Book Three - Moral Laws
Chapter VI - V. Law of Destruction
758. Can dueling be considered murder on the part of the individual who, knowing his own weakness, is realistically sure of being killed?
“That would be suicide.”
a) When the chances are equal, is it murder or suicide?
“It is both.”
In all cases, even when the chances are equal, duelists are guilty. In the first case, they are guilty because they make a levelheaded and deliberate attack on the life of a fellow human being. In the second, they risk their own lives for no reason and without serving any benefit to anyone.
