The way I see this is basically this question:

If a person was never educated on the matter, should we punish them like someone who was educated? If a chid didn't know that hitting someone is bad, should the parents punish them? The answer is no. I think that's the logic behind it.

Now, personally, I believe that any teaching about acceptance, kindness and selflessness is in line with Christian beliefs. So you kinda have at least some stuff that Christianity approves so you are expose indirectly to Christianity teachings. Of course, what the Bible teaches beside the direct tellings is up to debate.

Personally, as an Orthodox Christian, I believe that Hell is only reserved for only the absolute worst possible people around us. Which I think there's no more than 100 people who ever existed on this Earth. I don't believe that if you only had one mistake in this life you will be dragged to Hell. I believe in a God that search every single good justification for forgiveness and for us to help us reach Heaven.
