I think personality is personality and it's more about the "style" versus the "disorder". I think how one "uses" one's personality, how one displays it, acts on it, expresses it is what makes the difference. Everyone gets angry but there's a "good" way to express it and a harmful to self/others way to express it. I think personality is like that, learning what one's person is like and what one enjoys/one's "style" and then how to express it so it expresses one's self and doesn't hurt one's self or others.
