Then one night, as I sulk around kicking stones, I am caught in a scuffle. A stranger, fully human, is about to attacked by a monster; the shadow lingers behind a great tree. The unsuspecting victim is, will be, taken, unless the monster is stopped. I have a bullet in my gun; I could save this person's dreams. The things which cross my mind in this moment are my own mortality, specifically the idea that I may be killed/mutilated if I cannot defend myself at a later date. Remember that I only have one bullet. The most moral thing to do would be to save the stranger, yes? I outstretch my hands with the gun wrapped in them, my finger hovering over the trigger. I squint in the semi-darkness, aiming for the heart of the shadow. But, hold on just a moment. Could not there be another instance like this in the future? What makes this stranger's life more valuable in my eyes than that of a future stranger? Are not the lives equal in theory? Two separate instances, they are completely the same, if we disregard time. However, there is that uncertainty, the uncertainty of whether or not a future stranger shall appear. My finger shifts shakily, firing the gun, killing the beast. The near-victim is startled, runs to thank me, offers me food. I am glad then that I did not save my move for a future moment which may never have arisen.
This forest is a life and death situation; the strangers that lurk are presences of your own mind. Do not hesitate to pull the trigger; do not wait to save the "right one." Do not wait for your time to come, or "they" will eliminate you.
