The prophet Amos makes some general statements of how God operates.

“Are you not like the children of the Ethiopians to me, children of Israel?” says Yahweh. “Haven’t I brought up Israel out of the land of Egypt, and the Philistines from Caphtor, and the Syrians from Kir?”
Amos 9:7

David calls on God to punish wicked nations.

“You, Yahweh God of hosts, the God of Israel,
Rouse yourself to punish the nations.
Show no mercy to the wicked traitors.”
Psa 59:9

Further, if you look at the context in Psalm 59, David included the wicked among God’s people to also be destroyed for they are plotting to murder David for no valid reason. In this psalm the wicked among God’s people are counted as among the nations (Psalm 59 introduction, and verse 5, etc.

God uses even the wicked, to wipe out evil nations

God’s very own people had sinned against Him, and turned to wickedness, deceit, adultery and blood shed. God’s own people now deserve judgement and punishment. So how does God act in these things.

“For, behold, I raise up the Chaldeans, that bitter and hasty nation, that march through the breadth of the earth, to possess dwelling places that are not theirs.”
Hab 1:6

The Lord speaks at length about the strength and wickedness of the Chaldeans / Babylonians.

“9 All of them come for violence. … 10 Yes, he scoffs at kings, and princes are a derision to him. He laughs at every stronghold, for he builds up an earthen ramp, and takes it. 11 Then he sweeps by like the wind, and goes on. He is indeed guilty, whose strength is his god.”
Hab 1:8-11

When mankind deserves to have nothing
but an animal rule over them,
how will God act?

God Himself will raise up the “beast” Revelation. God Himself will give this animal authority.

“It was given to him to make war with the saints, and to overcome them. Authority over every tribe, people, language, and nation was given to him.”
Rev 13:7.

God helps this monster deceive the entire world, because they reject the truth of God.

“And for this cause God shall send them strong delusion, that they should believe a lie:”
2Thes 2:11.

And when the prophet Zechariah speaks of this “beast,” calling him “the foolish shepherd,” or “the idol shepherd,” he specifically says that God is the one who will raise him up.

“For, behold, I will raise up a shepherd in the land, who will not visit those who are cut off, neither will seek those who are scattered, nor heal that which is broken, nor feed that which is sound; but he will eat the flesh of the fat sheep, and will tear their hoofs in pieces.”
Zech 11:16 KJV

The word “land” here is the Hebrew word eretz and can mean either a land, or the earth (as in Genesis 1), and probably should be translated “earth” here. This foolish shepherd will be killed, but not by men, but will have some sort of resurrection, by God’s allowance.
