The Judge Kings of the Underworld in Hades are none other than Minos, Rhadamanthus, and Aeacus. They are not perfect people when they were alive, but they were just rulers when they were alive. They are the sons of the God King Zeus and a mortal woman who was a princess during her time.
All of the kings died as demigods, but they were given the position of judges of the underworld by their father. The God of Death Hades thought that this is a way for his brother to monitor him, but he could care less. The God of Death Hades accepted the help since the number of deaths kept increasing.
