What is the purpose of langston hughes "salvation"?

Langston Hughes wrote “Salvation” as a part of his biography to show a huge event in his childhood that changed  his life forever.  He did not want to just express the feelings he had during the event; he wanted to show what and who had changed his life.  Hughes wasn’t necessarily criticizing his aunt and other adults in the passage.

i'm pretty sure you can use the word uproar
