That's why most laws have a wide band of potential punishments.

It's typically a single person -- the judge -- who will select the punishment from the band of permissible punishments. So now we're taking a theoretical group decision made across a wide swath of society, and laying it down on a single person... This is already done to a large extent, except that the judge has minimum and maximum punishments to work between.

This has huge implications on rule-of-law. I'll just link to another thread where I argued against a very similar viewpoint:

> There's a myriad of reasons why this is a bad thing for society. For example, white supremacy groups not being arrested or charged with crimes because all the cops and DAs and judges are also white supremacists. If it's truly within their world-view that a lynching is not wrong, then according to your theory it's their responsibility to not arrest or charge for it. This viewpoint is directly opposed to the rule of law.
