Scout is told this because Scout is mad at Miss. Caroline because she told her not to read. Scout sometimes cannot understand why people are the way they are. Atticus is the one that has to teach her these things because her mom passed away when she was young. In the novel this quote associates with many people such as Boo Radley, Mrs. Dubose, Mayella Ewell, Mr. Dolphus Raymond her brother, Jem and many others. This quote can be bonded with many people and is the most predominant quote in this novel.
The quote connects with Boo Radley because of numerous of reasons. One of them is that he is an outcast in the neighborhood and no one can understand him clearly. If you considered this from his point of view then you will see the world as a dangerous place. You would also think that people think you are eccentric and think that they won't like you. You would be a child's nightmare without even doing anything to them.
The quote “You never really understand a person until you consider things from his point of view” also can be allied with Mrs. Dubose. Mrs. Dubose is an angry nasty person to many people, but if you take your time and think about it she is having a hard time fighting off morphine. Since she is fighting off morphine she is very depressed and cannot hold her anger, so she yells the kids. You can admire her courage to fight morphine to stop her addiction.
I think that Mayella Ewell is the person that is most affected by this quote because of the way she has to life and abide by. She is abused by her father, Bob Ewell. She is also very lonely and unhappy. She has no education because Bob Ewell takes the money from the government and buys whiskey or other alcoholic items. In the court if I was Mayella I would have done sadly what she would have done, because she would of have been beat and abused if she hadn't lied in court about the case. It was not a choice for her, so it couldn't have been her fault.
