No, my view is that society intrinsically functions on forms of justice being enforced outside of the legal system. And that is how it has to function because the legal system is necessary but not sufficient for a fully functioning civil society.
And, once more, you have enforced those non-legal forms of justice many times over your life and so arguing that that it is wrong to do so is arguing that you are yourself wrong for doing so.
If “justice” was only ever enforced via the courts, people would be doing and allowing all manner of horrible things. Which I admit they are now, unfortunately, but at even higher rates than we see now.
It is a pretty universally established fact in sociology that “justice” is not merely enforced through formal systems created and administered by state entities. And that it can’t be, as formal systems aren’t sufficient in themselves to maintain functioning civil societies (they are not large enough, robust enough, or present enough to do so).
Literally all evidence supports that.
It is not an argument against legal systems and state enforced justice. It is merely an acknowledgment of the nearly universally accepted reality that civil societies require other forms of “justice” to function, as well. And all societal consequences cannot be simply predicated on whether someone has been found legally guilty in a state administered legal system.
If that were the case, most offences would never be punished in any way, whether breaking off ties with someone that has abused or mistreated you, or consequences being enforced with the likes of Jimmy Saville.
You are a member of a civil society, you have enforced consequences on others that have never been found guilty in a court of law of the offence you are effectively punishing them for, so I don’t really understand why we are even arguing this point.
