His private life would be his private life ... except it wasn't ever kept private - he wrote books about his life, he solicited donations based on his life, including the notion that he was a devoted family man and caring husband which we now know was a complete veneer or lies.
The reality was that he'd been treating his wife like shit for at least the last half-decade, probably a lot longer (I don't think people really change who they are, and it seems like he's always been a sex-pest all his life, as documented by his own accounts).
He decided to live his life in public and make money from doing it, so his "private life" was never private and is fair game for commentary and critique.
Lloyd - it's your personal life, not a private one, and you didn't keep it private so why should anyone else bother to?
You made your own bed, lie in it you sick mother fucker.
