Personally I think his talent as a wordsmith is accidental. If I attempt to read his works with the standard idea of protagonist as sympathetic character, having 'correct' pov, etc, I find his writing atrocious.

If read without that idea, then the language shows the depths of isolation and horror the mind can inflict on itself when trying to gain power over what one hates, refuses to understand and accept anything outside of self-imposed tunnel vision of unquestioning self-righteousness - then the writing becomes damned near brilliant.
