dark knight

Alfred Pennyworth: When I was in Burma, a long time ago, my friends and I were working for the local Government. They were trying to buy the loyalty of tribal leaders, bribing them with precious stones. But their caravans were being raided in a forest north of Rangoon by a bandit. We were asked to take care of the problem, so we started looking for the stones. But after six months, we couldn't find anyone who had traded with him. One day I found a child playing with a ruby as big as a tangerine. The bandit had been throwing the stones away.
Bruce Wayne: Then why steal them?
Alfred Pennyworth: Because he thought it was good sport. Because some men aren't looking for anything logical, like money. They can't be bought, bullied, reasoned or negotiated with. Some men just want to watch the world burn.

Bruce Wayne: Did you ever catch that bandit in Burma?
Alfred Pennyworth: Eventually, yes.
Bruce Wayne: How?
Alfred Pennyworth: ...we burned the forest down.
