How do you justify God and hell?

How do you justify worshipping and praising a being that sends his creations who didn't believe in Him to hell to burn and be tortured for all of eternity? Most humans aren't even evil enough to do that, it seems like God wouldn't either. If we go to hell, we're suffering for all of eternity for living a crappy 80-100 years of life, where it's difficult to be presented with a reasonable representation of Christ anymore. It seems like, if we choose to leave at the Golden Gates, then we should go to hell, but not for our life on Earth. Please understand that I am not trying to insult Christianity, I am a Christian myself. I am simply, unfortunately, puzzled by this question, and cannot move further as a Christian without a good answer. Please help.
