Guess who spoke this line. You can't? Yeah, it could come from almost any character in the book, couldn't it? This quote actually comes from a very minor character, one of the youngest—one of the boys Chigurh pays for a T-shirt. By covering up for Chigurh, this boy allowed the bad guy to get away. He might live with that guilt forever.

Bell seems like a person who believes in karma, although he probably wouldn't use a hippy-dippy word like that. But from this line, we see that he believes that choices have consequences. At least, that's what he has to tell himself. In this book, we see people who make no bad choices be killed, and we see people who make horrible choices (like Chigurh, who chooses to kill victim after victim) live to choose again another day. But it's also possible that karma works in mysterious ways; maybe Chigurh will get what's coming to him one day.
