"under certain circumstances violence-acting without argument or speech and without counting the consequences-is the only way to set the scales of justice right again. (Billy Budd is the classical example.) In this sense, rage and the violence that sometimes-not always-goes with it belong among the "natural" human emotions, and to cure man of them would mean nothing less than to dehumanize or emasculate him. That such acts, in which men take the law into their own hands for justice's sake, are in conflict with the constitutions of civilized communities is undeniable; but their antipolitical character, so manifest in Melville's great story, does not mean that they are inhuman or "merely" emotional."
