Why do you think that? Why do you think that after death some people have a second chance, so to speak, and can repent after death?
I think that because all must have the chance to repent or reject Jesus. And, when Jesus died on the cross, he preached the gospel to the spirits in hell, so that they could live in their spirit according to God.
See 1 Peter 3:18-19; 1 Peter 4:5-6; and Romans 14:9.
I do not know and I do not need to know but I can entertain the thought that God who is Love might be merciful and save those who never had an opportunity to know the Lord Jesus Christ.
Well you said if a person never heard of Jesus, so I'm thinking you mean are they saved in this life while they don't even know Jesus. If that is what you mean then I would have to say no because to know God and for God to know you is to obey Jesus' teachings.
John 14:23 Jesus replied, “Anyone who loves me will obey my teaching. My Father will love them, and we will come to them and make our home with them.
2 John 1:6 The love of which I am speaking consists in our living in obedience to God's commands. God's command is that you should live in obedience to what you all heard from the very beginning.
1 John 5:3 Love for God means obedience to His commands; and His commands are not irksome.
1 Corinthians 8:3 But whoever loves God is known by God;
1 John 5:20 We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life.
1 John 2:4 Whoever says, "I know him," but does not do what he commands is a liar, and the truth is not in that person.
We can see from the scriptures that knowing God is to obey Jesus' teachings.
