But the ranking of levels is an illusion, there is no highest level objectively, as if you don't learn anything you won't go anywhere, and this would stand for the highest level anyhow. If God wanted people to fly, he would have given them wings. You say, everything comes from God, so it was Him who gave you the choice to kill or to spare that man. Your choice is not fixed, as it wouldn't be any choice. God gives you the choice.
Fatalism says that all is destiny.
The clue of Destiny is based on the possibility of choice, so it's internally incompatible. If there was any choice in Destiny, there would be no Destiny. If to dip a body in a liquid, the body will lose on weight as much as the weight of the liquid pushed out is. There's no Destiny there at all. We change to determinism.
