Perhaps. But I have a spiritual interest in my preacher. Can I go out and avenge his death? What about the economic interest I have in my butcher or bartender?
I have family. I will be very upset if someone hurt them. I do whatever I can to keep them safe. But if something happens, revenge is about satisfying me, not satisfying them or gaining justice.
Sure, and I am not sure that PDAs will be judged on their ability to satisfy dead clients, as much as protect live ones. That is to say, people will probably be more interested in signing up with LS Defense Services, if I keep my clients from getting killed, as opposed to having a kickass payback record on people who murder my clients. Maybe deterrence will be a big part of protection, but even in that case, the end is not to buy revenge service, but survival service.
If presented with the service option of killing the person who murdered one of my family, or chasing restitution for such act to provide for dependents, which would people be more likely to choose? I would rather someone provide restitution, because it protects the living, than try to seek justice for the dead, but that is just me.
This is what I am talking about when we move to a more libertarian conception of justice. For sure, emotion is inseparable from man, but it is a balancing of emotion with reason, that is the foundation for libertarianism. When we can recognize our best interest may not be the high time preference immediate emotional response.
I used to believe that line from RATM, “Anger is a gift” (hope I sourced that properly edit nope, may have been Malcolm X). But then I watch these G20 protests, and I realize that anger is just wasted energy. It is exactly the way the state wants us to respond. It is a way to get us to misdirect ourselves from improving our situation, and instead investing in a dead end.
I feel the same way about revenge.
