Sociopathy
Chronic lying is a sign of sociopathy.
Sociopathy, (or as it's officially called, ASPD) is a mental disorder charecterized by failure to conform to social norms, deception, impulsiveness, irritability and aggressiveness, reckless disregard for safety of self or others, irrisponsibilty, and most importantly a lack or remorse or empathy. Sociopathy in and of itself is not a crime, most sociopaths are able to live completely fine lives without commiting crimes or getting arrested. That being said, the symptoms of sociopathy, including those listed above, make it very easy to resort to crime, which is why such a large percentage of people in jail, (sometimes up to %50) are sociopaths.
There is a variety of circumstances that can contribute to sociopathy. Some people can experience trauma and still thrive socially. Others may be deeply affected by such experiences and become depressed, angry, addicted or suicidal adults. There are many cases where sociopaths have experienced no significant trauma at all. Sociopathy is often a personality trait that may or may not be related to life experiences. If a person has a predisposition for sociopathy, any type of trauma is enough to trigger maladaptive and antisocial behavior. Many times, childhood abuse (even emotional abuse) is associated with personality disorders and sociopathy.
Sociopathy is untreatable. They do not change.
