Final answer:
The term describing remorseless predators who engage in violence within the context of antisocial personality disorder is 'psychopaths'. Psychopaths represent a severe form of antisocial personality with a pattern of criminal behavior, classified under the DSM.
Step-by-step explanation:
The term in question that refers to a subgroup of individuals with antisocial personality disorder characterized as remorseless predators who engage in violence to get what they want is psychopaths. This term describes a severe form of antisocial personality disorder where affected individuals often show a pervasive pattern of disregard for the rights of others, lack of empathy, and generally a pattern of regular criminal behavior. In contrast, narcissists often showcase an excessive need for admiration and a lack of empathy, but not necessarily the violent and criminal tendencies associated with psychopathy. Sociopaths are similar to psychopaths in that they may also exhibit antisocial behavior, but their actions and behaviors are often less severe and may stem from environmental factors rather than a psychological disorder. Manipulators, while they may display traits of deceit and control, do not inherently have the violent tendencies nor the personality disorder diagnoses associated with psychopaths.
The diagnosis and classification of mental disorders such as antisocial personality disorder and its severe form, psychopathy, are found within the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychological Association. These classifications help in guiding the diagnosis and potential treatments for these disorders. Psychopaths, according to the literature, often exhibit dysfunctional cognition and reward processing, which can contribute to their antisocial and violent behaviors. The discussion of psychopathy also touches on theories such as social disorganization theory, which suggests that growing up in impoverished areas may contribute to higher instances of deviant or criminal behaviors.
