Well, and it's true to the diagnosis of psychopath. If he really is broken, he's "incapable" of feeling. There is no healing, no breakthroughs, no progress. He literally doesn't have the machinery to experience emotion the way the rest of society does.

And that's what drew me so powerfully to the character. Especially Harry's very careful lessons on how to fit in, how to "pass" for normal.

What's next? Feeling guilty for taking out the trash?
