What risk does the sniper decide to take after killing the enemy?

The sniper decides to take the risk of ascertaining the identity of the enemy sniper.

When the sniper reached the laneway on the street level, he felt a sudden curiosity as to the identity of the enemy sniper whom he had killed. He decided that he was a good shot, whoever he was. He wondered did he know him. Perhaps he had been in his own company before the split in the army. He decided to risk going over to have a look at him. He peered around the corner into O'Connell Street.
