I have had a discussion with a Muslim friend of mine about this. He tells me that the Qur'an makes it clear that even if one lives a good life, helping to improve the world, they would still go to Hell for eternity.
I have a problem with this.
Are all the Native Americans who never even heard the word Islam, burning in Hell? Are the North Koreans who are brainwashed from childhood to believe that Kim Il-Sung and Kim Jong-Il are basically deities destined for Hell?
