Sometimes. Francois de Montmorency, count of Bouteville, was the champion dueler of France in the early 17th century. Before his execution at the age of 27 ( for dueling, natch ), in 1627, he was responsible for the deaths of 22 men in duels. This isn’t even including his own seconds who died fighting by his side ( the count there was more than one, though I’m not sure how many ). He is the perfect example of the worse case scenario in dueling - a superbly skilled, arrogant young asshole who baited people into death matches and caused a never-ending cycle of blood-feuds that engendered fresh duels and deaths. Louis XIII made an example of him for good reason.
