Maybe it means: you’re the evil man, and I’m the righteous man, and Mr. 9mm here, he’s the Shepard protecting my righteous ass in the Valley of Darkness. Or, it could mean: you’re the righteous man, and I’m the Shepard, and it’s the world that’s evil and selfish. I’d like that, but that sh** ain’t the truth. The truth is: you’re the weak, and I am the tyranny of evil men. But, I’m tryin’, Ringo, I’m trying real hard to be the Shepard.
