The thing is, Jag, as Chaltab points out, people join the army and go to war to defend their nation, to defend innocent people. That doesn't mean they want to kill. And while you're right that, if everyone decided that violence wasn't necessary, then war could be averted, there will always be someone who solves their problems with violence. If someone starts the violence, you're already in a defensive position.

Nobody "deserves" to die. But violence is a part of human nature. A part of our heritage. A part of our culture. You're a little misgiven if you think you can convince everyone to stop fighting by saying "Violence is wrong, guys, see?"
