I HAVE NEVER KNOWN MUCH GOOD DONE BY THOSE WHO AFFECTED TO TRADE FOR THE PUBLIC GOOD.

Adam Smith's observation is as relevant to Game of Thrones as it is to actually existing regimes.  With elaboration by no less than C. S. Lewis.  "It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. They may be more likely to go to Heaven yet at the same time likelier to make a Hell of earth."
