Silly question

Has anyone ever tried to confront someone with np that has np traits to show them they are acting like a narc? What were the results. I said before my narc is blaming depression and lifes events on his behaviour and asks i be pateint. Seems he is textbook case.. I gave him a book called dare to forgive. As he holds everyone accountable for everything. He cant forgive anyone. He didnt talk to his own mom for 11 years. HE rants to this day what she did..The x also ticked him off and hurt him. So i hoped he would dip into it anyway...then i thought man this guy doesnt wat to change..at all. His dr is even telling him that it isnt meds ..his lack of intimacy isnt due to the meds...he need excercise..if he even asked him about it.. Makes sense he did but...
Woyld they know deep down you were right? If you put trait by trait and give examples of what he did r how he has been acting? Someone told me narcs need supply..they knew of only one narc that changed and this narc used his need for supply to teach about narcism. He admitted and seen he had a problem. Is that most unusual?
