What is Miss Stephanie Crawford's reaction to the death of Tim Johnson?

Miss Stephanie didn't place a great deal of importance on Atticus' heroics and chose to accentuate the negatives.

Miss Stephanie said, “Uh, uh, uh, who’da thought of a mad dog in February? Maybe he wadn’t mad, maybe he was just crazy. I’d hate to see Harry Johnson’s face when he gets in from the Mobile run and finds Atticus Finch’s shot his dog. Bet he was just full of fleas from somewhere—”

Miss Maudie said Miss Stephanie’d be singing a different tune if Tim Johnson was still coming up the street, that they’d find out soon enough, they’d send his head to Montgomery.
