"I follow orders." Because he isn't perfect. Far from it. He does what he's told and asks as few questions as possible. Because the less he knows, the less he's inclined to consider. He does what he's told is best for his country, and he can only hope that some of what he's told is true.

"But I know what I am."

Which, really, is what matters most to him. He knows exactly what he is-- a dog on a leash. He sits, he stays, he speaks, he kills. It isn't something he's proud of, but it's something he knows.

"As long as you know what you are-- do what you want."
