There are other things missing in Heaven too: compassion, empathy and mercy.
If all the suffering is in Hell;
and all the sufferers deserved their fate;
and everyone around you is in a state of bliss and deserves their reward;
then there is no need to possess any of those qualities because there would never be anyone around you either suffering or wronged.
Because there would never be anybody in the wrong place, there would be no need to feel what the other is feeling.
So Heaven must be a place of stern, uncompromising severity with no compassion nor any need of it. If not for the eternal bliss of union with God, that sounds like the very worst kind of dystopia going.

If I weren't an atheist, but still had a lingering desire to believe in something, this whole line of reasoning would probably take me straight down the Left Hand Path with my eyes wide open and a smile on my face.
