Psychopathy, in both the mental health and criminal justice systems, has emerged as one of the most important clinical constructs of the 21st century (Hare, Clark, Grann and Thornton, 2000, p. 623). Where clinically, psychopathy is traditionally described as a combination of socially deviant behaviors and personality traits. Some traits and behaviors that a psychopath possesses are commonly known, for example, being impulsive, selfish, aggressive, lacking remorse, shame, feelings for others, lying pathologically, and having asocial or antisocial behaviors (Hare, & Neumann, 2006, p. . 59-60). One reason why psychopathy has seen an increase in the development of its theoretical and applied interest is the widespread adoption of valid and reliable methods in its measurement (Hare et al., 2000, p. 623). This is largely due to Dr. Robert D. Hare's recent psychopathy assessment tool called the Hare Psychopath Checklist-Revised (PCL-R) (Hare et al., 2000, p. 623). Most research dealing with psychopathy to date has been based on North American samples of forensic and criminal psychiatric patients (Hare et al., 2000, p. 623). In this essay I will use the PCL-R as an assessment tool to classify Theodore Robert “Ted” Bundy, one of the most famous American serial killers, as a psychopath. I will do this by first discussing Hare's PCL-R and its strengths and then point out the specific traits and behaviors described in the PCL-R, which are seen in Ted Bundy from accounts of his personal and criminal life, to demonstrate that Bundy was a psychopath.Hare's Psychopath Checklist-Revised (PCL-R) provided clinicians and researchers with a common metric for evaluating the psychopath......middle of article......ud, Aynesworth and Bundy, 2000 , P. 28). Bundy also felt no remorse for his murder victims and in several cases took trophies of his killings, decapitating his victims' corpses with a hacksaw or removing their hands to keep in his home (Ramsland, 2013, p. 21) . All in all, if Ted Bundy had been evaluated for psychopathy using Hare's PCL-R, when he was on the trail of his crimes, in just the few traits and behaviors that were seen prominently in his life, he could certainly have fallen into the category of a psychopath. If he had been identified as a psychopath, evidence suggests that the diagnosis of psychopathy could result in a harsher judicial sentence or could even be used to justify the imposition of the death penalty rather than life imprisonment (Fine & Kennett, 2004, p. 425). . However, even without this diagnosis, Ted Bundy was still sentenced to death for his crimes.
