Sociopaths are very egocentric

Sociopaths are very egocentric individuals that lack a sense of personal responsibility and morality.
 "...They may be impulsive, manipulative, reckless, quarrelsome, and consistent liars."
Sociopaths are usually unable to sustain relationships and have a total lack of remorse for their actions AND may also be very prone to aggressive, hostile, and sometimes violent behavior.
This aggression may or may not lead to criminal behavior and often takes the form
of domestic violence. Along with these other actions, sociopaths often engage
in self-destructive behavior such as alcoholism or addiction to drugs.  This, of course, usually worsens many aspects of the sociopathic behavior. Despite these previous symptoms, the sociopath may be an excellent actor, always appearing charming, calm, and collected. They usually have a normal or above normal intelligence level and good verbal fluency. It is these qualities that sometimes place he sociopath in leadership positions within their social groups and often make it hard to spot their "black side." 

An individual who is antisocial because he breaks SOCIAL NORMS which either land him in legal trouble, or result in his exploitation and abuse of others at their expense for his or her personal gain. Sociopaths generally have a criminal record and they often have a few key traits:

• They are extremely charming, manipulative, conning as they can lie and lure people, acting as their friends and then hurting them later on.
• They have less guilt or remorse due to heavy abuse, lack of concience, low serotonin levels in the brain and often acting out their whole life as a normal person when they really see people as pawns on the chessboard.
• They are compulsive liars and will say what they believe the victim wishes to hear.
• They above all deny they are at fault.  The issues in their life is always someone else's fault.
• They are often sneaky, secretive and clandestine in their persona. They hide behind fake names and often highly cryptic in their communication. They will portray themselves through social media in a pseudo-intelligent and philosphical manner. (will copy and paste lyrics to little known songs or poetry by other not known amateur poets as if it was original thought).
• Many have explosive tempers, bouts of anger and no impulse control. Theyabuse alcohol, illicit drugs, pornography and frequent strip joints and rough bars where they will throw their fist in a split second over little things. 
• They are aggresive. They will stalk, predatorize and pursue their goals very extensively, manipulating people and situations.  They will maintain that they "answer to no one" or "fear not for themselves". 
• Once their facade is seen through and they are "figured out" they will say disparging and hostile remarks as well as making threats toward public humilation or personal safety especialy when they are angered..  They attempt to dominate things and bully others to get what they want.   
• They respect no boundaries socially or morally.  They will work hard to break up a marriage simply to say they did.  However, Sociopaths are highly promiscuious thus  have severe trouble in relationships.  One reason is they lose interest quickly once they have accomplished the "conquest" and the other reason is that the other person quickly begins to see the psychological impairment whether through the lying or through violence.
• Sociopaths will have a history of failed relationships (divorce) and if children involved, due to their poor sense of responsibility, have a poor history of providing support for the children (financially, emotionally and physically).   
• The sociopath has difficulty in maintaining employment due to their disrespect for boundaries and authority.  They have a long list of meanial jobs and many choose to live "off the system" through social welfare, prison, or false disability. 

Simply, sociopaths believe that they are doing nothing wrong or doing something extremely good, due to their egocentricity and grandiose sense of self-worth.  This to justify their cold-bloodedly acquiring what they want and to do as they please at the expense of others.  They are predators who satisfy their lust for power and control through superficial charm, manipulation, intimidation, and violence.  Exposing and avoiding them is the best way to disarm them and prevent harm to others.
