Does God condemn people who never knew about him or believed differently?

Answer 1
Absolutely not.
I'm a Christian/Mormon, and I know God loves all of his children, whatever the circumstances of their birth or knowledge. What's more, God has prepared a way for every one of his children to experience life and good and evil and then choose for themselves what to believe, what to think, what to say, and what to do.
Every single person is unique, and will be judged as individuals according to the desires of their heart as well as what they believe, think, say, and do. And everyone is given the opportunity to repent, or change, in this life and the opportunity to change their beliefs after death.
In fact, that is the reason God commanded latter-day prophets to build temples - so members of The Church of Jesus Christ of Latter-day Saints can perform ordinances by proxy on behalf of those who died without knowing what we now know or having the opportunity to receive the ordinances of salvation for themselves.
It defies reason to think that God loves his children and commands us to love our neighbors as ourselves, but then limits salvation and his gift of eternal life to that small percentage of his children who were blessed with a knowledge of Jesus Christ, much less the immeasurably tiny percent who have a knowledge similar to the one we personally possess.
No, I'm certain that God's plan of salvation is all-encompassing and was designed to benefit everyone and to make available all of the knowledge and blessings and love that God has to offer to each one of his children in due time, according to their individual faith and choice and willingness to receive them.
And that is why I'm a Mormon. The more one learns about the truths of the Restored Gospel of Jesus Christ as revealed to latter-day prophets, the more one is able to marvel at the goodness and love and justice and mercy of God, who is our Eternal Father, and his Son, Jesus Christ, and the Holy Spirit - who are one God.
Answer 2
No, of course not. A just and merciful God would never send one of his spirit children to be born on earth during times of wickedness or ignorance, and then condemn that child to an everlasting damnation based on those circumstances of their birth, life, and death over which they have no control.
One of the hallmarks of true religion is that its doctrines are consistent with the one true God who is perfect in justice, mercy, and love.
