Sam writes and speaks about psychopathy & narcissism. He’s the author of Malignant Self Love: Narcissism Revisited. He describes himself as a person devoid of empathy. “I do not possess empathy: I am a thrice-diagnosed psychopathic narcissist.” Narcissists and psychopaths lack empathy. This deficiency renders them emotionally and cognitively crippled. They exploit, manipulate, and abuse other people because they are unable to relate to them otherwise.
He says there are two type of empathy, one is ‘cold empathy’, it’s metaphorically like a library of books with no emotion. Psychopaths & Narcissists have this quality of empathy but do not see (or care) how their actions affect others.
