Deception constitutes a very entertaining game for psychopaths. They use one victim to lie to another. They use both victims to lie to a third. They spin their web of mind-control upon all those around them. They encourage antagonisms or place distance among the people they deceive, so that they won’t compare notes and discover the lies. Often they blend in aspects of the truth with the lies, to focus on that small grain of truth if they’re caught.
The bottom line remains that psychopaths are malicious sophists. It really doesn’t matter how often they lie or how often they tell the truth. Psychopaths use both truth and lies instrumentally, to persuade others to accept their false and self-serving version of reality and to get them under their control. For this reason, it’s pointless to try to sort out the truth from the lies. As M. L. Gallagher, a contributor to the website lovefraud.com has eloquently remarked, psychopaths themselves are the lie.
