An afterlife would be terrifying for me

[Mister Agenda]

What if you're granted the happy kind of dementia or anterograde amnesia?

I refer to that as the 'heavenly lobotomy'. In heaven you won't give a shit about your loved ones roasting in hell because that would make you unhappy and you can't be unhappy in heaven. I've also heard it put that in heaven you will realize how richly deserved the roasting of your loved ones is and you won't be able to be sad about people getting just what they deserve.
