It's certainly true that the system is broken, but at the same time you're suggesting we should forgive HR employees for the bad stuff they do, and I don't think that's how morality works.

Not only that, we all understand that sometimes employees don't have control of a situation and they're going to follow company policy or go along with their bosses. But we can see through their words and their body language how they feel about it, and we can recognize small actions that they could take to make a bad situation slightly less bad. In my experience it's very rare that you will encounter such behavior in HR, because the vast majority of HR workers are perfectly happy to f*** us over as much as they can.
