Joseph Campbell said this quote

“ The battlefield is symbolic of the field of life, where every creature lives on the death of another. A realization of the inevitable guilt of life may so sicken the heart, that like Hamlet, or like Arjuna, one may refuse to go on with it. On the other hand, like most of the rest of us, one may invent a false finally unjustified image of oneself as an exceptional phenomenon in the world--not guilty as others are, but justified in one's inevitable sinning, because one represents the good. Such self-righteousness leads to a misunderstanding, not only of oneself, but of the nature of both Man and the Cosmos. The goal of the myth is to dispel the need for such life-ignorance by affecting a reconciliation of the individual consciousness with the universal will, and this is affected through a realization of the true relationship of the passing phenomena of time to the imperishable life that lives and dies in all. ”
