Anti-social personality disorder VS narcissistic personality disorder

Anti-social by far. However I can't elaborate on why.

You can't compare disorders like this. Both cause misery... thats enough

Well, which one would you be more concerned to have around? Someone who won't think twice about using you, hurt you, put you in danger, couldn't care less how their action affects others and can just go off at any time or an asshole who thinks he's the best person in the world? I'll take deluded over dangerous without a second's thought...

sociopaths are the most dangerous kind of people there are, bar none.
