Quote 46
The Star of David was painted on their doors. The houses were almost like lepers. At the very least, they were infected sores on the German landscape. (8.43)
Being a Jew in these times means being a criminal. There is no move a Jew in Nazi Germany can make that isn't considered a crime.
Quote 47
Although something inside her told her that this was a crime – after all, her three books were the most precious items she owned – she was compelled to see the thing lit. (18.12)
She's at the Hitler's birthday celebration book burning, of course. Humans will be fascinated with crime so long as it exists. But, Liesel could have at least thought about stopping the books from being burned. Why doesn't this occur to her?
Quote 48
[…] but it was the stealing that cemented their friendship completely. […] it was driven by one inescapable force – Rudy's hunger. The boy was permanently dying for something to eat. (24.63)
This highlights Himmel Street poverty, which has only increased since the war began, due to rationing. It's also due to the fact that there were no more Jewish customers. Again, Rudy and Liesel's criminality seems the opposite of criminal, other than the ham-stealing incident.
