TKAM chapters.22-25

In chapter 22, i was very shocked when Atticus was confronted by Bob, because i for sure took.it as a.death threat. Why? He won the case, so i dont see a reason, unless he thinks there.is more.to the story than it seems.
In chapter 23, i was also surprised when Jem and Scout were asking to play with Walter Cunningham and Aunt Alexandra said "Because--he-is-trash". I think that it sent a wrong message to them. Also when Jem was talking about Boo Radley and said "Im beginning to underatand Boo Radley stayed shut up in the house all this time...its because he wants to stay inside" i completely agreed.
In chapter 24 and 25 I thought it was very funny when Ms. Stephanie was asking Scout what she wanted to be when she grew up...a lawyer, no she said."just a lady". Then, on page 235 when Atticus said that Tom had been shot my jaw dropped. Especially when Atticus later said "we had such a good chance"... Because they really did.
