Katniss Everdeen seems a cold character, often defined by her less-positive traits: her lack of empathy, selfishness, and anger. She is emotionally distant to all but a few—and yet, so many become endeared to her. The rare times she allows someone close, when she reaches out to them physically and emotionally, are meaningful; once she lets a person in, she will likely kill—or even die—for them. It’s only those she trusts not to burn that she will touch.
From the mine explosion that kills her father to the war she becomes a figurehead of, she finds herself protecting those around her, even the people who stoke her anger more than anything else. She volunteers for Prim, is willing to sacrifice her life for Peeta, stocks up on white liquor for Haymitch, risks punishment to help her prep team imprisoned in District 13, and on and on. Most of her life is driven by the need to keep those she can safe and secure, despite her fears of getting hurt or hurting others through her actions.
