Answer:
This question requires a personal answer. I will give you my opinion so you can see how to formulate the answer and in case you think something different or want to add something else you can do it.
Explanation:
This question refers to the story The Sniper by Liam O'Flaherty.
I believe that the sniper is a victim of war, even though his actions may be considered heroic.
The fact that I believe that he is a victim and not a hero is the remorse he feels for having killed another sniper, just like him.
Although this person was the enemy, he did not have heroic pride in killing "the villain". Rather, he felt a great guilt for having killed another human being, someone who was a sniper just like him.
