Sheep, Wolves and Sheep Dogs
"There are three types of people in this world: sheep, wolves and sheep dogs."
As spoken by Chris Kyle's father in the Clint Eastwood directed film "American Sniper" (2014), said to be "loosely based" on the real live story of Christopher Scott Kyle 1974-2013. The real Kyle was a highly decorated Navy SEAL sniper who served four tours in Iraq with over 150 confirmed kills. A hero in any sense of the word.
