Psychopathy“Psychopathy is a personality disorder characterized by an inability to form human attachment, aggressive narcissism, and antisocial behavior defined by a constellation of affective, interpersonal and behavioral, most of which are perceived by society. as a pejorative” [1]. Some of these characteristics include irresponsibility, grandiosity, cunning, deception, selective impulsivity, sexual promiscuity, lack of empathy, etc. Psychopathic people not only exhibit antisocial behavior, but also emotional deficiencies such as lack of guilt. They are capable of preying on others using charm, deception, violence, or any other method that allows them to get what they want. An important characteristic of most behaviors exhibited by people with psychopathy is that they are primarily instrumental in nature. They are extremely goal-oriented and desire to acquire wealth, sexual opportunities, and increased status. Psychopathy was first described by the psychiatrist Philippe Pinel in the early 19th century. He called it "madness without delusion" and described individuals who suffer from it as "morally neutral." In 1941, Hervey Cleckley wrote a book “The Mask of Reason” which is today considered the cornerstone of the study of psychopaths. He wrote that the psychopath is capable of "hiding behind a perfect imitation of normal emotions, keen intelligence and social responsibility, a seriously handicapped and irresponsible personality." This supports the theory that not only is talk therapy inadequate as a treatment, but instead has the potential to make the situation worse, because it allows the individual to practice the art of manipulation . Today, around the world, we use a checklist in the middle of a sheet of paper to study criminal behavior. Research has shown that psychopathy is a strong predictor of violent recidivism and dangerousness. Understanding psychopaths' minds, their personalities, and their behavioral traits allows authorities to design strategies that will likely work with them. Psychopathy has been described as "the most important clinical concept in the criminal justice system." And even more recently, it is considered "the most important forensic concept of the early 21st century." Despite the lack of a cure, many new theories are still being developed on how to better identify and manage the problem. REFERENCES[1] Jacqueline B.
