The thing with ptsd , and this is something I do know a little bit about , it can be treated but it’s commonly accepted it’s never completely cured more that you’re in recovery or it’s ‘in remission ‘ not that you can’t live a normal well adjusted life . What that does mean though is that it can come back triggered and compounded by other events . So if someone had it then finds themselves in a war zone it would be a real possibility it could reoccur but , and I’m aware that others will sneer at this , having your missus pilloried and insulted and the stuff they both lived through could easily cause issues .
I will say that when I had problems with PTSD I wasn’t a nice person to be around and mine manifested itself by overeacting to issues be they genuine or perceived . I have absolutely no idea if it’s an issue for him , like no clue , but If I was in Harry’s position when it was an problem for me and given an platform to respond to those I perceived as a threat or slighting me then the stuff he’s said would be nothing to the rubbish and vile you’d have seen from me .
Like I say I’ve no idea if it’s an issue for him and apologies for that boring soliloquy.
(Even writing what you’ve said Jimmy has made me reconsider certain opinions over some of his actions)
