Would the existence of the Executioner's Sword disrupt the fundamental balance of societal justice?

This article uses legal philosophy to examine the "Executioner's Sword" — an absolute, irreversible weapon wielded by Hiromi Higuruma in the anime Jujutsu Kaisen. By exploring the intersection of legal theory and story analysis, it questions whether such a weapon of absolute power could ever exist in a fair society. The paper argues that an irreversible weapon like the Executioner's Sword disrupts the legal system and ruins societal justice. By examining real-world debates surrounding the death penalty and comparing them to the absolute authority of Higuruma's domain judge ("Judgeman"), the study shows how dangerous this mechanism would be in real life. Ultimately, the article proves that when strict law is separated from human fairness and mercy, justice turns into pure violence, showing that tools of absolute termination destroy the balance needed to uphold the Rule of Law.
