There is one thing that all Sociopaths have in common that sets them apart from the rest of HUMANITY, and I can't stress it enough;
THAT THEY ARE UNABLE TO FEEL ANY EMPATHY TOWARDS ANOTHER PERSON. IT COULD BE A PARENT, CHILD, RELATIVE, CLOSE FRIEND, OR A COMPLETE STRANGER. THEY DONT UNDERSTAND FEELINGS SUCH AS LOVE, SADNESS, GUILT, WORRY ETC., EVEN WHEN THEY ARE PRESENT IN OTHERS. WHY? BECAUSE THESE ARE EMOTIONS THAT ARE FOREIGN TO THEM, SO THEY CANNOT UNDERSTAND THE REASONING TO ADAPT THEIR BEHAVIOR TO WHAT OTHERS ARE FEELING OR NEEDING AT A TIME OF CRISIS.
As we have seen, the Hierarchy of Sociopaths, is often measured by the Ability to Adapt their Behavior to what is expected. It is the Primary way of getting what they want, and the ability to remain unrecognized as Sociopathic, is how well they are able pull off this Deception.
However, keep one thing in mind. No matter how Genuine or Realistic their Behavior seems at times, especially when exhibited during times of Great Stress that others are going through, it is an Act. They are playing a Part, doing things that they believe are expected of them. The Turmoil and Emotional Mind Sets that are present among those involved in a given Conflict or Situation, are alien to the Sociopath. In Fact, the Sociopath considers such emotions as Flaws and Weaknesses, that make others Fair Game to Use and Exploit.
This leads to another Characteristic found among Sociopaths; A BELIEF THAT THEY ARE SUPERIOR BEINGS, NOT WEIGHTED DOWN BY CONSCIENCE, OR FEELINGS OF GUILT AND REMORSE. EVERYONE ELSE WHO FEELS SUCH THINGS, IS MENTALLY HANDICAPPED, AND DESERVES TO BE USED AND EXPLOITED.
Remember, that Sociopathy is not a MENTAL ILLNESS. There are no Biological or Chemical factors that have caused this World View. It is not the result of Genetics gone wild, or problems during Pregnancy. UNLIKE, THE PSYCHOPATH AND SCHIZOPHRENIC, WHO CAN BE DIAGNOSED AND TREATED, THE SOCIOPATH CANNOT BE "CURED" IN THE TRADITIONAL SENSE.
