Hazing is a good thing, really.
It finds the mentally unstable in a controlled way, rather than allowing the nuts to cause greater harm in the wild.
Case in point: what would this guy have done after getting in the seat of an armed warplane?
The instructor should get a medal.
That’s a good point. Hazing is so common that it must have some kind of redeeming utility, and what you mentioned could easily be part of that.
He’ll get a note in his file instead.
