Can we say “personality disorder”?

Boss, Carl said smoothly, if Laura had cancer and she was going through chemotherapy...and lost her hair and stuff...and she was down to skin and bones and was pale and weak...Boss, would you blame her for having her disease?
False analogy in the sense that cancer is nothing like any of the Cluster B Personality Disorders like Borderline personality disorder, Histrionic personality disorder, Narcissistic personality disorder or Antisocial personality disorder which have consistent, long-term, and unhealthy patterns of thinking, feeling as well as undesirable or self destructive behavior.
Behaviors such as deceitfulness and manipulation are used for personal gain, lack empathy, extremely negative reactions to criticism, elevated sense of self-importance, strong sense of entitlement, a false sense of intimacy, impulsive and reckless behavior such indiscriminate sexual behavior and/or addictive Hyper-sexuality. People with Cluster B Personality Disorders are rampant among cheaters like Laura.
Personality disorders are likely caused by a combination of genetics and environmental factors. One study found a strong correlation between borderline personality disorder and history of sexual trauma. Another study found a link between children who were verbally abused by their mothers and various personality disorders, including borderline and narcissistic personality disorders. A recent review also found similarities in the anatomic features of the brains of people with cluster B personality. This suggests that brain development may also contribute to these disorders. Research has found a significant link between cluster B personality disorders and family history as well. Having a parent or sibling with a personality disorder increases your risk for developing the disorder.
Cluster B Personality Disorders have no cure. Psychotherapy is typically a key part of any treatment plan and cognitive behavioral therapy (CBT) which focuses on problem solving and teaches the skills to identify problematic thoughts and beliefs.
Therapy does not guarantee individuals will not have episodes or triggers and fall back into self destructive behavior Which means Laura will most likely lapse back into indiscriminate sexual behavior at some point in the futures.
Just because he wouldn't blame Laura for her for having Cluster B Personality Disorder it does not mean that she'd make a good life partner with her disorder going forward. He has to ask himself if he wants to live with her when she goes through future episodes of indiscriminate sexual behavior again. Having the disorder does not excuse nor forgive her behavior. In criminal cases having a mental disorder does not exclude the person from conviction and punishment. Neither should it be an excuse for infidelity or cheating and subsequent consequences.
