Thirdly, people sometimes include rage within the meaning of the term courage.

Those who in sheer rage turn like wild beasts on those who have wounded them are taken for courageous, because the courageous man also is full of rage; for rage is above all things eager to rush on danger; so we find in Homer, “Put might into his rage,” and “roused his wrath and rage,” and “fierce wrath breathed through his nostrils,” and “his blood boiled.” For all these expressions seem to signify the awakening and the bursting out of rage.
