The Psychopath Defined
The work of Hare and his associates clarified a set of diagnostic criteria that offers a practical approach to both the assessment and treatment of psychopathy. The PCL-R items are grouped around two basic factors, affective/interpersonal features and socially deviant lifestyle (both of which have been divided further into four facets, two each for the two factors). Refocusing the idea of antisocial personality disorder, psychopathy is characterized by such traits as
•lack of remorse or empathy
•shallow emotions
•manipulativeness
•lying
•egocentricity
•glibness
•low frustration tolerance
•episodic relationships
•parasitic lifestyle
•persistent violation of social norms
It remained to translate the academic and professional work into a form that ordinary people could understand, so in 1993, Hare published Without Conscience. His purpose was to warn people about those predators who walked among them, and to provide a way for those with shattered lives as the result of an encounter with a psychopath to deal with it. He believes that, for their own protection, it’s crucial that people learn to identify a psychopath who may be very close to them.

Casey Anthony to a tee.
Yes, it does fit Casey. Unfortunately most psychopaths have other personality disorders on top of that one. Casey is also a Narcissist for certain and perhaps histrionic or borderline as well. She does love drama and when it is lacking in her life she creates it. Normal people don’t like living a life of constant turmoil.
The Psychopath Defined
Psychopaths are actually not all that rare - they're basically people that derive pleasure from hurting others.
Those that are high functioning enough to control themselves usually become cops, politicians, CEOs and judges.
The movies have twisted the public perception of psychopaths - they're not rare and they're mostly not killers.
