war...the value of life

I don’t think i can ever fight a war. war...war a horrible thing…completely useless, no one won the last war, and no ones gunna win the next one, its pointless, nobody wins in war, everybody just loses. so then why do people do it. does the ends justify the means? I think not, I think all life is equally valuable, to kill one to save millions to me doesn’t make sense, there are no guarantee that that one would live to be a million or that million only live but one day. even if that life does nothing but just live without harming others, maybe its not a great epic love story, or the next world leader, what makes one life more or less valuable than the other
