God gave us all free choice, so we would make our own decision for Heaven or Hell. Since He wants us to go to Heaven, if we choose Heaven, He will reinforce it in us. What does this have to do with the fact that God knows everything? You are saying two opposites at the same time. You are saying that people can make their own decisions, but that God made their decisions for them.
No, I'm not saying God did anything. God doesn't exist.
I'm saying, hypothetically, if an all-knowing all-powerful God exists and created everything in the universe, then God already knows the outcome of everything. In such a universe "free will" and "our own decisions" become irrelevant. Everything happens because God made it so. We react in a certain way in certain situations because God made those situations and made us.
I'm saying that if God exists (which he doesn't), he condemns some people to hell from the moment he creates them. He creates a man, and he knows instantly that this man will be a murderer will never believe in God and will die at age 20 when he is shot and will never seek forgiveness for his crimes. He knows that the person he has just created will go to hell.
