I feel sorry for him because he does not seem to realise the impact his words will have on him and his own nuclear family.
Perhaps we should step back a little and consider how we would feel if we had a grandson like Harry.
I believe he's immature, self-obsessed / absorbed, and doesn't have the intellectual capacity for genuine self-reflection.
I also think he - like his father - has not had a normal upbringing. How could he in that rarefied, royal, aristocratic environment. I still remember that photo of his father, Charles, as a 4-year old (or about that age) shaking hands with his mother after a long absence when she and Philip had been on tour for many months. For all the attempts of various pundits to promote various members of the RF from time to time as being "just like us normal people", they are not.
For a while, he was the darling of the media - our 'Jack-The-Lad' Prince. And then the media did what it does best - chronicled gleefully the inevitable downfall of their icon - because they know a large section of the public is focused on the royal family. And Harry, not having the critical ability to fully understand the media dynamics, their modus operandi, and not being astute enough to simply keep a dignified silence, gave the media the meat and drink for them to demonise him. Instead of thinking long and hard before embarking on his exposé, he went full tilt.
If he were my grandson, I'd want him to get help - the help of someone disinterested and completely impartial. I think it's all very sad, and rather depressing. However, I'm not invested emotionally in the royal family, I don't feel insulted on their behalf. I don't believe he'll 'bring down' the 'firm' or cause any major disruption to the institution of monarchy either - as the media hint and some believe. Harry is authoring his own downfall, but let's not pretend the media are not enjoying it, and milking, it for all it's worth and, in so doing, are perpetuating it. Harry is, I'm sure, aware of this, but does not have the emotional or mental capacity to deal with it effectively. He needs a friend, an honest friend - a guru / a counsellor... someone who cares enough about him to guide him. I am, of course, looking at him through the eyes of a grandmother who sees the folly of his actions but can only stand back and watch him fall further into the trap. I feel sorry for him.
