Interesting analysis. I’m not a big TV guy, so I haven’t seen any of the episodes, but I’d have to watch one of the hundreds of hour-long edgy drama-type of series, this would be at the top of the list.
A few things though, that the video mentions: justice can’t be objective because people aren’t objective. We can’t be. That there’s an ephemeral form of a perfection called “justice” existing somewhere, waiting for us to conform to its nature, is perhaps a nice, inspiring thought, but that’s as far as it goes. Sorry, Plato. There can’t be one rule, or set of rules, to govern the whole of humanity because we don’t know all of humanity. In short, justice is best administered by someone intimately connected with us. This is at total odds with most westernized systems, so I wouldn’t expect too many people reading this to consider this a workable option.
The other thing: sometimes it’s irrelevant whether someone is “morally culpable” for their actions. Serious threats to social cohesion, in some contexts, don’t need to be “understood” for physical force, in the form of defense, to be available as a moral option. Social cohesion by itself, as an innate need of the human condition, demands it.
