Does a narcissist have conscience?

The answer is: No

Explanations:

Narcissism is a personality disorder characterized by an inflated sense of self-importance, a need for admiration, and a lack of empathy for others. People with narcissism are often unable to feel guilt or remorse, and they may have difficulty understanding the feelings of others. A conscience is a feeling of right and wrong and is generally lacking in people with narcissism.
