Your line of thinking here is that he is too rigid in his thinking to recognize what he's doing.
Yes, he is single-minded, undoubtably. He also remains that way throughout the story. So, yes, there is an argument to be made that his single-mindedness is the root cause of all the problems. It's a workable theory down to the Concern level in the OS, but it doesn't really hold after that.
Still, it goes to show that we can define individual characters pretty well one way, if we look at them in isolation.
The balance I keep referring to is the Universe -- imagine a Calder sculpture with all the parts balancing out the other parts. It's hard to see the story any other way now that I see it like this.
