Yes, that fits the profile of a sociopath - he manipulated you in order to get you off his back. The question wrt JFK is whether apologizing to her and his staffer was done out of a sense of guilt or was it just manipulation for his own gain. Unfortunately the article does not give us enough details to decide one way or the other.

Personally, I detest JFK and people like him, but I'm not sure if he was a sociopath. There's definitely enough evidence to make us wonder if he was, but probably not enough to get a definitive answer.

narcassists feel guilt. sociopaths cannot feel guilt.

something you wrote is wrong - you are contradicting yourself.

the wikipedia page on narcissists has no mention of sociopaths - http://en.wikipedia.org/wiki/Narcissistic_personality_disord... - while the page on sociopaths only mentions narcissists as a possible subtype or coexistence - http://en.wikipedia.org/wiki/Antisocial_personality_disorder

in short, when someone on the internet says contradictory things it's much more likely they are half-remembering something they read in a magazine five years ago than that they are a subject expert.

DSM-5 has been disbarred? Not that a book can be disbarred.

Mocked? Oh, wow. An online website of cultural criticism published an opinion piece on a medical classification and diagnostic tool. I guess we better throw it in the trash.
