I ask four questions: (1) Why should we think that our hominid ancestor's predation is not just a causal influence but the main causal factor responsible for human cruelty? (2) Why not think of human cruelty as a necessary part of a syndrome in which other phenomena are necessarily involved? (3) What definitions of cruelty does Nell propose that we operate with? And (4) what about the meaning of cruelty for human beings?
