Harry may have suffered enormous trauma with the tragic death of his mum, and the fact that the royal family is a bit odd with regards to the touchy feely, but he has also had immense privilege and the opportunity to do anything he wanted to. There is freedom in being the spare. You still get all the privilege, but you don’t carry the weight of being the monarch.
Does Harry wish that his brother had rebelled? William is doing the familial duty, of behaving appropriately as a heir apparent. I am not sure how Harry expects William to be? He has be in training all his life, he is shackled to duty and just getting on with it. Can you imagine if William decided he wanted out, he would walk away, disappear and lead an entirely private life. Not this carry on.
Harry has wasted the opportunities he has been given. He could have gone anywhere, done anything - but he has chosen the life of a perpetual victim and loser. What an utter waste of time and energy. What is the point of rehashing everything? Will it make him the heir? Will it make Meghan the Queen? Will it bring his mother back?
William is pragmatic. I think he was a crutch for Diana, which was not a great maternal move on her part. I have no doubt he loved his mother very much but he probably realised that life is not black or white, it’s nuanced, and there is no use hating Camilla or his father, that sometimes circumstances collude to bring bad outcomes that might not necessarily be perfect, and that people are human and get stuff wrong some of the time, but what’s the point of hating everything all the time.
Harry has lost the public now I think. Those people who are still dogmatically defending him do so out of ego, they don’t want to admit they were wrong. Lots of people face cruelty, tragedy, poverty everyday - most people have no option but to keep things moving. He has the luxury of wallowing in it, and boy is he good at it.
