They have absolutely no remorse for other people “whom they regard as morsels to be voraciously consumed and the remnants discarded” (Simon 3). Large studies in the United Kingdom and elsewhere around the world have initially discovered that “early-onset condition is highly hereditary, hardwired in the brain—and especially difficult to treat” (Hagerty 4). This statistic ties back into the argument that serial killer’s brain abnormality predominantly affects their callous behavior. Kent Kiehl, a psychologist at the University of New Mexico, has scanned the brains of hundreds of inmates and chronicled the neutral differences between average violent convicts and psychopaths (Hagerty 4). In his study, he had found that the psychopathic brain has at least two natural abnormalities, the first appearing in the limbic system that processes the emotions (Hagerty 4-5). Someone with an oversized or under active amygdala may not be able to feel empathy or refrain from violence (Hagerty 5). Primarily, a psychopath may come to conclusion intellectually that what he or she is doing wrong, but they lack the ability to feel …show more content…

Villainous serial killers explain their contradictory behavior as out their personal control, constructing themselves as victims of circumstances that were beyond their control (Henson and Olsen 13). Many psychopaths “articulated a biological defect that prevented the normal experience of remorse or an awareness of the severity of their actions: thus, they determined their actions to be a biological imperative” (Henson and Olsen 14). Jeffrey Dahmer, by way of illustration, contended that he was wholly aware of his anomalous behavior, but was physically unable to control it. Serial killers use biological aliments as excuses for the “enacted deviant identity, thereby rejecting the stigma of the evil, predatory, purposeful killer” (Henson and Olson 14). Ultimately, it is the inborn disease that affects their lack of control over the deviant self (Henson and Olson 14). Psychopaths
