Killing and destruction is just about the easiest thing to do in the world. Animals can do it. Creation is what makes us human. And no, creating a sharper stick doesn't count.
you are defining an out-group (those who wage war and violence) and creating a justification for potential violence against them. comparing them to animals.. it's obvious where that's going. this is what humans do. sharp sticks are a pretty great innovation whether you use them for skewering lamb or killing bad guys.
