Disorders: Antisocial personality disorder. Narcissistic personality disorder Scar's aggression towards his brother Mufasa goes far deeper than simple sibling rivalry; it stems from the deep rooted symptoms of his antisocial personality disorder, traits which can explain many of his 'despicable' actions. Scar has utter disregard and violation of the rights of others, he doesn't think twice about luring Simba into a trap that will kill him or throwing his brother off the cliff to his death. Added to that we have Scar's deep-seated narcissism; he is fiercely devoted to his own thirst for power. He might be aware of the destructive force of his power struggles on those around him but it doesn"t matter to him. As for his tyrannical leadership of the hyena population; Scar is arrogant and demanding and he expects everyone to follow his every whim, something that becomes apparent when he replaces his dead brother as king of the pride. In The Lion King, Scar simply didn't care about the wide-spread damage caused to the pride lands; if anything he was proud of the death and devastation, although a distorted view of action and consequence meant he didn't have the foresight to see that this would lead to a lack of food supply. A king, Scar most definitely doesn"t not make.
