Morality has two key features: (1) moral judgments are not solely determined by what your group thinks, and (2) moral judgments are often applied to members of other groups as well as your own group. Cooperative motives do not explain how young children reject unfairness, and assert moral obligations, both inside and outside their groups. Resistance and experience with conflicts, alongside cooperation, is key to the emergence and development of moral obligation.
(1) 道德判断不仅仅取决于你所在群体的想法；(2) 道德判断往往不仅适用于你所在的群体，也适用于其他群体。合作动机并不能解释为什么幼儿会拒绝不公平，以及主张群体内部和外部的道德义务。与合作一样，对冲突的抵制和体验是道德义务出现和发展的关键。
