War

Living in this day and age, you come in contact with a lot of war-talk. Not to mention all the historic wars you learn about in school.
My view on war is that it may not be right, but it is inevitable. Humans, by nature, will disagree. We will kill each other. It must happen. Most of us consider killing one of our own kind a horrible deed, yet it happens all the time. We look upon animals killing each other as some kind of awful thing, but we, if left to our instincts, would likely do the same. True, I do not think it is right to stamp out another person's life. That is exactly what war is based on, though - we do something to others that is not right to them. If killing were not considered so horrible, it would not happen in war. If we considered sneezing on another person awful, war would be a bunch of people sneezing on each other. It sounds laughable, but it's true.
