Here is another thought.
If people cared whether others died in eternal damnation, would they stop talking on forums, and do as Christ and the Apostles, to suffer the persecutions they did, leave all behind, until their own lives were taken off of them ?
If they did, they learn to trust in God, and also they learn to not ask what is not scriptural.
Scriptural is how Israel was concluded in unbelief ( blindness from believing) to give belief to the Gentiles.
Romans 11:11 I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy.
Romans 11:19 Thou wilt say then, The branches were broken off, that I might be grafted in.
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
21 For if God spared not the natural branches, take heed lest he also spare not thee.
A better thought. Omniscient God knew Israel would fail even before He created, so He has a plan to overcome their failure:
26
And so all Israel will be saved, as it is written: "The Deliverer will come out of Zion, And He will turn away ungodliness from Jacob;
27 For this is My covenant with them, When I take away their sins."
28 Concerning the gospel they are enemies for your sake, but concerning the election they are beloved for the sake of the fathers.
29 For the gifts and the calling of God are irrevocable.
30 For as you were once disobedient to God, yet have now obtained mercy through their disobedience,
31 even so these also have now been disobedient, that through the mercy shown you they also may obtain mercy.
32
For God has committed them all to disobedience, that He might have mercy on all.
33 Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out! (Rom. 11:26-33 NKJ)
Same with the church, God didn't trust it to deliver the gospel to everyone although He certainly commanded them to do so.
God knows who loves Him, and that is why He commanded all things will work together for their good, so not one of them will be lost to Satan:
28
And we know that all things work together for good to those who love God, to those who are the called according to His purpose.
29 For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.
30 Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
31 What then shall we say to these things? If God is for us, who can be against us?
32 He who did not spare His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?
33 Who shall bring a charge against God's elect? It is God who justifies.
34 Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us.
35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?
36 As it is written: "For Your sake we are killed all day long; We are accounted as sheep for the slaughter."
37
Yet in all these things we are more than conquerors through Him who loved us.
38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come,
39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord. (Rom. 8:28-39 NKJ)
