Healthy individuals would feel remorse if they lied, stole, cheated or disrupted relationships, made someone lose their job or did anything else to harm another. A person with NPD, sadly, doesn't share this capacity.
Oftentimes, you can spot a highly narcissistic individual by the way she relates to others. She is smooth, charming and fun. She is haughty and arrogant with a highly inflated self worth. This comes with an extreme sense of entitlement. She may expect many "favors" from her friends, in exchange for the time you get to spend with her.
Relationships with a narcissistic individual are always one way. If you work with a NP-disordered woman, don't be surprised if she tries to undermine you on the job, or even steal your ideas in order to pass them off as her own. Don't make the mistake of trusting her with sensitive information either.
"Covert" narcissists are more difficult to discern. But they're just as dangerous, if not more so, because they appear so humble and giving. You may entrust them with your most precious secrets, which can then be used against you.
Not every woman who mistreats another suffers from narcissistic personality disorder. But this condition is fairly common, affecting an estimated one of out every 25 people. Malignant narcissists and people who bully others have many of the same traits as sociopaths.
