A personality disorder is not the same as a personality trait. A personality disorder is a disturbance in normal personality functioning, but it doesn't lock you into having one personality. People with NPD have a great variation in individual personality traits. A personality disorder diagnosis is determined on the basis of fitting a list of criteria, it's not a judgement of someone's entire personality.

Additionally, the article you linked says one of the leading indicators of criminal behaviour is "psychopathy". Psychopathy is not a personality trait, nor is it even a recognised psychological term. Although I'm short on time, I have serious doubts about that review's impartiality and proper use of the scientific method.

Finally, discriminating against people because a statistical model says they're more likely to commit crimes is some Minority Report bullshit, and it's also exactly how police treat black people. Profiling is wrong.
