You misunderstand free will. You still have too many verses to contend with that can't be explained off in some way.
Ephesians 2
2 And you were dead in the trespasses and sins 2 in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— 3 among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. 4 But God, being rich in mercy, because of the great love with which he loved us, 5 even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved— 6 and raised us up with him and seated us with him in the heavenly places in Christ Jesus, 7 so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. 8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast. 10 For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
I could go on, but just these passages alone make free will as defined by some an impossibility when pitted against scripture and the biblical definition of man's free will. This does not mean God forces us to sin, but he had to have known mankind would fall before he created us because we know the gospel is eternal and was before creation. This makes it predestined no matter how you try and look at it. The only way it wouldn't be predestiny is if God had no idea of the outcome of his own creation which makes God capable of error, which carried out to it's logical conclusion leads to a world of problems with the Christian faith. This is so that God's glory would be magnified through his perfect justice, his perfect wrath, his perfect grace, his perfect mercy, his perfect love, his perfect sacrifice, and his perfect patience. It all boils down to God's glory, not what we as created humans feel like we deserve.
If all have fallen short and none are righteous, and none of us deserve his mercy, then why such an issue with him choosing some to save to show his grace to that they may glorify him for it? The free will thing always boils down to this and that is that people somehow think they deserve his mercy and his grace and this is not true in the least. We are his creation and he is our creator. He will do with us as he pleases and who are we to argue back?
