Final answer:
Link Deas assists Helen Robinson by offering her a job and later ensuring her safety from harassment, reflecting the moral support some characters provide to combat racial injustice.
Step-by-step explanation:
In the novel To Kill a Mockingbird, Link Deas helps Helen Robinson, the wife of Tom Robinson who has been wrongfully accused and convicted of a crime, by providing her with a job after Tom's incarceration. Despite not needing her help, he offers Helen work so she can support her family financially. Furthermore, when he learns that Helen is being harassed on her way to work by Bob Ewell, Link Deas gives her a stern warning to stop such behavior and ensures she has a safe route to travel by escorting her past the Ewell residence. This act of kindness and protection highlights the theme of morality and the few individuals in Maycomb who actively combat racial injustice.
