"Now who shall I kill next....." I mean... Memento

I thought the movie Memento was a very puzzling movie, and it made the viewer think a lot about the movie and about memory in general. I was not expecting much out of this movie at all, but i was pleasantly surprised by the presentation of the film and plot of the film. I thought the twist at the end was a very surprising and interesting twist at that same time. I would like to talk about his choice at the end of the movie. He chooses who is John G. and doesn't believe that there is only one John G. By choosing who John G. is, he then manipulated himself so he can figure out the puzzle and kill the man, knowing before hand that death of the man will be the final result. I think that is very interesting, because it can relay back into real life and out own choices. People choose to do certain things, which they may know will hurt them later on, but choose to do it anyways. Lenny knew that he was eventually going to kill the man, or at least try to, which if caught would be a very hurtful thing to him, especially with his memory condition. I think the aspect of choice was brought up subtly but in a good way as a side not to think about.
