Cannibalism is disgusting and “ethically questionable” at best. However the potential of having to deal with either your own temptations or the cannibalistic tendencies of the remnants of humanity is pretty much inevitable. Once the apocalypse strips away all our “normal” food sources, people will get desperate. Starving to death takes a long time so there will be plenty of time to talk your self into it. If you wait until you are put in that position to decide your stance on cannibalism you may make a mistake you will really, really regret. So it is of utmost importance to think it through carefully now, so when you are already reeling with post traumatic stress syndrome from what ever calamity wiped out society, you do not have to struggle with this complex ethical dilemma on an empty stomach…. (Grotesquely Continued)
First and foremost, you have to decide if there is anything more important to you then your own life. If not, then the decision is easy, cannibalism is for you. In fact, be careful not to wait too long before getting your hands dirty. Once things start to look hopeless, start with the fat people. A fat person can provide much more sustenance then someone who is just skin and bones. If you are all starving, that is going to mean less food the longer you wait. If your conscience still pricks you at this point, just tell yourself “I’m giving them a much more humane death then one of slow starvation (which, apparently, is one of the worst ways to go). Besides lots of cultures have practiced cannibalism for eons, not to mention other species, it is not pretty but it is natures way.”
However, if there are fates worse then death, and living with “cannibalism” on your life’s resume just does not seem worth it, then you have to ask your self if you are willing to see anyone you may be with die. For example your spouse, children, or that random stranger you fell in love with after they saved your life during the apocalypse and after you had lost everything and did not think you could go on they gave you hope, and in the following months you have shared everything and love each other deeply. If you are unwilling to watch a loved one die of starvation, then your two choices may be suicide and cannibalism. In these cases you could also draw the “I’m not going to kill anyone, but if they are already dead, then maybe” line.
Finally there is the (hopefully popular) opinion that there are some things worth dieing for, and even watching your loved ones die for, and among those things: under no circumstances will I eat or be complacent when others want to eat human flesh. Once you have reached this conclusion it is important for safety reasons not to fraternize with people who do not see things this way. They are cannibal time bombs, just waiting to go off. You do not have to preemptively kill them, however I would keep a safe distance from anyone I suspected of succumbing to cannibalism. Even if you meet them well after they succumbed, and it turns out they, “just did it, like once” and they “would never to do it again”, and they cry a whole bunch, if you let them stick around, you are taking a dangerous risk. You are just asking to pass through someone’s intestinal track before your remains can rest in peace.
