That's interesting, because for me personally, it's definitely better understanding the actions of narcissistic disorders as being the result of variances of the human psyche that has made it easier for me to distance myself from emotional tie-ins with the NPD's (and other Cluster Bs) in my family and thus bettered my opportunity for personal sanity. When I did still look at their actions as primarily being choice-driven, my emotionality over it was only fueled in an unfortunate way.

I'd so much rather support healthy emotional distances through identifying the differences between us in a clinical way (and, of course, not giving anyone enough rope to hang anyone anymore) than by having those distances be the result of what anyone did or chose. The B cluster is just not a place I've found to be beneficial for the investment of any intense emotional energy, positive or negative.
