I know - I’m saying it should be. Vengeance is a critical social regulator in human societies, but it has been damped to the point of total dysfunction.

The biological instinct for vengeance solves a social coordination problem - namely, the stability of altruistic punishment, where you make a sacrifice (such as spending resources fighting someone who wronged you rather than capitulating and moving on) to protect other people.

Modern liberal capitalism has done too good a job of suppressing higher-order social optimization instincts like vengeance, while leaving first-order selfish optimization instincts like profit-seeking in place. I don’t think this is necessarily an inherent problem in capitalism, but the current implementation won’t let you do things like this in most cases. If you go after a patent troll instead of settling, your shareholders will sue you.
