It's been awhile since I've seen the movie, so maybe Ozymandius did show traits of Hare's definition of the psychopathy. However, the article seemed to imply that the only thing that separates a psychopath from a narcissist is empathy level:
>What makes Ozymandius the villain of the story is that, while many NPD sufferers have decreased empathy, Ozy's lack of empathy borders on full-blown psychopathy
In other words, a psychopath would just be a narcissist with even less empathy, which isn't really the case. In fact, aggressive narcissism is just one of two factors in Hare's checklist. On the second factor, socially deviant lifestyle (which includes traits like failure to plan ahead, poor self control, impulsiveness, etc.), he would probably score pretty low, and thus would be unlikely classified by Hare as a true psychopath.
The description of The Comedian as having ASPD was well-justified though, other than the term "sufferer". Most sociopaths actually consider themselves to be "free" of many of the emotional and social burdens that the people they prey on seem to carry (which ties in to their narcissism).
