How should one describe a person who is pathologically narcissistic?

Psychologist Joe Navarro offers this on Narcissists:

They all have or had an over-abundant belief that they were special, that they and they alone had the answers to problems, and that they had to be revered. They demanded perfect loyalty from followers, they overvalued themselves and devalued those around them, they were intolerant of criticism, and above all they did not like being questioned or challenged. And yet, in spite of these less than charming traits, they had no trouble attracting those who were willing to overlook these features.

These personality traits stand out as the first warning to those who would associate with them, but there are many others. Here is a collection of traits that I have collected over the years about cult leaders that give us hints as to their psychopathology. This list is not all-inclusive nor is it the final word on the subject; it is merely my personal collection based on my studies and interviews that I conducted in my previous career.

If you know of a cult leader who has many of these traits there is a high probability that they are hurting those around them emotionally, psychologically, physically, spiritually, or financially. And of course this does not take into account the hurt that their loved ones will also experience.
