Campanologist - you might find the modern military take a dim view of what is essentially flying indiscipline too
I have recently attended a mil-run flight safety course as a refresher and had the Catterick Puma crash dissected at great length including listening to the CVR tape - it makes one's blood run cold.
This guy, at worst, needs a gentle re-education about levels of acceptable behaviour, he may work at a place where this is the norm and they have slipped into a poor culture.
As a reminder, the OP started off with this as a jackstall (servo transparency) issue and much of the outrage was directed at how much damage he had done to the aircraft etc I think we have put that idea to bed now and it is just the choice to fly that manoeuvre that is at question.
