Narcissists live in a state of constant rage, repressed aggression, envy and hatred. They firmly believe that everyone is like them. As a result, they are paranoid, suspicious, scared and erratic. Frightening the narcissist is a powerful behaviour modification tool. If sufficiently deterred – the narcissist promptly disengages, gives up everything he fought for and sometimes make amends.
To act effectively, one has to identify the vulnerabilities and susceptibilities of the narcissist and strike repeated, escalating blows at them – until the narcissist lets go and vanishes.
Example: If a narcissist has a secret – one should use this to threaten him. One should drop cryptic hints that there are mysterious witnesses to the events and recently revealed evidence. The narcissist has a very vivid imagination. Let his imagination do the rest.
The narcissist may have been involved in tax evasion, in malpractice, in child abuse, in infidelity – there are so many possibilities, which offer a rich vein of attack. If done cleverly, non-committally, gradually, in an escalating manner – the narcissist crumbles, disengages and disappears. He lowers his profile thoroughly in the hope of avoiding hurt and pain.
