Thank you for your comments. This gives me the opportunity to explain Sadism. And how it blends in with other personality disorders. The following reference is from Wiki:I am honored to have this much power and control over you. <quoted text>
Sadism is a behavioral disorder characterized by a callous, vicious, manipulative, and degrading behavior expressed towards other people. To date, the exact cause of sadism is not known clearly. However, many theories have been given to explain the possible reasons underlying the development of a sadistic personality in an individual.
Sadism involves gaining pleasure from seeing others undergo pain or discomfort. The Opponent-Process Theory explains the way in which individuals not only display, but also take enjoyment in committing sadistic acts. Individuals possessing sadistic personalities display recurrent cruel behavior and aggression. Sadism can also include the use of physical and emotional cruelty, purposefully manipulating others through the use of fear, and a preoccupation with violence.
While some sadistic individuals do gain pleasure in imposing pain and suffering upon others, sadism does not always involve the use of physical aggression or violence. More often, sadistic individuals express aggressive social behaviors and enjoy publicly humiliating others in order to achieve a sense of power over them.
Sadistic Personality Disorder is often found to occur in unison with other personality disorders. In fact, studies have found that Sadistic Personality Disorder is the personality disorder with the highest level of comorbidity to other types of psychopathologic disorders. However, sadism has also been found in patients who do not display other forms of psychopathic disorders. One personality disorder that is oftentimes found to occur alongside Sadistic Personality disorder are Conduct Disorders. In addition, anti-social and narcissistic personality disorders are sometimes found in individuals diagnosed with Sadistic Personality Disorder. Other disorders that are also oftentimes found to exist with Sadistic Personality Disorder include Bipolar Disorder, Panic Disorders, Depression, Borderline Personality Disorder, Histrionic Personality Disorder, Obsessive Compulsive Disorder, Self-Defeating Personality Disorder and Passive-Aggressive Personality Disorder. Studies have found other types of illnesses, such as alcoholism, to have a high rate of comorbidity with Sadistic Personality Disorder.
Because of its high level of comorbidity with other disorders, researches have had some level of difficulty distinguishing Sadistic Personality Disorder from other forms of personality disorder. While Sadistic Personality Disorder itself is no longer included in the DSM, partially for this reason, other types of disorders involving sadism, such as sexual sadism, are still found in the DSM.
Most of these theories commonly point out the fact that sadism is mainly dependent on the upbringing of an individual.
