What is the moral lesson Liesel learns in The Book Thief?Does it relate to death?

One of the moral lessons that Liesel learns in
The Book Thief is that even in the heart of tragedy, good is still
possible.  Liesel is no stranger to grief--many of her family members are killed and her
mother has to give her away to the Hubermanns so that she can survive.  The Nazi regime
creates a constant threat to everyone around Liesel, but from Hans, Liesel learns that
people can still be good at heart.  Hans takes in Max even though this act of kindness
could bring death to the entire family.  Similarly, when Hans sees starving people being
marched to Dachau, he offers one of the men a piece of bread for which he is beaten. 
Hans risks his own safety to follow what he believes to be morally right.  As a result,
Liesel learns that good can withstand evil.
