Hoo, boy. That is an ornery bull to tackle right there. It certainly is a pleasing thought to imagine that segregation in the afterlife is as simple as good people go to heaven and bad people go to hell. I know that the Jesus Fan Club will likely tell you that entrance to heaven is not achieved though works, but through unwavering faith. Meaning that being a good or a bad person in life is not nearly as important as just believing in what the Bible says. Because, to the Christian God, we are all little shit stains who will never be good enough for him because we are all just born evil. But due to some convoluted loop-hole, if you believe that Jesus was real and you are super grateful about it, then you get to go to heaven.
Basically, according to Christianity, the racist sexist bigot who believes in Jesus Christ will go to heaven while a non-Christian who is a super nice guy and devoted his life to helping others will burn in hell. That being said, you can go ahead and create your own religion where the result on a good or bad meter determines your afterlife if it'll make you feel any better.
Personally I think that people are judged based on their actions and not on their beliefs. So the "racist sexist bigots" would actually be going to hell because even though they believed in God, they were total douche bags in their life time. On the other hand, the "super nice guys" would go to heaven because even though they didn't believe in God, they did a ton of good deeds. That's what I believe.
I'm not about to start a cult based on what I believe. Other people can do that stuff, but I'm too lazy and the entire thing is pretty useless and self-defeating. I'll just believe what I believe and let other people worry about what other people think. If you don't like it, then I'm sorry for sharing it, but I'm entitled to my opinion.
