Narcissistic personality disorder is characterized by an exaggerated sense of self-importance and a significant lack of empathy towards others. Individuals with this disorder often display vanity and a relentless pursuit of power, believing they deserve to dominate those around them. Their arrogance and insensitivity can lead to negative consequences for those they encounter, as they prioritize their own desires over the well-being of others.

This description of narcissism prompts comparisons to figures like Donald Trump, as highlighted in Val McDermid's book "Out of Bounds." The traits associated with narcissism—such as a superiority complex and disregard for others—are evident in behaviors that can alienate and harm those who do not align with their ambitions.
