How would you explain the king’s “perfect“ system of justice?

The king's system of justice is perfect because only destiny and chance determine the fate of a person accused. It eliminates any kind of bias or prejudice, which could sway a jury or a judge toward mercy or severity depending on their personal feelings toward the accused. The king's version of justice does not allow for that kind of personal involvement in a case, which gives the king reason to believe it is perfect.
Though this description of the king's system of justice sounds somewhat reasonable on the surface, a closer look reveals its numerous flaws. It does not take into consideration the honesty of the accuser, nor does it take into consideration any extenuating circumstances that might explain the accused's crime. As well, chance and destiny ignore the belief in a person's free will, which might be problematic to some readers.
