Warfare can flourish without any material stake in the conflict

Evidence

In traditional Dani culture, men from villages separated by agricultural gardens regularly engaged in intertribal warfare, one of the most socially valued activities in Dani life. The Dani did not fight for land, food, resources, mates, or the conquest of opponents. Rather, fighting served social and spiritual purposes. Dani warfare, which was highly stylized, took place in designated battlefields adjacent to the villages. — Albert Bandura, Moral Disengagement, 163
