You can kill anyone with any physical object. There is a way to do it, no matter what the object is. Gunpowder based weapons were originally invented to be used in war. In fact, dozens, if not hundreds of everyday objects we use today were originally invented to use in war or for killing purposes. Pretty much all the technology we use today, like the internet... was originally invented to implement into weapons systems. Warfare is inevitable between humans, so weapons will always be made, no matter what, even in peacetime. Guns are merely an easier way to kill people from a distance and ensure a nice clean, almost instant death or at least severe injury. There are much more effective ways of dispatching people, though.
