There's a world of difference between creating someone whom you know will go to hell and creating a person for hell.
The difference is one of intent.
One has a God who loves us and creates us, knowing some will not choose him.
The other is a malicious God who creates people especially to be tormented.
One path is one of love, choice and return of love. The other is of pointlessness, of being automatons, of having God punish people who have not faulted themselves at all.
The other difference is for us.
I do not know how my story will end. But if I were to believe that God had created some for hell then there would be no hope for me;
a) hope would just be an illusion as without free will, there is no choice, nothing I can do
b) God would be a hypocrite - demanding I love everyone, yet not doing this himself
c) no love
Intent is an important thing here. Suppose you see me breaking into a house. You might think I'm a criminal. What if someone was dying and I needed to call an ambulance and the only way I could do this was by breaking into a house. The effect is the same - but the intent differentiates my actions from that of a burglar.
The same with God. We all die. Some will go to heaven, some will go to hell. The difference is whether God loves us all, and wishes that we are all saved, or that God doesn't love us all, wishes only some to be saved and creates them especially with the intent of being saved.
