As a firefighter/EMT I occasionally have to deal with death, and I will even put myself in somewhat dangerous situations (that I've been trained for, and for which I have appropriate PPE) if there's a chance I can save a life.
But putting myself in a situation where the likelihood of dying is quite high for no reason other than to say I did it? No thanks.
Nevertheless I'm glad the family of Mr. Morup is no longer wondering what happened to him.
I mean you do firefighting because you like something about it, maybe the feeling of doing something good. So it should be understandable doing something dangerous for some good internal feeling. Your driving feel good feeling is just different from theirs. The fact you dismissed it to just be "to say they did it" doesn't mean that's how they feel about it. There's ways to be dismissive about being a firefighter too, but they aren't fair.
I do do some things just to say I did them. Or to compete with myself so I can push farther. But for the most part those things have much lower risk of death than climbing Everest. And it's easy for my family to retrieve my body in the unlikely event that I die.
If I ever climbed Everest it would only be to recover some of the bodies or preferably bring down somebody still alive who needs medical attention. I would not consider it "fun" but that's just me.
This subthread isn't about what is most valuable to the world. It is about what makes someone take risks. One guy's superficial need for adrenaline might still represent a much bigger internal feeling of "I have to do it" than another guys internal feeling of "I like to help others so I do this". Because the firefighter only understands taking risks to do something moral doesn't mean others operate the same way.
