There is also this book - "Confessions of a Sociopath by M.E. Thomas" which seemed to be popular a few years ago. It's unclear how reliable the narrator is but I remember it had a jarring effect on me:
There are a couple good books about Sociopath/Psychopath if anyone is interested.

The Psychopath Test: A Journey Through the Madness Industry @

Confessions of a Sociopath: A Life Spent Hiding in Plain Sight @

I highly recommend both of these, since they are a very interesting read.
