I love Billy the Kid, he had honor.

In the Cattle War , he was sitting round with his possy , and his best friend came to tell him he was going to fight for the other side, and Billy shook his hand.

As Billy's friend was riding away , one of his possy trained his rifle on him to take a shot and Billy whooped him , saying how dare he take a cheap shot at a man that had the bravery to come and tell them of his defection to their face.
