You are right, Arneb. That is why I said I was not criticizing you. Just one of those things that punches my buttons. :(
To me, the gallows humour in "famous last words" is in the irony, that the person speaking should have known better or took a stupid chance.
In the case of the Challenger, the stupid chance was taken by the NASA administrators who, despite urgent warnings, threw the dice with the lives of the crew. The crew lost.
If the administrators had died instead, then those "last words" might be funnier.
"He who fights with monsters might take care lest he thereby become a monster. And if you gaze for long into an abyss, the abyss gazes also into you."
