I think of it not as being right, or good, but truly just. Justice was never about being good or right, but a manifestation of karma. Like the 'ol “If a son shall strike is father, his hand will be cut off”.
If you hold responsibility for decisions that unjustly, for no good reason, killed people, death is a just punishment.
As the one of the oldest laws of justice, “An eye for an eye”.
Reminds me that like the California roll, Philadelphia roll and ig using stuff like cream cheese, just wasn’t a thing in Japan, they are American things, but as Japense tourists came to america and had them, they started wanting them back home and some people are pissed Japense sushi is being “Americanized”
