We don’t know whether Adam had a free will or not, so you cannot say God “made” him do it, God’s ordination doesn’t have to always be active; at times it can also be passive. What standard are you using for justice and love by the way? God is the standard for how we measure love and justice so to say He is not loving or just is totally nonsensical.
Furthermore, since God predetermines all that comes to pass & none of us have free-will, that means the fate of every person has long since been determined before they were even born.
Yes, scripture teaches that (Romans 9, Eph 1&2, Acts 4).
Whether you're going to heaven or hell has long since been predetermined by God, it's just a matter of moving the clock forward. It's like all of history is nothing more than a scripted play for God's enjoyment, & you're eternal salvation or damnation rests on which part in the play you were lucky enough to get. God predestined some people to not believe in him, & now he wants to send them to eternal damnation though they never had a choice in the matter? So just, so loving.
All of this is correct except for where you said, “God predestined some people to not believe in him”. Scripture teaches that God’s predestination is not symmetrical, He actively plays a role in the ordination of those He saves, but passively plays a role in those who are damned. He merely leaves them to themselves, they do not want to please God or repent (nor are they even able to do so apart from His grace) and He allows them to get what they want.
