I found the comments Harry made to Oprah interesting for a couple of reasons. Firstly because of his background, and the “'I was always the yes man I was always the one willing to say yes” comments. This is the same man who spent many years in the Army, where the whole culture is supporting the organisation’s aims and saying yes to everything you are asked (ordered!) to do. It’s impossible to overstate how much that culture in embedded within the people who thrive in that setting. I’m not saying this to knock his response to the situation, obviously soldiers get burned out too, but to an onlooker it’s seems its unlikely to be just the time spent as a working royal that led to his burnout - he’d had to be a “yes man” for years and years by then.
And secondly, the Royal family weren’t themselves saying someone needs to go to Nepal. Foreign travel by the royal family (other than for holidays, obviously) is determined by the Foreign Office, and planned in accordance with their wishes, needs and priorities. The FO will have said to the family that they would like someone to go to Nepal, and the Royal family’s job is to fulfill that request. And so they obviously asked Harry to attend. So he wasn’t doing his family a favour, he was fulfilling the obligations of his family to the government. I think that gets totally lost in his account.
Harry is of course under no obligation to present his feelings in a nuanced way, or to give a wider perspective on his situation. But it does seems he has come to regard them as the fault of his family alone. This does also come into the rewriting history that he’s doing.
