Human beings live in a constant state of war and though for the most part this war is spiritual and not physical in nature, it is still a war nonetheless. It is known as the war within. This is one example of perpetual war. At first glance it may seem a bit cruel and unusual but because we have been granted what we like to call "free will" by our creator which allows us to choose the right path or the wrong path, this is actually considered pretty normal for us. Chaos and insanity only occurs when this internal war is trumped by a continuous state of war in the physical realm which it seems we are currently experiencing. When there is absolutely no escape and the line between both worlds has become completely blurred creating a constant state of madness, it is then that you shall surely know that we have entered the gates of hell.
