Thinking about a war after reading Jojo's Story

<<注意>>ねたばれの恐れあり
"Jojo's Story"の最初の方の引用が少しあります。最初の方なので筋を予測できるような部分ではありません。
また、南京大虐殺に関連する記述があります。残虐なシーンの嫌な方は読まないほうがいいかもしれません。

I just finished reading "Jojo's Story" ofCER2.
It's a story of war.
The　story begin the scene that a small country village is emptied by soldiers.
It say, "they are dead. My mother, my father, my sister, my brother. My family. ・・・My mother had no clothes on. I've never seen my mother without clothes.・・My sister's dead on the floor. There was blood on her leg. I pull down her skirt."

When I read these sentences, I remembered the story that I heard at last summer.
I heard this on a TV. One old man, about 80, told his story on the world war 2 without face.
He was a soldier of Japan army, And had been fought against foreign countries at China. The war last long time. The soldiers were very tired. Also they were very hungry at food and women. Then lower level soldiers sometimes attacked small villages for those. He said, "One day, we attacked one house at small village. There were one old father and mother and young daughter. We started taking off the daughter's clothes as usual. The father of her asked us let go her with tears and bowed on ground. But we ignored him and had raped his daughter. After we finished we killed them. Because we were afraid they talk to our boss about this." He also said, "Almost soldiers were doing same without reasons. We should be crazy. But no way at those time." At last he said that he never tell this fact to his family. But also he felt he must tell this others for records.

Is this a old story? NO! The same things are going on at somewhere in the world. I read it on Newsweek at last autumn that the same things had been happened at Chechen(sorry I'm not sure the name of place yet) by Russian soldiers. And maybe now somewhere.

Dose wars make them bad? And are these soldiers bad?
I'm not sure. But I'm sure that a war is bad.
And we must see this fact or ignore this?
