We idealize justice as blind and impartial. You see the way we personify justice? As Justitia, a woman wearing a blindfold while holding scales and a sword. Justice is hardly blind.
In some cases, we seek to totally circumvent the necessity of man made law by believing that justice is a universal law that is enacted with or without direct action by humans. This is partially true in that there are consequences to certain actions that don’t require humans. And those consequences often aren’t of a moral nature. But more often than not, those we define as wrongdoers don’t always get their comeuppance without human intervention. This is another important lesson of Jupiter in Libra.
