McCarthy's moral vision

First off, I agree with the clip on the cover of the novel that this is a novel about regeneration through violence. A very common, it seems, theme of his works in general. I also love how, every once in a while, his narrators extoll upon the basic human capacities to know or not know the capacity of the human heart. For instance, I believe in chapter 2, he has a paragraph that asks, in general, what is in the midst of a man's heart? (I think this is right when the hermit holds up the dessicated heart to him while they sit next to the fire). This little treatise on the heart, immediately brings to mind the short story of Flannery O'Connor, when a rambling, one-armed handyman, on his way to seducing an old crone's daughter, asks the very same questions about how possible it is to see into the heart of a human being. That story was called "Good Country People"....
