In the Middle East, no one is exempt from the revenge rules or emotions.

Peter O'Toole said it best over 40 years ago...

Tafas, Lawrence's escort, is shot down in cold-blood by the black-robed Bedouin for drinking at the well owned by a rival tribe. Through this ugly, ferocious act of ancient Bedouin tribal warfare, a fearless Lawrence is introduced to Sheik Sherif Ali Ibn el Kharish (Omar Sharif):

Sherif: ...You are angry, English. He was nothing. The well is everything. The Hasimi may not drink at our wells. He knew that. Sa'lam.

Lawrence: Sherif Ali, so long as the Arabs fight tribe against tribe, so long will they be a little people, a silly people, greedy, barbarous, and cruel, as you are.

A little people, a silly people, greedy, barbarous, and cruel. That pretty much says it all.
