Most narcissists enjoy an irrational and brief burst of relief after having suffered emotionally ("narcissistic injury") or after having sustained a loss. It is a sense of freedom, which comes with being unshackled. Having lost everything, the narcissist often feels that he has found himself, that he has been re-born, that he has been charged with natal energy, able to take on new challenges and to explore new territories. This elation is so addictive, that the narcissist often seeks pain, humiliation, punishment, scorn, and contempt - as long as they are public and involve the attention of peers and superiors. Being punished accords with the tormenting inner voices of the narcissist which keep telling him that he is bad, corrupt, and worthy of penalty.
This is the masochistic streak in the narcissist. But the narcissist is also a sadist - albeit an unusual one.
The narcissist inflicts pain and abuse on others. He devalues sources of supply, callously and off-handedly abandons them, and discards people, places, partnerships, and friendships unhesitatingly. Some narcissists - though by no means the majority - actually ENJOY abusing, taunting, tormenting, and freakishly controlling others ("gaslighting"). But most of them do these things absentmindedly, automatically, and, often, even without good reason.
What is unusual about the narcissist's sadistic behaviours - premeditated acts of tormenting others while enjoying their anguished reactions - is that they are goal orientated. "Pure" sadists have no goal in mind except the pursuit of pleasure - pain as an art form (remember the Marquis de Sade?). The narcissist, on the other hand, haunts and hunts his victims for a reason - he wants them to reflect his inner state. It is all part of a mechanism called "Projective Identification".
When the narcissist is angry, unhappy, disappointed, injured, or hurt - he feels unable to express his emotions sincerely and openly since to do so would be to admit his frailty, his neediness, and his weaknesses. He deplores his own humanity - his emotions, his vulnerability, his susceptibility, his gullibility, his inadequacies, and his failures. So, he makes use of other people to express his pain and his frustration, his pent up anger and his aggression. He achieves this by mentally torturing other people to the point of madness, by driving them to violence, by reducing them to scar tissue in search of outlet, closure, and, sometimes, revenge. He forces people to lose their own character traits - and adopt his own instead. In reaction to his constant and well-targeted abuse, they become abusive, vengeful, ruthless, lacking empathy, obsessed, and aggressive. They mirror him faithfully and thus relieve him of the need to express himself directly.
Having constructed this writhing hall of human mirrors, the narcissist withdraws. The goal achieved, he lets go. As opposed to the sadist, he is no in it, indefinitely, for the pleasure of it. He abuses and traumatizes, humiliates and abandons, discards and ignores, insults and provokes - only for the purpose of purging his inner demons. By possessing others, he purifies himself, cathartically, and exorcises his demented self.
This accomplished, he acts almost with remorse. An episode of extreme abuse is followed by an act of great care and by mellifluous apologies. The narcissistic pendulum swings between the extremes of torturing others and empathically soothing the resulting pain. This incongruous behaviour, these "sudden" shifts between sadism and altruism, abuse and "love", ignoring and caring, abandoning and clinging, viciousness and remorse, the harsh and the tender - are, perhaps, the most difficult to comprehend and to accept. These swings produce in people around the narcissist emotional insecurity, an eroded sense of self worth, fear, stress, and anxiety ("walking on eggshells"). Gradually, emotional paralysis ensues and they come to occupy the same emotional wasteland inhabited by the narcissist, his prisoners and hostages in more ways than one - and even when he is long out of their life
