The path of action is an uphill struggle and only those who are both honest and strong are up to the task of facing its extremes. The warrior vocation involves resisting evil in such a way that only a minimum of violence is manifest in order to adequately defend the truth. The will to righteousness is never lost, the warrior never becomes a cynic, but remains a realist who understands that his childhood dreams of fighting through the bog and coming out clean on the other side are just storybook fantasies that can be excused in children but must be condemned in adults. “Being a saint in a dream is not the same as being a saint in practice.”
We could say that the warrior must possess a vision of purity and righteousness and that his will must be upright and oriented toward this vision, but that the path of action he must tread does not perfectly reconcile with that which he loves, and in a sense he must go where he does not wish to be and suffer loss, all out of a desire for the good, or to say it another way, for the love of God.
To kill the villain is an evil, but it is a lesser evil than to let him butcher the innocent; the warrior carries out the evil that is the execution of the villain, and takes upon himself the stain of that evil, and not out of some delusion that in doing so he remains pure. Rather, he permits himself to be debased out of love for God and for the innocent he defends and because it is the only way.
The warrior never desires evil, which in a way implies that he never really wishes to kill, or would certainly choose another way if it were possible. He kills because he loves the good and because it must be done in order to protect the good and because he is in a position to accomplish this feat. He accepts the sacrifice, and he suffers the loss. This is the true nobility of the warrior, that he imitates Christ not in his purity but in his suffering. The warrior takes upon himself the sin of human conflict.
