Many people see themselves in various groups (member of the population of their home country, or their social network), and feel justified in caring more about the well-being of people in this group than about that of others. They will argue with reciprocity: "Those people pay taxes in our country, they are entitled to more support from 'us' than others!" My question is: Is this inconsistent with some rationality axioms that seem obvious? What often-adopted or reasonable axioms are there that make this inconsistent?
Oh, I certainly agree, but who are we to decide how others value dying relative to other goals. Their utility function ain't faulty just because we call its features memetic hijacking.
