From this article:
Cluster B behaviors are traits such as manipulative, deceitful, impulsive, selfish, aggressive.In a brief but original discussion, physician-philosopher Carl Elliott (1996) argued that we should hold persons with personality disorders morally responsible for their actions; he stated that "a person with a personality disorder who behaves badly ordinarily intends to behave badly, and people should generally be held accountable for what they have intended to do" (p. 70, emphasis in original). According to Elliott, a diagnosis of personality disorder is normally not sufficient for excusing a person's actions, nor do disorders or defects of character excuse. As he argued, "judgments of responsibility are essentially judgments about a connection between an agent and an action, and these types of judgments must be distinguished from questions about a person's character" (p. 58).
The central argument of this paper is that the DSM-IV personality disorders are actually comprised of two very different kinds of theoretical entities that denote two very different kinds of syndromes. Some denote genuine clinical disorders; these are the disorders in Clusters A and C. The others denote moral disorders; these are the disorders in Cluster B. The Cluster B disorders include the antisocial, borderline, histrionic, and narcissistic types. Thus, even if the Cluster B disorders are empirically valid theoretical categories, it does not necessarily follow that they are also necessarily empirically valid clinical categories.
An example of a personality disorder that falls under this criteria is Narcissistic Personality Disorder with indicators such as:
1. has a grandiose sense of self-importance
2. is preoccupied with fantasies of unlimited success, power, brilliance, beauty, or ideal love
3. believes that he or she is "special" and unique
4. requires excessive admiration
5. has a sense of entitlement
6. is interpersonally exploitative
7. lacks empathy
8. is often envious of others or believes others are envious of him or her
9. shows arrogant, haughty behaviors or attitudes
These aren't empirical symptoms that someone can be tested and diagnosed like weight gain or loss, pain, sleep disturbances, etc.
So does this guy have a point or is he not enabling the way he should?
