From a 2013 definition of a sociopath: "These kinds of liars tend to live in their own little world and always find ways to justify their dishonest deeds. They do not respect others and place their own needs first and foremost.

If someone questions the sociopath’s lies they can be incredibly devious in the way they cover things up. This can include placing the blame at someone else’s door or by inventing complex stories to cover up their untruths.

It is believed by some experts that sociopathic lying is connected to the mental illnesses Narcissistic Personality Disorder (NPD) and Antisocial Personality Disorder (APD).

If you come across someone who you think is a sociopathic liar, beware!"
