Explain why Liesel gets angry at the mayor‘s wife. Do you think she was too harsh? Why/Why not?

When Liesel visits, Ilsa begs her to take The Whistler, which she does at first. But Liesel feels so angry that she returns and yells at Ilsa, attacking her for being wealthy and arrogant and telling her to face the fact that her son is dead. Liesel throws the book on the ground and sees Ilsa as having been beaten up by her words.

Liesel's tirade against Ilsa is perhaps her cruellest moment since beating Ludwig Schmeikl. Liesel tells Ilsa, who has suffered for years over the death of her son, to get over it and pictures Ilsa's face as bloodied and battered from this verbal abuse. Liesel is genuinely angered about Ilsa firing Rosa, and does not regret what she said, though she later tells Hans that she is going to hell.
