music of your harps Have been brought down to Sheol; Maggots are spread out as your bed beneath you And worms are your covering.’ “How you have fallen from heaven, You star of the morning, son of the dawn! You have been cut down to the earth, You who defeated the nations! “But you said in your heart, ‘I will ascend to heaven; I will raise my throne above the stars of God, And I will sit on the mount of assembly In the recesses of the north. “Those who see you will stare at you, They will closely examine you, saying, ‘Is this the man who made the earth tremble, Who shook kingdoms, Who made the world like a wilderness And overthrew its cities, Who did not allow his prisoners to go home?’ “All the kings of the nations lie in glory, Each in his own tomb. “But you have been hurled out of your tomb Like a rejected branch, Clothed with those killed who have been pierced with a sword, Who go down to the stones of the pit Like a trampled corpse. “You will not be united with them in burial, Because you have ruined your country, You have killed your people. May the descendants of evildoers never be mentioned."
Isaiah 14:4-13, 16-20
