M. E. Thomas (a pseudonym) has a blog, Sociopathworld.com. She is a law professor, a practicing Mormon, and not a convicted criminal. Her memoir is a chilling read. Since Sociopaths are such liars, one thinks twice about her seeming honesty about her condition. She attributes her ability to function in the world of empaths to her family, albeit disfunctional, but structured and loving in its way. She gives the history of the psychology world in defining this condition, which is now gravitating toward calling it Antisocial Personality Disorder. In truth the condition is a continuum, but none the less scary.
Of these three books, this one lets you into the mind of a functioning sociopath the best!

Our psychopaths cull out the weak in the same way that predatory big cats catch the weakest wildebeast.
