Narcissists are possessed of inordinate abilities to charm, to convince, to seduce, and to persuade. Many of them are gifted orators and intellectually endowed. Many of them work in in politics, the media, fashion, show business, the arts, medicine, or business, and serve as religious leaders.
By virtue of their standing in the community, their charisma, or their ability to find the willing scapegoats, they do get exempted many times. Having recurrently "got away with it" - they develop a theory of personal immunity, founded upon some kind of societal and even cosmic "order" in which certain people are above punishment.
But there is a fourth, simpler, explanation. The narcissist lacks self-awareness. Divorced from his true self, unable to empathise (to understand what it is like to be someone else), unwilling to constrain his actions to cater to the feelings and needs of others - the narcissist is in a constant dreamlike state.
To the narcissist, his life is unreal, like watching an autonomously unfolding movie. The narcissist is a mere spectator, mildly interested, greatly entertained at times.
He does not "own" his actions. He, therefore, cannot understand why he should be punished and when he is, he feels grossly wronged.
So convinced is the narcissist that he is destined to great things - that he refuses to accept setbacks, failures and punishments. He regards them as temporary, as the outcomes of someone else's errors, as part of the future mythology of his rise to power/brilliance/wealth/ideal love, etc. Being punished is a diversion of his precious energy and resources from the all-important task of fulfilling his mission in life.
The narcissist is pathologically envious of people and believes that they are equally envious of him. He is paranoid, on guard, ready to fend off an imminent attack.
A punishment to the narcissist is a major surprise and a nuisance but it also validates his suspicion that he is being persecuted. It proves to him that strong forces are arrayed against him.
He tells himself that people, envious of his achievements and humiliated by them, are out to get him. He constitutes a threat to the accepted order. When required to pay for his misdeeds, the narcissist is always disdainful and bitter and feels misunderstood by his inferiors.
Cooked books, corporate fraud, bending the (GAAP or other) rules, sweeping problems under the carpet, over- promising, making grandiose claims (the "vision thing") - are hallmarks of a narcissist in action. When social cues and norms encourage such behaviour rather than inhibit it - in other words, when such behaviour elicits abundant narcissistic supply - the pattern is reinforced and become entrenched and rigid. Even when circumstances change, the narcissist finds it difficult to adapt, shed his routines, and replace them with new ones. He is trapped in his past success. He becomes a swindler.
