Although Pancho killed Americans and many Mexicans, he also helped many people. His main objective was viewed as Americans see Robin Hood. Both men stole from the rich, but gave the wealth to the poor.
Pancho did love himself a lot, though. Many times, he would hire American photographers to record or photograph him during battle. In this reenactment, you can see the photographers and what it was like while recording Villa.
