I’m not either for narcissistic behavior or ADHD being the cause.

I have several TBIs (traumatic brain induries) and I act like he does sometimes. Most of the time I can catch myself but everyone once in a while I’ll go into full “you’re all wrong, I’m right and stop hating on me” mode even when I am wrong. But I always admit I’m wrong afterwards.

It’s a maturity and, hate to say it, grace thing. Even when you mess up this bad, and then do it again, and then a third time, you have to step up and admit you made a mistake.

I have brain damage and I can do it. It’s just learning how to do it. Making that effort. I don’t think he knows how to do it or has never fucked up bad enough to want to learn how to admit to mistakes, or the reactions have never been negative enough for him to own up to it.

Either way - he messed up and should sit and think about it before doing anything else. He didn’t do that and it’s going to cost him. Maybe not a lot but something.
