To make a point by way of extreme -
Not so long in our society someone who committed acts of say, random torture, might have been thought of as being possessed by demons. Such a person might have not felt bad at all, even enjoyed torturing, but the lack of being bothered doesn't mean that the rest of society feels there is nothing wrong. In the last century such a person might be labeled a psychopath, a sociopath, as having anti-social personality disorder, and in the future, who knows what labels.
In the end though labels only matter so much. That the person who others label as having x, y, z problem is how others really feel. The person others label as having a problem may not feel anything is wrong with them, but then, is that so surprising? You know if we were all wolves, aggressively fighting over scraps of food might be considered the norm, and polite sharing might get us labeled as flawed. So to a degree what is normal is relative, still...
If some guy walked up to you and said "I want to torture and kill you, keeping in mind I don't feel there is anything wrong with me", my hunch is you'd disagree. An extreme, but the point is it's often not the 'disordered' person who feels the negative effects of their thinking so much as it is others.
With HPD the issues are murkier. Take the context of someone single, maybe younger, is there anything wrong with going out, being the life of the party, being flirtatious, being charming, etc? Not really. Most of us wouldn't give it a second thought. Then again, extreme example, but, we probably wouldn't give it much thought if a soldier dressed up in combat gear in the middle of a war and started shooting strangers. In that context, it's normal. If he did the same thing during peace time and shot 'friends' though???
Personality disorders are about extremes of behavior, that affect others negatively (they don't necessarily cause the disordered any personal harm or discomfort), that are problematic because of their frequency, severity, and occur in contexts that cause others discomfort or harm.
