How would you ever persuade people to respect principles underlying the law when you fail to punish people who are the law?

Modern justice is all like this:

We know this guy perpetrated, but it was some time ago and he's well connected and it's awkward for us so we're going to "hate his sin" but without any effect on his well-being. But you, dear listeners, please behave.

Ah, on unrelated note, we jailed a poor person for 10 years for a fraction of damage because it was politically convenient.

Those are all justice problems, but you are proposing to fix them with "revenge" type solutions.

Is this maybe a cultural thing? Is vengeance a commonplace solution to problems in your culture?

Why is it revenge if passed as a law?

Indeed, recent years by Putin, Erdogan and Obama show that you can pass a lot of things as a law and everybody has to comply. To any kind of insane dung!

Unfortunately, not. Because in my culture, the commonplace handling of problems is not solving them but just piling up and then dying when they topple over.
