In my former line of work, as a wildland firefighter, an individual who endangered themselves, endangered their fellow crewmembers. It is also my experience that one who so wilfully (and dare I say pridefully) flaunts safety rules, is probably more fo hazard than they they think. I'll reiterate that I am glad that I never had to work with you.
Certainly no one has ever been injured or killed trying to save a person who was "only endangering himself."
