I don't belive in God, Heaven or Hell, but the impression I get from Christianity is that he was a sinner from the moment he was born and the only way to redeem himself would be to find Jesus. He didn't, so he would go to hell.
It is absolutely correct that God has no mercy for the unfortunate. He has no mercy for anyone unless they directly request it (at which point he has infinite mercy). This is the main problem I have with the whole "God is benevolent and the source of all morality" idea.
