The primary antagonist in Catching Fire is the totalitarian government of Panem, headed by President Snow; under this cruel regime, Katniss and the lives of countless other citizens are controlled, dominated, and oppressed by the harsh, demanding law and its merciless Peacekeepers. Katniss bears witness to much of their cruelty throughout the novel, from her horrified reaction at the execution of the old man in District 11 to trying to save Gale from the deadly whipping in the townsquare. Before Katniss heads to the Quarter Quell, Haymitch warns her "You just remember who the enemy is" and Katniss realizes profoundly that her true enemy is not the other tributes who are trying to kill her, but the all-powerful and corrupt Capitol of Panem (268).
