Katniss starts the book with little awareness of sexuality, caring little about being physically attractive but through the book you can see her awakeing.
In the relationship of Katniss and Rue we can see love and friendship. In the relationship of Katniss and Peeta its the same although there are so brutal things that happen and the temporary nature of such alliances.
Without the love to her sister Katniss never would join the Hunger Games voluntarily.
Without the perseverance present, Katniss, her sister, and many others would have died very early. In the Hunger Games, this trait is very important to not lose immediately.
Respect is an important value then build friendships and familiar relationships and without respect one would blindly approach a thing and often lose. In addition, respect for nature is very important because the Hunger Games show what kind of power nature can have.
Katniss respects the other member of her District and out of this reason she gets respect from other people
