In his speech to the jury, for whom does Atticus say he has pity?

the Chief Witness for the State

Atticus has pity for Mayella Ewell. Although she is the accuser of an innocent man (Tom Robinson), she herself is a victim. Mayella is a victim of circumstance and, in particular, a victim of her father Bob. Mayella is abused and probably in the worst way (if one does the math about all the small kids of Ewell it becomes apparent, Yuck!).
