Wars do not only claim many lives but also spoil/destroy a man's character. Do you agree with this statement?

I do not believe that being in war spoils a man's character. War, it is an event where a country conquers another country because of many reasons, maybe it's for power an expansion for alliances to others. But for the situation for the Trojan war is different. It is about a girl named Helen that brought the war to Troy. I do not believe that war spoils a man's character because the man is doing war not for himself but for his country. I wouldn't call it a spoil but I could maybe compare it to Sacrifice which I think is different from because Sacrifice for me doesn't destroy a man's character but instead it builds him up. The soldier's actually stand for something when they're going to war, they go to war for the betterment of their country. A man killing people for no reason is very different from a man killing for something good or for the better. Yes, war does claim many lives and some other soldiers feel that they are weak after a fight, weak in spirit I don't know, maybe they feel that way. The regret that they killed a man, and other reasons that made them less of a soldier. But a real soldier must think after the war is that they must feel honored and they must feel the victory! They must feel that they have succeeded in protecting their country and that they succeeded in protecting their people. Truly, I don't think that killing a man in war doesn't spoil a man's character because war is supposed to be for something. War is somewhat a good thing because war is sometimes the reason that there is unity in a country. War does not spoil a man's character but it builds and show a man's character. That's what I think and that's what I also feel about war.
