Harming a favored side: an anomaly with supreme values and good intentions

Third-party adjudicators, be they governments, or politicians or academics, can take positions regarding who initiated a conflict, who is to blame for harm or damage, and who has violated international law. Decisions need not always be objective. There can be bias. I consider the anomaly of biased adjudicators providing incentives for harm to their favored side. The anomaly arises in real-life circumstances. The puzzle is why adjudicators with good intentions cooperate in bringing harm to the civilian population of the side with which they sympathize. Anomalies are usually addressed in a context of behavioral economics. I consider both behavioral and rational explanations.
