I have a hard time going through what @stan pointed in his post. I see Christians feel that is the right way and that is nature of god. Then I don't believe in God who is like that, or in other words I believe God is much more than that. If all those who don't believe in Jesus will be perished, or won't have eternal life only based on that fact it's completely absurd. To make a contribution to your post I often say that those who believe in something are much stronger than those that do not have beliefs and therefore they are easier to manipulate. From beliefs comes strength, but all that we see and know should be questioned, our beliefs especially since also beliefs of people make them susceptible for manipulation.
Many Christians have a very rigid view of salvation (getting saved, going to heaven).
I am going to write a blog about this to go into more detail, but basically, while I believe Jesus is the one who gets us into heaven, he will give us every opportunity and have each individual taught in a way they can understand. Death is not the end of our ability to choose and learn.
I don't believe "sinners" will be punished forever because they didn't bother to go to church, or because they broke a few commandments. I believe they will have a clear view of the consequences of their sins (murderers will get a clear sense of the anguish they have caused, for instance). Once they choose to turn away from their sins and fill their hearts with love, they too will be redeemed (get to heaven).
God wants his children to be happy, he wants us with him.
