Interestingly, it wasn't until World War I that your sentiments started to reflect the majority view. While today nearly everyone feels as you do throughout human history until only a century ago the vast majority of civilizations glorified war. For the Vikings to die safe and warm in one's bed was the worst kind of death imagineable; it completely lacked glory. In Aztec society one could not progress in status without engaging in warfare. Warrior was a respected title.

Ever stopped to think about why evolution has turned the human male into a creature significantly bigger than the female? Why all that upper body strength? We've been bred to be warlike and tough. Sports are simply avenues to release the natural tension in the male that used to be released through violence. War has been a fundamental part of human society since the beginning and most of the earliest history of humans deals with warfare.

We're all going to die at some point in our lives (normally at the end!). Yes, war is terrible and involves a hell of a lot of suffering. But all that risk and pain is what made the victories so glorious to past peoples. There is very little glory or true excitement in the modern world. Everything is just titilation. We only see war in movies and the war movies we see today are entirely seeped in the anti-war sentiment so prevalently today. War isn't always the unremited hell that is portrayed in modern movies. It certainly wasn't the wonderful past time that ancient people's portrayed it but don't fool yourself into believing completely the modern tales about warfare.
