Basically what I was implying was that good and bad are relative terms. One thing is only good in comparison to another. A perfect world could be better in comparison to our reality, but there would always be better things than others inside that perfect world. Same thing with Hell.
Also you can't really disassociate a concept such like good/bad from it's origin, the human intellect. If both worlds were to be occupied by people like us, unless they had no free will, people would always be making choices based on who they were - human. I understand that sort of defeats the purpose of your question in the first place, but I'm just saying it's kind of a futile exercise, even though I already answered saying I "wouldn't risk it".
Good and bad like any dichotomy only make sense in opposition to each other, and it's always a spectrum.
