You just need to clearly state your answer yes or no to the question, before you list the points/examples explaining your viewpoint (I would delineate these examples clearly, introducing each point that defends your answer), and then close your essay by recapping it again on a conclusive note, perhaps elaborating on how he became an even better, more humane person for his decisions. So the reader can tell from reading your first and last sentence what your answer is, and each of the supporting points are clearly enumerated and not run together.

From your essay answer, it seems you would argue he not only escaped the trap of becoming a brute, but in fact grew in strength and character for having faced these challenges and consciously decided to act humanely and selflessly. You could say that his moral decision to choose those spiritual qualities of life over mere physical survival demonstrates that he purposely fought against the temptation to do as others did, and not only survived but came out a better person for it.
