There are three great destroyers of mankind, Plague, Famine, and Hero. Plague and Famine destroy your persons only, and leave your goods to your Heirs; but Hero, when he comes, takes life and goods together; his business and glory it is, to destroy man and the works of man.

Benjamin Franklin (1706-1790) American statesman, scientist, philosopher, aphorist

Franklin, referring to Louis XV and Louis XIV of France, uses the term "hero" her as one who leads their country into the "glory" of war and conquest.
