A Narc's Motive

When we first meet them and they go through the honeymoon stages of the relationship are they truly planning and setting out to not mean it, as in, faking their feelings initially? I have read the book and others that I have found and they do say that these disordered people are incapable of normal feelings because of their brain disorder..ok so they can't feel normal feelings but when they met us they did like us and for all we know they loved us in a way that they THOUGHT was how love feels, right? What has been really heavy on my mind lately is how we are all so angry *I am referring to those of us who are broken up or have been for quite some time and still carry the anger with us* when we know that they are incapable of normal thought/feelings. Take me for example, I am angry but not bitter but angry YES and yesterday I was embracing my feelings of anger and having a huge pity party and an I wish I could get revenge frame of mind, but then I thought wait...maybe he did not do this with hatred and malice in his heart since he can't feel anything anyway? So why am I angry? It was sort of a light bulb moment, asking "Why am I angry and feeling insecure about myself when this man is not a normally functioning human being?"

Do I get angry that a blind man can't see or a deaf man can't hear?

Has anyone ever looked at the personality disorder in this way or do you all think I am crazy? lol
