I was thinking more of "Blood Meridian," but it's definitely true that "The Road" tackles a lot of similar themes albeit on a more personal and isolated scale.
I think "No Country" also is a continuation of said themes, with Anton Chigur as a sort of modern incarnation of The Judge. He must own everything. Nothing can be allowed to exist or happen save by his dispensation.
He is an amoral archon, as is life and the universe itself. He is offended only by those who refuse to acknowledge and countenance the cruel and arbitrary nature of reality itself.
Decisions and random facts of chance have permanent consequences, none of which can or should be escapable. It's offensive to The Judge/Anton Chigur that anyone might imagine otherwise.
Korematsu is the name of the SCOTUS case that allowed for the internment of Japanese Americans during WW2.
Since then it's widely been viewed as a terrible and deeply shameful decision and is taught in law schools as a textbook example of how SCOTUS power can go badly wrong, especially during times of war.
