Justice of Lycurgus; what use would it be today and how might it changer USA criminal justice?

Lycurgus was a Spartan Leader and law giver. A youth once injured him (removed one of his eyes) and according to the Spartan law was rendered unto him for whatever punishment he, Lycurgus , saw fit to inflict. Lycurgus took him home and inflicted the most sever of all punishments upon the youth – Lycurgus educated him. A year later Lycurgus brought him before the assembled Spartans and said: “When you gave me this young man he was filled with hate and violence, I return him to you fit to serve his nation.”
