Could it be that people are the ones who make heaven so beautiful and hell so bad?

I wonder if heaven isn't as good as we think, or hell isn't as bad as we think? Could they not be pre-created places of infinite beauty or infinite pain? What if heaven and hell are two different, simple, ordinary worlds, the only difference being the people who will go there? What if the goodness in those who go to heaven makes heaven so beautiful, and the evil in those who go to hell makes hell so bad? As I was thinking about it before falling asleep last night, a thought like "some people (the "some people" that came to mind were r*pists) are bad enough to worsen the hell" suddenly popped into my head. I found it interesting, so I wanted to hear other people's opinions.
