There is a certain enthusiasm in liberty, that makes human nature rise above itself, in acts of bravery and heroism.
In the film world, we can all be heroes. In the real world, where heroism can cost you your life or the life of the ones you love, people aren't so willing to make those sacrifices. When they do, they are set apart from the rest of us.
I'm saying to be a hero is means you step across the line and are willing to make a sacrifice, so heroes always are making a sacrifice. Heroes always take a risk. Heroes always deviant. Heroes always doing something that most people don't and we want to change - I want to democratise heroism to say any of us can be a hero.
Extreme heroism springs from something that no scientific theory can fully explain; it's an illogical impulse that flies in the face of biology, psychology, actuarial statistics, and basic common sense.
Morality binds people into groups. It gives us tribalism, it gives us genocide, war, and politics. But it also gives us heroism, altruism, and sainthood.
