Five years ago a girl stole some money from you and she never got in trouble for it. Since then, she has become a much better person. Recently she has been arrested for stealing, but you can prove that she is innocent.
I'm not saying a thing. This is the punishment that she never got five years ago.
Tell her that I'll save her, provided she pays me back the money she owes me.
I'll save her because I know she's a better person now.
I'd save her even if she was still a bad person because I know she is innocent this time.
