Answer:
D. The corruption of the good by the forces of evil and selfishness
Step-by-step explanation:
War is always, and should always, be talked about in a negative connotation. In this case, the "forces of evil" is the negative experiences that the officer has obtained, whether it was the death of close comerades, or the experiences of first-hand killing of enemies. When one has seen the negatives of life in the underworld of war, the old age beliefs of honor within a battlefield is but lost. As such, when the virginity of a person's innocence is destroyed by the harrowing experiences, and, most likely, the close view of death, they lose interest of the every-day blessings, such as that they cannot get over the nightmares (PTSD). When the goodness of the world has been removed, and one is only exposed to the worse, the viewpoints of one become narcisistic, and the joys of life loses it's color and prestige within one's life.
