I'm not sure if I've done something like that purely out of the benefit of someone else, like looking out for future generations.
I know there was a couple of times where I've withstood a tyrannical manager in a cutthroat business. She had called me "weakling" and things like that because she didn't like how I wasn't aggressive towards others. There were a couple of times, she would zero in on me and in my business to try and make an example of me. I guess she thought that I was the weaker link, though my sales were above average. Idk.
When it came down to it, even with her threatening to fire me, I would not be cowed by her. I am not a dog or a cry baby. If I lost my job, it will be with my dignity intact and not with my tail between my legs.
