No, most people born under the zodiac sign of Libra are not narcissists. Narcissism is a personality disorder, not a zodiac sign. Narcissistic personality disorder is characterized by an inflated sense of self-importance, a need for admiration, and a lack of empathy. While anyone can develop narcissistic personality disorder, regardless of their zodiac sign, there is no evidence to suggest that people born under the sign of Libra are more likely to be narcissists than people born under other zodiac signs.
