Did John the Baptist "repent" of his sins while in the womb? Of course not. Was the "lack" of free will as to what John would become unfair? I don't think so.
As Job discovered God does things for His purpose no matter how unfair it may seem to us.
BTW-God never told Job WHY He allowed the afflictions.
I am unsure how your reply is supposed to be responsive to my question. Maybe I should back up a step, and ask this:
Do you believe that man has a truly free will?
By "truly free will", I mean the ability to distinguish between, and to choose, either good or evil. Are our choices free, or is it illusion, and all our "choices" predetermined?
