The distinction between a damage avoided and a benefit gained is up to a point artificial. [In most cases] the line that separates them is impossible to determine, or rather it does not exist in human feeling. When evildoers intrude on and dominate most social relationships, . . . the very act that saves one from their hostility can also bring their friendship with all its associated advantages (p. 129). … The violence of extortion and the self-interest of the 'victim' tend to merge and to provide an inextricable set of reasons for cooperation: the advantage of being a 'friend' of those who extort one's money or goods is not therefore simply that of avoiding the likely damages that would otherwise ensue, but can extend to assistance in disposing of competitors, or protection against the threats of isolated bandits, and against the risk of being cheated in the course of business transactions.
