Above all else, the barber did not want to commit the greatest sin of his profession--to spill a drop of the customer's blood. Killing Captain Torres while performing his barbering duties went against the unwritteen barber's code. Additionally, the barber considered it a cowardly act of murder, killing the captain while his eyes were closed. He believed that killing the captain in this manner would make him no better than his victim. Also, the barber knew that he would be identified as the killer--murderer or hero, he knew not which--and he had nowhere to go to hide from the men who would be hunting for him. Killing the captain would also reveal his true identity as a spy for the rebels, and by blowing his cover, he would no longer be useful as an operative.
