When people have the freedom to choose, they choose wrong.
That statement is so true. With freedom and choice, humans eventually choose wrong. Not every time, not even most of the time, but enough times to make those wrong decisions significant.
In America, we're lucky enough to have freedom. But freedom comes with a price. The price includes everything from 9-11 to the Boston marathon bombing, school shootings, rape and murder, child and domestic abuse, theft, embezzlement, lying, cheating, stealing. Nobody wants Big Brother governments or dictatorships, even if it comes with less crime and more peaceful societies.
These dystopian type movies are basically telling us that above everything, freedom is the single most important thing for humans.
