Pretty much all the Kennedys, as far as I can see. Joe Kennedy, Sr., was a mobster, and over the years it seems to have run in the family. For several generations.
Drunken, womanizing, “I’m entitled” louts, just about all of them. JFK’s mother seems to have been a decent woman, and she managed to teach the brothers some manners, if not actually improve their behavior. So with the complicity of the media they got away with it.
Considering what she allowed Joe Sr. to do to her namesake, I gotta disagree. IMO, Eunice has made a career of doing penance for her parents' treatment of her sister.
...one seriously messed up family with enough ill gotten money to do as they damned well see fit.
