What does Sheriff Tate say would be a sin in To Kill a Mockingbird by Harper Lee?

The sheriff says that sending Boo to court for killing Bob Ewell would be a sin because every lady in maycomb would be knocking on his door giving him cakes for saving Scout and Jem, and that would just kill Boo because he is so shy. It would be a sin to make someone so uncomfortable for only helping the children..
