Katniss’s death in the end is not a result of someone directly killing her, but rather a slow and agonizing process brought on by her own actions. As she is held prisoner in her room, she realizes that the Capitol still has control over her life, even after the rebellion and the fall of President Snow.
With no way to escape or end her own life, Katniss resorts to starving herself. She refuses to eat, slowly wasting away as her body weakens and deteriorates. The hunger becomes unbearable, but she remains steadfast in her decision to take control of her own fate, even if it means sacrificing herself.
During this time of physical suffering, Katniss finds solace in singing. It becomes her way of expressing her emotions, a form of release and a means of holding on to her identity. Through her songs, she is able to convey the pain and despair she feels, as well as the strength and resilience that have defined her throughout the Hunger Games and the rebellion.
As Katniss’s body continues to weaken, she becomes a mere shell of her former self. Her once strong and capable physique is reduced to a frail and emaciated state. The starvation takes a toll on her both physically and mentally, but she remains determined to defy the Capitol, even in death.
In the end, it is the Capitol’s control over her life that ultimately leads to Katniss’s demise. She is denied the agency to choose her own fate, forced to suffer and waste away under their watchful eyes. It is a tragic and poignant ending for a character who has fought so hard for her freedom and survival.
Katniss’s death is a result of her own defiance and refusal to give in to the Capitol’s control. Through starvation and the power of her songs, she chooses to take control of her own fate, even if it means sacrificing her life. It is a heartbreaking end for a beloved protagonist, highlighting the lingering effects of the Capitol’s tyranny even after their downfall.
