Leonard... Lenny... Killer... or Victim?

In the end of the movie, I was really surprised to see that Leonard had been the reason for everything in the plot line. That he created this life for himself.

It was just truly unbelievable.

Firstly, I was in a really tough position because I'm not used to liking a character to hating him in such a short amount of time. His role as the protagonist to the antagonist was reversed so quickly!

And who was he really?

Was he killer?

Or was he simply the victim to his memory loss?

In the end, I came to the conclusion that to me, he was poor killer. Someone who you take pity on. He was a slave to his own hand. He made himself the killer. He turned himself into someone who wasn't him, with his own knowledge. That was so sad. Seeing how he created this labyrinth of life for himself was just pathetic and cold and sad.

And last of all, the whole end of the movie was just surprising. No one thought it would lead into him creating the facts himself. It was a beautiful thing to do - to create a tragically poor killer. Or an evil victim?
