If I'm understanding you correctly (sorry, I'm new at this) It sounds like you are describing an accident that either didn't actually happen, or was minor compared to what could have happened. I would call this a "near miss" or "close call"
Explanation:
For example: I had a near miss today when a dog ran out in front of me.
Or: He had a close call when his foot almost slipped over the edge of the cliff.
That they are rich and poor that means more money and less money
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.
