"Don't," Jack says, steel in his voice, and this time he actually looks at Carl. "There probably wasn't anything you could have done, and I don't want to think about what could have happened if you were."

He doesn't know the man he kidnapped. If Carl had been here...would he have taken the first person he saw, or would whatever was controlling him have pointed him toward someone he knew? If Carl had been here, chances were he'd have been on the rescue team. What could he have done if Carl was the one who found him?
