How do the adult characters in The Book Thief provide a positive role model for Liesel Meminger?

The adults in Liesel's life show compassion to others even
during the most trying of times.  Hans is a major role model for Liesel, and he often
puts his life at risk to show compassion to others.  Hans knows that he will be jailed
or killed for hiding Max in the basement, but he believes that all people have a right
to live, so he takes the risk.  From this behavior, Liesel learns compassion.  And even
though Rosa is often harsh in her words, she also is compassionate to Max and makes sure
that he has enough to eat.  She can hardly feed her own family, but she splits their
provisions to provide for Max.  The Hubermanns similarly opened their home to Liesel
when her mother could no longer care for her, and certainly Liesel sees their sacrifice
on her behalf.  So, Hans and Rosa provide positive role models for
Liesel.
