Katniss and President Coin didn't get along during their time in District 1, with Coin not believing that Katniss had what it took to lead a rebellion. Coin appeared to be a fervent supporter of the Rebellion, but she took advantage of the movement to further her own political interests.
She personally assigned Peeta to join the squad despite the fact that his hijacking had brainwashed him into trying to kill Katniss. This was presumably an attempt on Coin's part to dispose of the girl amid the battle, making her a martyr and preventing her from becoming a threat to Coin's authority after the war.
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.
The Life of President Alma Coin: The Real Villain of the Story (Hunger Games Explained)
Who killed Prim Hunger?
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.
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.
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.
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.
President Alma Coin is the main antagonist of Mockingjay, the final novel of The Hunger Games trilogy. She is the president of District 13 and is very corrupt and in some ways worse than President Coriolanus Snow.
Did Gale mean to kill Prim? No, Gale did not mean to kill prim but he still designed the bomb. But, although he holds a small fraction of responsibility, he never meant for Prim to get hurt.
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.
She expected their years of friendship would make it harder to kill. But she knows her one and only true ally is Peeta, so she decides she must kill Finnick now. Katniss climbs down from the tree, determined to kill him now before he has the chance to kill her.
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.
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.
Peeta, Annie, and Beetee vote no, while Johanna and Enobaria vote yes. After some thought, Katniss demands to kill Snow. Once she receives an agreement, she votes yes, for Prim. Realizing something is up (as Katniss would never do that), Haymitch votes yes, too.
President Alma Coin's proposal, exposing her villainous nature. President Alma Coin is the main antagonist of Mockingjay, the final novel in The Hunger Games trilogy and both of its 2014 and 2015 film adaptations, The Hunger Games: Mockingjay – Part 1 and The Hunger Games: Mockingjay - Part 2.
Did Paylor know about Coin? When Katniss emerges, Paylor asks her, "Did you find what you were looking for?", and Katniss holds up a rose, which Paylor takes as an affirmative response. This seems to imply that Paylor was somehow aware of Coin's betrayal and wanted Katniss to find out.
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.
It became clear then that Coin had the same mentality as Snow. To her, children were a tool to be used against those that loved them. They were chess pieces to be maneuvered and sacrificed. If Coin were willing to kill Capitol children in the Hunger Games, she would undoubtedly be willing to in a war.
Why did Peeta stop Katniss from eating the Nightlock?
3) He stops her taking the nightlock pill after she kills Coin. He knew her well enough to know that not only would she try to kill Coin but that she would then try to kill herself straight after with the nightlock pill.
Control: As the leader of Panem, President Snow wanted to maintain his power and control over the districts. Katniss became a symbol of rebellion and hope for many people, which threatened Snow's authority.
During the supposed execution of Snow, she instead shoots Coin, due to her being responsible for Prim's death. She then attempts to kill herself with the suicide pill attached to her uniform, but Peeta stops her.
He has betrayed her and is betraying all of District 12 by buddying up with the Careers, whom she calls the "Capitol's lapdogs." She decides that if the Careers don't kill him, she'd be more than happy to. Then, she wonders why Peeta hasn't told them about her bow and arrow skills yet.
What does Peeta whisper to Katniss when they reunite?
Then, he opens his eyes. He has camouflaged himself in mud, leaves, and vines. He jokes with her, whispering that it's okay to kiss him since they're madly in love, but once Katniss begins to clean him in the stream, she can see how weak he is.
