First, really poor job regarding Esau and Jacob. Paul is not talking about nations, but about those two children specifically. The context is clear.
Second, no one is deserving of God's choosing them. Because God chooses to extend grace to one, this does not make God unfair to the other. If you want fairness, then prepare for all humanity to burn in hell. You want fatalism, try comprehending a fair God who extends no mercy or grace, just fairness.
It is God, choosing to be merciful when no mercy should be given. God chose to extend mercy to Jacob, not Esau. This is God's Sovereign right. It is the exact opposite of some morbid fatalism you have contrived in your brain. It is an incomprehensible act of mercy and grace to one who doesn't deserve any of which he receives.
It boggles my mind how the free will proponents actually see humanity as somehow good enough that God should just love their behavior and be overjoyed that humans, all by their little ole' selves just naturally want to be a slave to God's righteousness. God would, by that sick thinking, have to be an evil God if He didn't just adore those humans who brilliantly chose Him over the pantheon of other gods. All hail the human will!
Such thinking is just perverted, selfish, godlessness that takes away from the holy and sovereign God of highest heaven.
That you think God's Sovereign choice is evil fatalism says much more about your own pride and low view of God than it says about God and His revealed word in scripture. Your thoughts here are just appalling.
