Without reading the book, it's easy to overlook this detail. However, those familiar with the book know that Katniss was suicidal and depressed after she had avenged her sister's death.
Given the situations she is living under, her depression and inability to cope makes some sense, but it leaves Katniss with a lot of responsibility. It's definitely unfair that Katniss has to worry about providing and caring for her family.
By killing Coin, Katniss ensured a chance for a peaceful and fair country, avenged her sister's death, and liberated Panem from the fascist government.
Who is the first person Katniss intentionally kills?
Katniss kills Glimmer, Marvel, and Cato in The Hunger Games. Glimmer's death occurs by chance. Katniss drops a tracker jacker nest on the Career Tributes' camp while they are sleeping, and Glimmer is stung to death before she can get away. Marvel is the first person that Katniss intentionally kills.
Katniss's focus on survival and her family's safety prevented her from fully considering romance, but her feelings for Peeta and Gale diverged in the end. Katniss ultimately chose Peeta because he understood her trauma and she didn't want to lose him, proving her love for him.
Gale was responsible for creating weapons that would trigger a second wave of bombs to target first responders and combat healers. This invention potentially ended up killing Prim, but even if he wasn't directly responsible, Katniss found this tactic so abhorrent that she lost her affection for him.
Although she will never know for sure, Katniss does recognize that she cannot be with Gale. She will never be able to forgive him for his idea — the parachute bombs — that killed Prim.
She then attempts to kill herself with the suicide pill attached to her uniform, but Peeta stops her. She is arrested and placed in solitary confinement, where she attempts to commit suicide by starving herself and overdosing.
Snow laughs after Katniss killed Coin because he enjoys the irony of the situation. He avoided the official execution ceremony, even though Panem's citizens still take their revenge on him, while Katniss ends up snatching away the victory and power that Coin thinks she has successfully secured.
Snow can't stand to see a young woman betray a young man's affection—his view of what happened 65 years ago. And so he takes out his old, festering wound on Katniss.
Answer and Explanation: Prim is killed by a bomb at the very end of the battle. Alma Coin sees an opportunity to turn the Capitol troops against Snow, and she decides the resulting loss of life from her plan is a worthwhile price to pay.
Even in the Games, she was trying to save the one she loved, and now that both factors were taken from her life, it made sense that she would question her existence. Additionally, Katniss was in great pain and still suffered from the trauma of the war. Death to her also meant a relief.
Essentially, Katniss was afraid that if she was to kill President Snow, then the whole revolution fails, and the rivalry would still continue. Therefore, Katniss had to sacrifice by killing Coin in order to end war, and knew that Coin couldn't do anything better than Snow to save the Panem.
People who suffer from PTSD can also experience trouble sleeping, which both Katniss and Peeta deal with, exhibit self-destructive or reckless behavior or can be aggressive and irritable. Both tributes also have trouble controlling themselves and often react aggressively to situations that upset them.
While she manages to escape both Games with her life, she is left suffering significant psychological distress and displays symptoms consistent with post-traumatic stress disorder (PTSD).
How Katniss Deals with Her PTSD. It's no surprise that Katniss becomes traumatized—after all, the Hunger Games are the perfect breeding ground for PTSD. Severe, life-threatening, interpersonal violence as well as witnessing atrocities and killing enemies in combat are particular risk factors for the disorder.
By killing Coin, Katniss ensured a chance for a peaceful and fair country, avenged her sister's death, and liberated Panem from the fascist government. The Hunger Games franchise is still an iconic series of books and movies, with the latter truly cementing the property as an international phenomenon.
According to the star behind Effie, Elizabeth Banks, she and Haymitch's Woody Harrelson improvised the scene. Considering she's been adamant about the characters having some romantic connection, it only makes sense that they'd share a goodbye kiss. It's very on-brand for Effie, as well.
The problem was that Gale was the one who created the firebomb devices. Despite not being fully responsible, Katniss couldn't overlook his possible involvement. Katniss returned to District 12, where she reunited with Peeta after she couldn't allow herself to fully forgive her childhood best friend.
Katniss feels betrayed, most of all by Haymitch, who used her and Peeta. Eventually she wakes to find Gale there. He's badly injured and tells her the Capitol bombed District 12 after the Games. He got Prim and Katniss's mother out in time, but the District 12 is gone.
Their roles as star-crossed lovers help them gain sponsors and survive the games. Once the games begin, Peeta forms alliances with the Careers, which Katniss does not initially realize is part of his plot to protect her. After Peeta tells Katniss to run from Cato, Cato stabs Peeta in the thigh and leaves him for dead.
Gale does not marry anyone in The Hunger Games. He and Katniss talk about running away together and starting a new life in the wilderness, but they never officially marry.
Katniss's focus on survival and her family's safety prevented her from fully considering romance, but her feelings for Peeta and Gale diverged in the end. Katniss ultimately chose Peeta because he understood her trauma and she didn't want to lose him, proving her love for him.
It's only implied that they get it on via snuggling and other affectionate acts in close quarters — but if you have read the book, they really imply that they took their relationship to the next level.
