I'm thinking that even the enforcers have been lied to and brainwashed by the higher-ups. Many of them probably even feel that they're doing the right thing.
Some are guard dogs of the flock. Some are herders, search and rescue, or companions. We Devildogs are those, and also retrievers. Hell is our dogpark, our swimming hole. The fallen are our tennis balls. We don't leave the fallen behind, even if the master has to bring them home. Semper Fi, my friends.
