Less dying for and more killing for really. I mean if you are killing the best officer in the US Navy over wounded pride are you doing the right thing? Is it worth setting back your country's Navy by years or decades because it lost such an excellent leader? Is that harm to millions including possibly losing you a war worth one man's pride?
That's the big example, but Handel almost died in a duel, if he had the world would never have had some of the finest music ever written. France lost one of its best mathematicians, a man who as a teen solved a 350 year old puzzle but was dead at 20. Killed over a harlot.
Russia lost its best Poet to a duel, but then you also have Tolstoy. Not the writer Tolstoy but one of his relations, a man who cheated at cards, duelled those who caught him, killed them, and went right back to cheating.
He killed upwards of eleven men to the point where he didn't duel for honour but because he was bored. You can't refuse his challenge, but he's only giving it because he has a slow weekend. Is that worth dying for?
