This really ruined my enjoyment of the Hunger Games Trilogy. Katniss, you see, is supposed to be portrayed as this consummate survivor(she survived one and a half Hunger Games and managed to avoid starving by poaching in the woods), but for some reason she has this "unfortunate sentimental streak"(President Snow describing Seneca Crane) in her. Let's begin. 1)If she had the heart to kill Peeta, there wouldn't be a war. She would be a clean victor and enjoy the money for the rest of her life. Instead she plucked some nightlock from her pouch and started Panem War Two. And also sent the Capitol racing to kill her and Peeta, as well as their families. 2)She was alone with President Snow in the study. It would have been beyond easy to attack him and kill him, or at least disable him until she can pull out her knife and kill him properly. 3)She should have backstabbed Johanna Mason and Finnick Odair the moment she got the chance. They're too good at their respective weapons to be allowed to live. 4)She should have let go of her obsession with Peeta, because worry over him drives her near-crazy. 5)She should have immediately agreed to be the Mockingjay. There is no harm and it will help the rebels win the war. There's no point making the Mockingjay Deal-if the victors were really as innocent as she thinks, they would be found Not Guilty and let go anyway. "But she can't take the slightest risk that Peeta might die," I hear you cry. Well, see point four. 6)She should have shot Peeta the moment Coin transferred him to her team. For God's sakes, you can't have a loose cannon-no, not even that, a pure psycho running amok as you're going on a suicide mission to kill Snow! 7)She should have shot President Snow, not President Coin. Although Coin may be power hungry, she IS a damn good leader. And Katniss is too beloved for Coin to have assassinated. Hell, she should even support Coin, because as stated above, she is a damn good leader. And if she supports Coin, Coin has no reason to kill her.
