Ooops, you tried to feel a utility. Go directly to type theory hell; do not pass go, do not collect 200 utils.

I don't think this example is evidence against trying to 'feel' a utility. You didn't account for scope insensitivity and the qualitative difference between the two things you think you're comparing.

You need to compare the feeling of the turtle thrown against the wall to the cumulative feeling when you think about EACH individual beheading, shooting, orphaned child, open grave, and every other atrocity of the genocide. Thinking about the vague concept "genocide" doesn't use the same part of your brain as thinking about the turtle incident.
