Because his father wasn't much of a dad and his mom died. He was on the streets at age 10, bragging about the fact that he got arrested for the 1st time, and he got arrested a lot after that. He couldn't seem to find his way and didn't like his life. He broke law just because he wanted to show that "he didn't care if there was a law or not."
The authors use of figurative language such as similes and metaphors helps to show comparisons between the the room and the public sphere and how she is trapped in the her home just like the lady in the yellow wallpaper.
Answer:
Sheriff Tate said that Bob Ewell killed himself and fell on his knife and that is how he died but the true version is that Boo actually did it to save Scout and Jem, but he didn't want people to know because he likes to keep to himself and didn't want to be known as a hero so that's why Sheriff Tate covered up for Boo and told everyone Bob killed himself. Hope this helps!!!
