If you’re talking about To Kill a Mockingbird:
The rabied dog was killed by Atticus when the sheriff asked him to take the shot. Atticus was against guns and taught his children that guns were not needed. The children however, found out that Atticus was a very good shot in his childhood, this is the reason why he was asked to take the shot. When he shot the dog, he overcame his problem with guns, and showed courage to even shoot the gun. When mrs Dubous died, the courage was shown through both of the children, especially Scout since she did not need to go to the house with her brother every day. After her death, the children learned that Atticus only made them go to her house after school everyday because he knew she was going to die and she deserved to have someone by her side when it happened. So even though the children were scared of her, they faced their fears to help her enjoy her last few days on earth.
The candies are a symbol of comfort for Lilia, by throwing it away Lilia feels are she is independent and grown up and does not need the candies.
