I will always pray that I will never be in that situation. Never.
With the question of the actions of Dudley, I would definitely say that ideally it is wrong. Eating one of our own is one of the oldest taboo in human history along with the case of incest. But definitely, this act is not new to us; take for example the existence of the cannibals. Ideally and with all the moral related issue that we have learned from the society– this is an act that is not acceptable. But definitely, there is another side in this story. The issue of the survival of the fittest and the like– and the practicality of what to do in this situation. In my own honest opinion, it is not acceptable to kill the young Richard Parker because he has no wife and children and because he was weak. They should have done a draw lots for equality.
If I will be in that situation, I will definitely try my best not to resort into eating human flesh. Even though according to some that we are the most clean and definitely the most delicious meat in this world, eating one of our own is not just me. Maybe, I’ll starve myself to death. Maybe. I will never know and I don’t want to know.
