I go into this in another comment in this thread.

But the plot does depict an ideological struggle it's just an extremely feudal one and the circle of life is almost exactly the ideological doctrine of feudalism and divine right of kings. Everyone has their assigned place and that place carries social rights and responsibilities. Circle of life is just divine right of kings. Especially considering that in feudal concepts the will of God for feudal roles was considered an aspect of nature. Scar as feudal usurper who upsets the natural order who is replaced by the true king restoring the order and thus putting nature back in balance is a very obvious theme

Personally I thought Stannis was meant to be a depiction of Cromwell that had the flaws of not understanding or caring to understand anything about Cromwell's background, motivations, or why people liked him and thus didn't really work. Some aspects of his personality are very clear allusions to Cromwell such as his exact legalism, obsession with order and the manner of his justice for example his insistence on both punishing and rewarding Davos for the onion stunt. But he just doesn't have the ideology which makes him incoherent.
