Souls and God

Now I haven't read much about logic or stuff so if someone could formulate my problem with a better language I'd be thrilled.
Let's say God is omniscient.
Because of his omniscience he will only act in one way, seeing how he's because of mentioned omniscience seeing himself act in the future, now and the past.
Now let's take a soul.
God is the creator of all souls, since he is the creator of everything. Which means that he makes a conscious decision when creating a particular soul. Because of his omniscience he will see this souls future before he's even created it, he will see whether or not this soul will sin or not.
Now here comes my point:
If God is truly omniscient, then why does he knowingly create souls that inevitably will sin and revolt against God, thus being condemned to hell?
The way one can explain this is if God's either not:
Omniscient

or

All benevolent

What do you guys think?
Did I think it through this time?

RedCream you fucking idiot. Even thought something can't exist we can discuss from it. Darth Vader and Gandalf don't exist either, they are written characters like christian god. We can discuss about, how Darth Vader killed Obi-wan and so on, even though this never happened. I'm not religious either, but I like the lore behind Bible. Not the lame stuff, but mostly the demonology and ranks of angels.
