If the Presidents of Russia and USA have free will, they can push a button and kill 8 billions of people using all the available nuclear weapons they control. Will God prevent that? If so, do they really have free will? Why to give your creatures free will if you prevent your creatures from using it since you are Almighty and you can fix everything they do?
Since nobody is convinced to be in the wrong, 8 billions of people are mislead to death because of Satan's free will to lie to them. Why does God not prevent Satan from using his free will to bring 8 billions of people to death as He does from using nuclear weapons to kill the same amount of people?
If everything involves God's will, why does God's will let His creatures use free will (He gave them) in the second case and not in the first one?
