As human beings, we all have reasons for our behavior. There may be people who have certain physiological issues that dictate why they make certain choices. On the whole, though, I think we're dictated by our structure, our past, our environment, our culture. So once you understand the patterns that shape a person, how can you not find sympathy?

I think that cinema and the arts are central in our lives because we grow up and learn about the world through our exposure to stories. Parents use them as a tool to teach their children fundamental truths and values, much as adults can view them to gain exposure to cultures and individuals that they'd never be able to view in their own lives.

In some sense, when you take a child soldier out of an armed group, you've taken away the identity he or she has had for years, and you can't assume life is just going to return to normal.

I put down the camera long ago, you know? I was here in London, aged 19, and I was obsessed with my camera, shooting everything I could. Then someone stole it. It helped me to see things for the first time.

You try to pull away the experiences until you get to the core of humanity, and you find that light that exists in everybody. It's that light that I'm searching for in all of my work - is that connective thing, that ether that enters all of us - you know what I mean? That's a part of God.

For many child soldiers, war and violence are all they have ever known. If we don't take it upon ourselves to show them an alternative, then they're going to be soldiers forever, and they'll continue to be recruited and to participate in violence if another conflict starts five or 10 years down the road.
