Religion is pretty hard to believe if it wasn’t the one you were raised into. And it’s often times pretty hard to get out of the one you were raised into.

But outside of religion, a pretty common fictional view is that heaven is the extreme end of order, and hell is the extreme end of chaos. Neither one can harbor any middle ground, and thus they would both suck to be stuck in.

Inside religion, whatever your religion’s version of heaven is, usually depends on what “your people(local and as a whole)” would want it to be. It changes over time and distance to better fit. But never bring up that it has changed, as it has always been this one and true correct way of depicting it, to question that is some kind of sin… and hell of course is similarly fluid despite having always been “this” way.

In truth, they have both been depicted every which way imaginable.
