How does the sniper feel about war after he killed his enemy? Give reasons.

The sniper is filled with joy when he accomplishes his mission..... killing the enemy. Directly after, however, he is filled with remorse. In the end, we can infer that the sniper would like to see the war come to an amicable solution.

Then when the smoke cleared, he peered across and uttered a cry of joy. His enemy had been hit. He was reeling over the parapet in his death agony. He struggled to keep his feet, but he was slowly falling forward as if in a dream. The rifle fell from his grasp, hit the parapet, fell over, bounded off the pole of a barber's shop beneath and then clattered on the pavement.
Then the dying man on the roof crumpled up and fell forward. The body turned over and over in space and hit the ground with a dull thud. Then it lay still.
The sniper looked at his enemy falling and he shuddered. The lust of battle died in him. He became bitten by remorse.
