The ending is kind of silly. I'm sure in a couple of decades, or generations, if you like that better, everyone who partook in this little incident would be dead, and the hatred of lulu would slowly fade into the history books. This is when the events of the past will begin to replay themselves; greed, crime, warfare, and whatever you might fancy to be bad will return. That's how I imagine things would work out, lol.
Human history is the story of complaisance. While disaster is fresh in our memory, we take precautions. But as the memory of disaster recedes, we start to take risks.
