One very interesting aspect of the psychopath is his “hidden life” that is sometimes not too well hidden. It seems that the psychopath has a regular need to take a “vacation into filth and degradation” the same way normal people may take a vacation to a resort where they enjoy beautiful surroundings and culture. To get a full feeling for this strange “need” of the psychopath – a need that seems to be evidence that “acting human” is very stressful to the psychopath – read more of The Mask of Sanity, chapters 25 and 26.
Also, read Cleckley’s speculations on what was “really wrong” with these people. He comes very close to suggesting that they are human in every respect – but that they lack a soul. This lack of “soul quality” makes them very efficient “machines.” They can be brilliant, write scholarly works, imitate the words of emotion, but over time, it becomes clear that their words do not match their actions. They are the type of person who can claim that they are devastated by grief who then attend a party “to forget.” The problem is: they really DO forget.
Being very efficient machines, like a computer, they are able to execute very complex routines designed to elicit from others support for what they want. In this way, many psychopaths are able to reach very high positions in life. It is only over time that their associates become aware of the fact that their climb up the ladder of success is predicated on violating the rights of others.“Even when they are indifferent to the rights of their associates, they are often able to inspire feelings of trust and confidence.”
The psychopath recognizes no flaw in his psyche, no need for change.
