The Judicator is the reaction of Covenant leaders after the end of the Human-Covenant war. The Judicator is selected much like the Arbiter was, a warrior fallen from grace is selected to fulfill a suicide mission. However, the Judicator is used to show a high moral standing, to show that failures can become successes. Therefore the Judicator is seen in the eyes of the Covenant soldiers how the Spartans are the humans.
