I think Harry is being very unfair to his father and the RF about their parenting.
I'm closer to Charles' age not Harry's and can remember a lot which other posters here are maybe too young to know of.
Charles and Diana tried hard to break the pattern of parenting which they'd had.
Charles did not pack his sons off to Gordonstoun. They went to school near home. They took them on royal tours, even as babies, compared to the Queen who left her children with nannies for months. They exposed them to people in need, visiting the homeless for example.
None of us can choose our parents and all of us carry the baggage of our own upbringing. [Hello Philip Larkin's poem.]
Harry's downfall is he never really had a role in life and he never got over his mother's death or stopped blaming others for it.
He wasn't academic, he was always going to be 'the spare to the heir' for a while, but he had the time, means and money to be a playboy. That's a bad combination. If he had stayed in the RAF it may have worked for him because it gave him a purpose, structure and a 'family'.
He had the chance to have a nice life- a minimum of royal duties, where he would promote MH, help the Heroes, Invicta Games, and also enjoying the vast wealth that came with being royal.
The public liked him as the more interesting 'naughty' son.
But when he met M, it seemed to fuel his unhappiness and make him focus on what wasn't to his liking, rather than making the best of what he could have.
If he wanted to leave and be out of the limelight, fine.
But to ask for privacy, detest the media, and yet sell his soul via US TV- no, that's not bravery, it's stupidity.
