  Against the assumption of purely self-interested behavior, we know that there are many active, more or less well funded groups that seek collective results that serve interests other than those of their own members. For a trivial example, none of the hundreds of people who have been members of the American League to Abolish Capital Punishment is likely to have had a personal stake in whether there is a death penalty (Schattschneider 1960, 26). In our time, thousands of people are evidently willing to die for their causes (and not simply to risk dying—we already do that when we merely drive to a restaurant for dinner).  Perhaps some of these people act from a belief that they will receive an eternal reward for their actions, so that their actions are consistent with their interests.
