Law suit, but generally arbitration of some kind (the conceptual kind, not the legal term). Part of the social contract is that we don't resolve our own disputes beyond a certain level of seriousness, we allow neutral third parties to do so. Otherwise we'd have fights in the streets and mob justice.
It works a hell of a lot better than "alternative methods" from a moral standpoint, however. The reality is that people have just become more okay hurting others.
Nah. Violence is the underlying motivation behind a lot of the world. Whether implied from people not following "the process" (your social contract), or people working around process that aren't working for them (corruption, etc).
There's no better moral standpoint in either, it's always a case by case basis.
I did and sorry, it honestly seems like you've never considered any of this before whenever you wrote what you did, and generally have zero clue what you're talking about.
