HELP!! What are three themes of to kill a mocking bird and what evidence shows it

The novel To Kill a Mockingbird, written by Harper Lee in 1960, is an American literary classic, and recounts the life of a girl in the context of the Deep South of the early-1930s, when racial segregation towards African Americans was on the rise.

Thus, the three most important themes that this novel develops are:

- Racism and racial segregation, as the novel takes place in Alabama, which was one of the epicenters of segregation in the context of the Jim Crow Laws sanctioned after Reconstruction.

-Injustice, as Tom Robinson is accused and blamed for a crime he did not commit, for the simple reason of being a person with black skin.

-Ethics, as the girl's father, Atticus Finch, is a lawyer who defends African Americans in a totally hostile context towards them and their work, putting their reputation and even their safety at risk.

honestly you should not write it the word placement is not right and this does not sound right so i think you should write it this way. the life lessons i refused to learn, taught me the hard way this sounds way better you should try it! hope this is very !
