It occurs to me this system might set in motion a great wheel of history in which The Rebel realizes there must be laws to protect the weak, and ushers in The Good King who begins to demand conformity, which opens the door to The Tyrant, whose absolute power absolutely corrupts until The Insane Monarch makes life unbearable, which then brings a Rebel Captain along to overthrow him.
I also like the suggestion to create many different governments and work the clergy into them.
