Some of these questions are a thousand years old.
I have found my own answers, but it’s like climbing a secluded mountain to find others at the top to greet you...
Seriously, you seem to be having problems with the concept of free will.
God is omniscient and omnipotent, but he chooses not to have men - created in his image - function as mere robots or zombis. That does not detract from his omnipotence - which itself does not demand exercising power to the greatest possible degree all the time (because then it wouldn't be omnipotent, would it?)
God knows that men will sometimes abuse the free will that he has loaned to them - but the alternative, that no-one have any power to freely choose to love God and serve him - is worse.
Lewis again: "There are only two kinds of people in the end: those who say to God, 'Thy will be done,' and those to whom God says, in the end, 'Thy will be done.'"
