This video answers the question: How can people that are narcissistic and psychopathic use emotions to manipulate people? What I'm really talking about here is a specific type of manipulation, where people try to elicit a specific emotion to achieve objective. We know this tends to be more associated, as a behavior anyway, with narcissism and psychopathy. Somebody doesn't have to be narcissistic or psychopathic to be manipulative. When we talk about emotions what we see is that emotions are thought of as helpful.

If we look at emotions, we see there are only six basic emotions and they are present across all cultures. The emotions are anger, disgust, fear, happiness, sadness, and surprise.
Emotions are simple, immediate, and they're constricted to really just six types, although the amount of expression would be different depending on the situation.
