If humans don't like feeding the Utility Monster, does that mean that they don't have the same terminal values as HapMax, or that they just have difficulty understanding just how happy the Utility Monster is?

(There are obvious anti-zombie reasons why "how happy the Utility Monster is" is probably ill-formed, but.)

It's also worth noting that lots of humans have thought that committing large-scale atrocities is okay if it leads to overall better results down the road, and who made in many cases tremendous personal sacrifices to Feed the Utility Monster. Nowadays and hereaplace we tend to call these people "inhuman," but of course they were just as human as you or I.
