>That’s grounds for termination to me. Seriously. I would put this man out of a job and endanger the livelihood of him and his family for this kind of shit.

Agreeing with you as a former instructor (who left academia for greener fields after completing the PhD).

I've had people cry on me in office hours because they come out with — quite literally — PTSD from instructors like the one we're discussing.

It's nothing short of psychological abuse of children, and it leaves lifelong damage.

It's worse than no instruction at all. I've had to have college kids unlearn things before I could teach them.

We've got to draw a line somewhere. I draw the line at actively traumatizing children.

That person should not be allowed to teach, period. We'd do both their students as well as themselves a huge favor by removing them from teaching.

By all indications, they'd be a happier person doing something else, where they wouldn't be driven "mad" by seeing that they've done a good job — which, for a teacher, means their students being proficient in the subject they teach.

TL;DR: this teacher was driven "mad" by seeing that he's done a good job, and one of his students was really good in the subject.

Spare them from this pain.
