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.
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.
Since the end of Katniss' first Hunger Games, President Snow has been wary of Katniss and the power she wields over the districts. Snow recognized early, from Katniss' first stunt with Peeta and the nightlock berries, that she could mean trouble for his power and control over the Capitol.
While vindictive, he is always honest with Katniss, which helps her believe him when he explains that they have both been outmaneuvered by Coin. He dies choking on his own blood, a fitting death since the bleeding sores in his mouth were caused by the poison that he used to kill his political enemies.
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.
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.
The films, trying to be as faithful to the source material as possible, naturally had to include Finnick's death as well. In this sense, Finnick is the perfect candidate for upping the stakes of the plot via his death, as his hope for a future with his partner Annie made his demise seem even more untimely.
She was also against the games itself, whilst Snow believed the Districts were below him and continued working to implement new aspects of the games. Their relationship was so undesirable that Snow fired Tigris as a stylist personally.
It was here that Snow first heard the mockingjays, taking up the tune after the jabberjays repeated Chance's last words, "Run, Lil, Run!" He took an instant dislike to the birds, an unnatural muttation of the Capitol-bred jabberjays.
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. He has no reason to lie to Katniss. His death is certain, but the future of the Capitol is not.
By allowing Snow to live, however briefly, she's making the statement that she's not the only person those in power need to worry about anymore. Katniss has done her part, and the rest of the population has already been galvanized by her taking a stand.
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.
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 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.
From flattening her nose to having whiskers implemented onto her face, Tigris began looking like a feline creature, combined with her tiger-centric tattoos on her body. At some point between her hiring as a stylist and the 74th Hunger Games, Tigris was fired by Snow and the Gamemakers.
Described as sweet and vulnerable, in the book, it's suggested she sells her body to ensure the family keeps up appearances and stays fed. Tigris is seen again in "The Hunger Games" franchise as an ally to Katniss Everdeen, but much differently. After heavy modifications to her body over time, she resembles a tiger.
However, she was banned from the profession because she received too many surgeries—now, her face looks like a tiger's. Tigris helps Katniss and the other rebels by giving them food and shelter, telling them where President Coriolanus Snow lives, and supplying them with warm clothing.
After winning the games, Snow forced Finnick into prostitution and sold his body to Capitol residents to gain their trust. Finnick only agreed to take part because Snow threatened to torture his loved ones. Even though he bedded several women throughout his time as a victor, Finnick's love for Annie remained true.
Finnick Odair was a male victor from District 4 and the winner of the 65th Hunger Games, making him the youngest Victor ever. Ten years later, he was reaped into the Third Quarter Quell, of which he was one of the survivors.
Both Morphlings die during the Hunger Games in Catching Fire, after the female tribute from District 6 protects Peeta from the monkey mutations that attack the tribute. She dies in Peeta's arms while looking at the sunset.
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.
