There is such a thing as an action being correct, and an action being incorrect, something being right and something being wrong.
God says He wants us to follow HIS viewpoints, not ours, and then explains what those are, and we can apply them in any culture. He wants us to love Him with our whole heart and mind and love our neighbor as ourselves.
Because God is not an "it" or some non-personal force, He is involved in our lives. He did not just create the universe and then go away. He is loving, and merciful, and wise, and only can do what is ultimately right and good in all situations.
He raises up nations and He takes them down. He allows evil to continue to be used for His purposes. If people are rejecting Him, often when things get bad enough, they finally will turn to Him and repent. And then God does help them. When He blesses them, they forget, and go back into their sin, until something finally gets their attention. God uses all these aspects to try to bring us to a real relationship with Him, where we want to serve and love Him willingly.
God can choose to allow "compulsions of a group of people" to rise if they are righteous, or the opposite, rise as they persist in evil. He chooses how to run the world. He is all-knowing and all-wise, and His ultimate aim is to get sinful people to turn from their sin and turn to Him.
So within each nation/history/geography/perspective you mention, are humans, people created in His image, the people He loves. Because He is holy and cannot lie, He is faithful to keep His promises, and works to try to bring each individual in whatever their worldview is, to Him.
If they turn to Him, and have been in a "wrong" worldview, He works to change their hearts and minds first as individuals, to transform them and make them more like Him, and then they work within their nation to get rid of the evil and advance His good. "
Why would God want to..."
Because He is good and full of grace and truth. He IS love! And we should be thankful and turn to Him and His forgiveness offered in His Son Jesus' death for us, before our own time here is through, which moment we never know.
