The NPD constructs a false sense of self to counteract the heartbreaking treatment they received from their parent. In truth the NPD is a victim, but a dangerous one at that. It is unwise to show the NPD the pity and sympathy customarily doted to a victim, for the NPD will see this as weakness and exploit it duly.
The vacuum left by unbetrothed love in the NPD’s formative years is insatiable and unfillable. NPDs tend to be the offspring of other NPDs, or individuals with affective empathy disorders (of which there is a numerous and colourful range of diagnoses). Any love or sympathy the NPD receives as an adult serves merely as a form of ego validation, it is not sentimentally received or appreciated in the way the empath intended.
An NPD is a narcopath (a comorbid psychopathic grandiose narcissist), narcopaths do not feel empathy. A narcissist on the other hand merely has an elevated sense of self, a lack of humility if you will, but this alone does not signify an inability to sympathise. I refer to NPDs as narcopaths, for the absence of empathy customary to the NPD is tantamount to psychopathy, albeit, an egotistical variation on the phenomenon. All narcopaths are egotists, but not all psychopaths are egotists.
