By killing President Coin, Katniss risked her safety in order to not only avenge Prim's death but also gift the people in Panem a chance to live in a peaceful and fair country for everyone. Katniss was incarcerated for a time, and she was sent back to District 12 after she was deemed unsuitable for a trial.
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.
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.
The Life of President Alma Coin: The Real Villain of the Story (Hunger Games Explained)
Why does snow laugh when Katniss kills 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.
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.
She might even be worse than Snow considering the fact that Snow has honor, care for others like his family, and genuinely believed that the Hunger Games were for the greater good, while Coin simply continued the games as an act of vengeance and cared about nobody.
That said, it was stated that an emergency election took place after Katniss assassinated Coin. Commander Paylor, a vital leader in the Second Rebellion from District 8 was elected as Panem's new president.
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.
Using knowledge from the movie and the books, let's break down how The Hunger Games ends. 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.
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.
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.
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.
Katniss blamed Gale for the death of Prim. She would never be able to look at him again without thinking of his part in her death. Gale was the best friend he could have been to her at that moment. He knew her so perfectly to understand this, he knew his chance with her had passed.
At the end of Mockingjay, Gale relocates to District 2 and begins working in the district's government. He helps train replacements for the Capitol's Peacekeepers.
Finally, Katniss was appointed to carry out the execution of President Snow, but she assassinated Coin in his place. Following an emergency election, President Paylor was instated, and Katniss was kept in solitary confinement at the Training Center during her trial in absentia.
However, he did genuinely seem to care about his granddaughter; when she watched Katniss tearfully hugging Peeta in the Hunger Games after Finnick Odair revived him, she said she wanted to love someone that much someday. Snow beamed at her and replied, "And so you shall, my darling. So you shall."
Haymitch Abernathy, the mentor for Katniss and Peeta in The Hunger Games, won his own Hunger Games through smart tactics and outsmarting his opponents. Winning the Hunger Games came at a great cost for Haymitch, as President Snow ordered the death of his family and girlfriend as punishment for his rebellion.
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 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.
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.
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.
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.
