Medical (and other) interventions that are effective on children are judged as more valuable than those that are effective on the extremely elderly due to the concept of "quality adjusted life years" (QALYs)[1]. Of course, people's emotional reaction to children being killed is merely based on evolutionary adaptedness, and has nothing to do with whether its morally justified for them to feel a particular level of outrage.
