I prefer dust specks because I insist on counting people one at a time. I think it's obvious that any single person presented with the opportunity to save someone else from fifty years of torture by experiencing a dust speck in the eye ought to do so.

This is defection, a suboptimal strategy. Each person in isolation prefers to defect in Prisoner's dilemma.

Any of those 3^^^3 people who would not voluntarily do so, I don't have enough sympathy for such individuals to step in on their behalf and spare them the dust speck.

And this is preference for fuzzies over utility, inability to shut up and multiply.
