Final answer:
Kwaku's persistent disregard for others' rights and lack of remorse suggests he may have antisocial personality disorder, which can only be diagnosed by a mental health professional.
Step-by-step explanation:
Based on the description of Kwaku's behavior, which includes chronic violation of the rights of others, deceitfulness, manipulativeness, impulsivity, a lack of remorse for misdeeds, and frequent issues with the law, it seems that Kwaku's personality is best accounted for by a diagnosis of antisocial personality disorder. This disorder is characterized by a pervasive pattern of disregard for and violation of the rights of others. Individuals with antisocial personality disorder often have a history of conduct disorder in childhood or adolescence and demonstrate behaviors that are unlawful, deceitful, impulsive, and reckless. It's important to note that a diagnosis of this kind can only be made by a qualified mental health professional following a thorough clinical assessment.
