If God did not choose them for salvation, they are predestined for hell. Pretty simple.
“My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: and he is the propitiation for our sins: and not for our's only, but also for the sins of the whole world.”
1 John 2:1-2 KJV
Jesus death was to take all the worlds sin upon himself and Gods Will is that all people are saved believing the truth
“For this is good and acceptable in the sight of God our Saviour; who will have all men to be saved, and to come unto the knowledge of the truth.”
1 Timothy 2:3-4 KJV
God wants all people to be saved he died for all peoples sins he sent the gospel to all people and said believe and be saved
Who is the gospel able to save who was it sent to ?
“And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved;
but he that believeth not shall be damned.”
Mark 16:15-16 KJV
That covers everyone and tells us how we can be saved and also warns how we become damned
Again Gods Will is not for anyone to perish but for all to repent and be saved
“The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.”
2 Peter 3:9 KJV
People have confused this doctrine to a very destructive place
