What you have to understand about narcissism is that it's a primitive coping mechanism which originates in childhood, and if you are mentally aberrant and don't have a hope in the world to succeed in adult socio-sexual relationships, then it is cruel to dispel you of your narcissism and force you to confront reality -- which is not good, of course. It is much better to dwell in grandiose fantasy than to depersonalize and become suicidally despondent.
I do not fault subhumans for being narcissistic. This is the opposite view of roasties -- who fault subhumans for being narcissistic, but give Brad and Chad a pass for any of their excesses.
