“To be successful, the guerrilla must be loved and admired. To attract followers, he must represent not merely success, but absolute virtue, so that his enemy will represent absolute evil. If the soldiers are idle, drunken or licentious, the guerrilla must be vigorous, sober, and moral. If enemies are to be disposed of, it must be for moral reasons: They must be traitors, murderers, rapists. The revolution must show that its justice is sure and swift. By contrast, its enemies must be revealed as venal, weak and vacillating.”
