Well, first of all, I'm assuming that you're doing that to both groupings (since otherwise I could say "Well, one has only one person and one has a massive number of people, which is a difference." but that seems like a trivial point)
So if you apply it to both, then it's just one person considering tradeoff A, (pay torture to go speck free for eons)
And another person considering tradeoff B(personally build pyramids for eons to get to live in your own collection of pyramids for some years.)
I could say that in once case the pain is relatively dense (torture, condensed to 50 years) and the pleasure is relatively sparse,(speck free, over 3^^^3 years) and that in the other case the pain relatively sparse (slave labor, spread out over a long time) and the pleasure is relatively dense (Incomprehensible pyramidgasm.).
I'm not sure if that matters or in what ways that difference matters. I'm really not up to date on how your brain handles that specifically and would probably need to look it up further.
personally build pyramids for eons to get to live in your own collection of pyramids for some years.)
No. Building pyramids as humans. And enjoying them much, much longer as they stand there, for Felix. Enjoyed by Felix.
Maybe the amount of our pleasure with Giza pyramids already exceeded the pain invested to build them. I don't know.
Can all the pains of a slave be justified by all the pleasures of the tourist, visiting the hole in the rock, he was forced carving for 50 years?
Or can a large group of sick sadists are entitled to slowly torture someone, since their pleasure sum will be greater than the pain of the unlucky one?
I don't think so.
