What would it matter? We'd be predestined to either heaven or hell anyway.
there are misconceptions about predestination. the bible says all men are under sin and therefor condemned. there is none who seeks after God no not one. all have sinned and fallen short of the glory of God. the natural man loves their sin and hates God,
so we know without God intervening every single human being deserves Gods judgement or condemnation. so God is not under any obligation to save anyone.
but God being rich in mercy has decided to save some not all. if we look at God from a historical perspective He has always chosen the few over the many, Noah, Abraham and his descendants, David and his lineage which is fulfilled in Christ. Jesus said many are called but few are chosen and many are are the broad road that leads to destruction and few are on the narrow road that leads to life.
So God decided to predestine, elect, choose some not all. Paul knows this doesn't sit right with our fallen human nature and we will question Gods justice in Romans 9.
What then shall we say? Is God unjust? Not at all! 15 For he says to Moses,
“I will have mercy on whom I have mercy,
and I will have compassion on whom I have compassion.”
16 It does not, therefore, depend on human desire or effort, but on God’s mercy. 17 For Scripture says to Pharaoh: “I raised you up for this very purpose, that I might display my power in you and that my name might be proclaimed in all the earth.” 18 Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
19 One of you will say to me: “Then why does God still blame us? For who is able to resist his will?” 20 But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’” 21 Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?
22 What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? 23 What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory—
