“When we recruit sources, we pull them in with a sin, something they’ll do anything to keep buried, but when you cross the line, you recruit yourself. Then you start doing worse and worse things to keep it all buried. And then, over time, the bodies under the floorboard, they eat away at whatever’s left of your conscience. Sometimes it’s better to let the bad guys get away with it than it is to be the one who gets away with it.”
