I see what your saying and I was wondering about that too..

I think that as long as a person is loving and caring throughout life and shows compassion towards others, is willing to sacrafice for those they love etc. They get marked as a good person because they generally are and I think they'd get kind of like a free pass into heaven. I don't think God would punish them for 'not having faith' when first of all they've never had the oportunity to learn about the Lord and accept his love and 2: they were a good person on Earth to begin with , which says more about their character.

Some people are only kind to others because they are trying to buy their way into heaven and will over God, but these other people who aren't aware of religion and are sill kind, are overall good people because they're showing compassion because they want to, to help others, not to achieve something for themselves

~sorry if thats a little confusing and dragging on, hopefully I somewhat made my thoughts clear
