I constantly think about this film. The amount of moments that must have been lost to time. Vague memories that must me merged into innate feelings and instinct that shape John into the person that he is. Does he actually learn from his experiences, and chooses to be the man that he is? Or did his experiences literally whittle him down to the person that he has become. In essence: Is he the embodiment of a mankind that witnesses the consequences of its actions, or is he the very antithesis of it (telling in the way that he distinguishes himself from others, whilst being extremely humane in every interaction). On a lighter note: I also wonder if he can juggle and do a backflip, or if he could and these skills were lost to time. In the same way that many of us are defined by a childhood that we barely remember, I wonder if his generosity and kindness is born from a blur of unconscious experiences he barely remembers.
