Any Juujika heads in here, have you heard of this series in some form or capacity? It went for around five volumes. It was drawn and written by Kishimoto Seishi, brother to Masashi Kishimoto (Naruto). The general premise is a dystopia Japan where crime rate has gone over the roof to the point that a law that actually existed from the Sengoku and Edo periods, the Vengeance Act - was introduced as a form of capital punishment instead of the standard hanging. In this setting, death sentences are carried out in ways that must be 1:1 to what the victims suffered. Family members of the victims would be in attendance, wearing VR visors while a task force known as the Sukedachi / Avenger 9 are entrusted to carrying out a Vengeance Execution. 

It's a far more idealistic and poetic take on what Juujika was going for. First chapter goes on about shit about "bonds of our loved ones" and later "saving the souls of both the families of the victim and the culprit" or whatever. Hell, it even goes with the "If you do that you'll become just as bad as the killer" bit but with a twist. In the second image (from the 2nd chapter of the manga), the husband of a wife who was dismembered by some crook wants to exceed the number of wounds inflicted in the original crime that took place with one of the Avengers present in the observation chamber going "Your heart will be the same as the killer's!" It's a lot more black and white compared to Juujika but simultaneously, somehow far less ruthless given that the punishments enacted on even common crooks in Juujika are made so that they suffer far worse than their victims. The violence isn't as graphic as Juujika's too.

It ended early but I wish we had gotten some interesting fights or cases from it; given later Vengeance Executions in the manga become more akin to battle shonen. Hell, the one of the cases involves a newbie in the Avenger task force having to execute an old man who basically stabbed three punks who tortured/killed his dog. Old man was fearless and was one of the more sympathetic convicts but the system worked mostly in favor of the bereaved.
