She is the President of District 13 and the leader of the rebellion against The Capitol. However, it turns out that she is a corrupt and ruthless woman who is even worse than President Coriolanus Snow.
Alma Coin was the true villain of The Hunger Games, with Katniss actually seeing her as more of a threat than Coriolanus Snow. At the same time, it was Snow who was made out to be the bad guy in previous movies, making some question why Katniss killed Coin and spared him.
In The Hunger Games series, Katniss killing President Coin instead of President Snow surprised many. Still, it was because Coin was revealed to be a ruthless leader with her own political interests.
Was President Snow lying about Coin? She remembers that they did indeed promise not to lie to each other anymore, and she realizes that Snow wasn't lying to her about Coin's role in the parachute bombing.
Coin killed Prim to destroy Katniss because, as Boggs (Mahershala Ali) explains before his death, Katniss is her biggest threat to maintaining her power over Panem because of the influence Katniss has over the people.
What if Katniss Killed Snow Instead of Coin (Hunger Games Theory/ Fan Fiction)
Why did Snow laugh when Katniss kill Coin?
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.
Before the Capitol battle, Gale had explained to Katniss his series of bombs designed to feed off human compassion: a small bomb would go off, and then when medical aid rushed in, a second bomb would go off, killing those people as well. Incidentally, it's this exact type of bomb that took Prim's life.
It is likely that he is a relative of Hilarius Heavensbee. In the Mockingjay - Part 2, Plutarch appears to smile as he looks at Coin's dead body, suggesting that he approved of her death.
Peeta is held back while the other rebels are sent to attack the Capitol, but he is later sent to join them as a member of Katniss's group of sharpshooters, which Katniss suspects is because President Coin sees her as a political rival and wants Peeta to kill her.
After reading the book and watching the film, it seems clear that Lucy Gray realizes Snow was responsible for the death of his friend Sejanus Plinth (Josh Andrés Rivera). If Snow could sell his best friend down the river for personal gain, it was only a matter of time until he did the same with her.
Katniss searches his eyes for signs of emotion but only finds amusement in them. She remembers that they did indeed promise not to lie to each other anymore, and she realizes that Snow wasn't lying to her about Coin's role in the parachute bombing.
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.
What did Peeta take from Katniss after she killed Coin?
In the aftermath of killing Coin, Katniss tries to take her nightlock pill but Peeta stops her, a parallel and inversion of their attempted “suicide” in the first book.
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.
She later realizes, after a conversation with the imprisoned President Snow, that President Alma Coin sent Prim to her death (which was caused by a hovercraft by the rebels) both to sway the Capitol citizens to Coin's side by making them think Snow was bombing the children, and to swing Katniss to her side through the ...
Katniss speculates that Coin deliberately sent Prim to die in the Capitol bombing in order to fully gain her trust, but it's never outright confirmed or denied.
Such encouragement is what Katniss needs as she continues her development as the Mockingjay. When Boggs tells her not to trust “them,” he is possibly referring to Coin, who Boggs has already said is afraid of Katniss because Katniss hasn't given Coin a full-hearted endorsement.
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.
Where his movie character was calm and self-assured, his personality in the books was much more like the other clueless Capitol citizens. Regardless of which, Plutarch Heavensbee played an essential part in Panem's rebellion and contributed significantly to Katniss' survival.
President Alma Coin presented herself as Panem's salvation in The Hunger Games, but several moments in Mockingjay hinted that she was an even worse villain than President Snow.
While Prim is caring for the wounded, a second set of bombs go off, killing her, along with everyone around her. This act of treachery and shameless targeting of the innocent is what finally turns President Snow's guards against him. They believe he is to blame, when in reality, Alma Coin was responsible.
In the end, Katniss and Gale grew apart, as many childhood friends and young loves do. She needed something different in her life, and with Gale's link to Primrose's death, Katniss found a reason to cut ties. If Katniss ever wanted to find comfort again, she knew she had to return to Peeta for the long term.
