It would be better if there wasn't a war in the first place.
I. HATE. WAR.
War kills people, innocent people, and if they survive they're tormented mentally.
Taking someone's life because of a fight your leader began or went through is just cruel.
Unless it's for self-defense, which in that case isn't war but well, self-defense.
War will never be justified.
And the ones who started them should burn in the fires of You-Know-Where.
