Lol! Why? If you're making this choice because you assume that Gunpowder is the reason for many murders, suicides and wars, what about gunpowder saving your life! Isn't it something that is more capable of self defense than swords and arrows! Also, swords and arrows were killing more people in the past than Gunpowder is killing these days. So, If you choose gunpowder only on account of looking at the negative side of it, please look into the positive effects of gunpowder as well!
