Above all, the narcissist has a grandiose sense of their own worth and value to the world around them. As such, they feel and act that "normal" rules don't apply to them. If they need to lie or cheat to get what they want, that's okay because they are important enough. Empathy doesn't interest them because it doesn't further their needs. In essence, everything is negotiable—from laws to basic manners. If it doesn't suit their needs, they feel it doesn't apply to them.
