The reaction to the article "Without Emotion"

It's not hard to imagine what life would be during war time. He had to make himself brave enough in order to fight with the enemy also to kill them by his bare hands. Instead of being a chickedn in the war field, he chose to face it even he originally didn't want to be like that. War is cruel and unecessary, but as to gain the profits or dignity, people tend to win brucely in every battle. Leaders wanted to win but he himself didn't need to go on to war just like Bush Junior. The article is quite ironic or you can say sarcastic, the author wanted to reflex the brutal part of war, it's much more cruel than we thought. And it has huge negative impact on our pure mind, but also let us know the feeling to take one's life. It's like a dilemma in here, he's a man, he should be brave and patriotic, but he dare not to take someone's life if he had not practiced unwillingly.
