Katniss Everdeen can survive her darkness because she understands the same truth that's expressed in that graffiti in Palestine. Her heart is a weapon, and the way to keep fighting against all the horror and cruelty of the world is to wield that weapon. To keep loving.

a thing may happen and be a total lie; another thing may not happen and be truer then the truth

The whole problem with the world is that fools and fanatics are always so sure of themselves and wiser people so full of doubt.

your heart is a weapon the size of your fist. keep fighting. keep loving

like it or not, what we dress in is a direct reflection of who we are personally, socially, and historically.

And of course, if there's one thing we feel we can take as truth in these books it's Katniss and her narrative. But we should ask ourselves whether even this should be above suspicion. Like all first-person narrators, Katniss is her own editor with her own biases: she chooses how to present herself and those around her. Katniss has a stake in the story she's telling and what that stake is changes how she portrays the events and her emotional reaction to them.
