What change becomes apparent in the sniper after he succeeds in killing his opponent? How do you explain this change?

When the sniper kills his opponent, an important change comes over him. All of a sudden, he loses the "lust of battle," for example, and he feels "revolted" by the sight of the dead sniper. This contrasts sharply with the sniper's appearance and character before the killing, when his eyes were like those of a "fanatic" and he was described as being "used to looking at death."

When the sniper kills his opponent, an important change comes over him. All of a sudden, he loses the "lust of battle," for example, and he feels "revolted" by the sight of the dead sniper. This contrasts sharply with the sniper's appearance and character before the killing, when his eyes were like those of a "fanatic" and he was described as being "used to looking at death."

By creating this change, the author makes an important point about killing. Specifically, that there is no glory in causing the death of another person, no matter what the circumstances or context.

Even though the sniper has killed before, he is clearly affected by the death of his opponent. This suggests that death leaves an emotional scar on the killer, no matter how many times he has done it in the past. This is significant because it draws the reader's attention to the human cost of war, made all the more poignant in the closing line when the sniper learns that he has, in fact, killed his own brother.
