Why even make these kids if he knows they will destroy themselves?
Didn't you forget the part about them being His children?
So he is allowed to torture people (create them just so they will destroy themselves) because they are his children?
No. There is nothing like God being allowed. He controls all things and beyond.
Free will used the wrong way is what cause destruction.
Are you dull? God is supposedly omniscient, and thus he knows everything that can happen, and will happen. How can there possibly be free will when the future has been predestined?
Once a person makes a commitment to be on God's side, God locks Him in, so to speak. That is predestination. However, if a person on God's side pulls himself free from God, he was never predestined in the first place.
Anybody who is in God will find it very difficult to jump out.
