Answer:
Because she sympathizes with the situation that Roger is going through.
Explanation:
Roger almost steals Mrs. Jones' purse. That's because he lives in a precarious situation of great poverty and need. This makes him make extreme decisions, like stealing, to survive. Mrs. Jones, however, recognizes that Roger is not a bad boy and that he is stealing to meet basic needs. She understands the problem that Roger is going through and decides to treat him kindly and instead of calling the police, she decides to help him.
