Which personality disorder is characterized by a lack of remorse and frequent legal troubles?

Antisocial Personality Disorder is characterized by a persistent pattern of disregard for the rights of others, which often manifests as deceitfulness, impulsivity, irritability, and aggression. Individuals with this disorder frequently engage in unlawful activities and may face legal troubles as a result of their actions, such as theft, assault, or other criminal behaviors. A key feature of Antisocial Personality Disorder is a lack of remorse for these behaviors, which means individuals do not express guilt or regret for causing harm to others.

In contrast, Borderline Personality Disorder typically involves emotional instability, relational conflicts, and fear of abandonment rather than outright disregard for societal norms. Narcissistic Personality Disorder focuses on an inflated sense of self-importance and a need for excessive admiration, often accompanied by a lack of empathy, but does not necessarily lead to legal troubles. Schizoid Personality Disorder involves a pervasive pattern of detachment from social relationships and a limited range of emotional expression, which is notably different from the behavioral patterns outlined in Antisocial Personality Disorder.

Given these distinctions, Antisocial Personality Disorder is the most fitting answer for the symptoms described.
