Seems these professionals get a lot of hate. What do you see a lawyer's and a judge's job to be?
A lawyer's proper role is to remember people of ethical dilemmas and considerations. It should not be accepted by any society for it to be paid. Specifically, earning a living out of it is inherently immoral and should be punishable to an extreme.
A judge's role is to arbitrate some resolution for pending conflicts. It is ultimately of lesser importance whether those resolutions approach fairness, because it is unreasonable to expect them to be. Judges can only know so much of the circunstances and ethical dilemmas of a decision. Despite the common misconception, it is actually legal arbitration that is blind, or at least imperfectly aware of relevant considerations. Justice proper is by definition not blind, but perhaps unattainable and only in very fortunate and
rare circunstances at all related to judicial systems.
Which is a reason not to lend a lot of significance to those judicial systems. But I suppose the mythical expectations of people making the world acknowledging of "our rights" are just too much of an allure.
Quite frankly, that is one of the major tragedies of humanity's history.
How do lawyers and judges fulfill this role?
Protected and twisted by deep layers of msiplaced expectations, unfortunately.
Are these professionals ethical?
Of course not. Lawyers, particularly,
can not conceivably be at once profesional (as in, earning a living by their activity) and ethical.
Judges are an interesting case. The activity itself is very much needed, but the aura of importance lent them is immoral. Regardless of appearances, they are actually victims of the expectations of their societies... albeit privileged and often corrupted victims.
Are unethical judges and lawyers prevalent? How much so? How are they so?
I maintain that profesional advocacy is a shortcut to moral corruption. Inherently so. That is a direct result of them being paid to represent people's interests while being protected from paying the price for lying while at it. You might as well threat them with death if they do not become corrupted. No, scratch that, it would be better to.
Judges are slightly better, but not nearly enough to bring much hope. It is not healthy to expect a human being to hold so much power and somehow be fair while so doing.
Finally, would we be better or worse without them? Why?
Judges we need outright, but we should strip them of much of their power and ourselves of nearly all of our expectations about them.
However, it is conceivable that they might be substituted by a random system of some kind, perhaps. The challenge is in finding practicable ways of representing the decisions in such ways that the conflicted interests accept the random decisions.
Lawyers should probably be outlawed, ironically enough. Or more exactly, it should be fiercely forbidden for people to be paid for advocacy.
