One of the more evident indications that President Coin was a villain was her decision to put Peeta on Katniss' squad when District 13 took the Capitol. It was clear to everyone involved—even those loyal to her—that Coin's only motivation for this would be to eliminate the Mockingjay entirely.
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.
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.
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.
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.

Why did Snow laugh when Coin died?
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.
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.
It is still possible that she genuinely wants to make Panem a better place, but her methods become inhumane. Coin feels threatened by Katniss' rebellious nature. In the end, her own delusional idea of Panem is her undoing, since she ignorantly trusts that Katniss is okay with her being the new president of Panem.
Lucy Gray would've been 81. In "The Hunger Games" books, Katniss describes President Coin as appearing about 50, which would make her too young to be Lucy Gray. However, it doesn't mean Coin isn't related to the former District 12 tribute.
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.
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.
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.
Peeta decides, though, that he will go out on his own to act as a diversion in case Katniss and the others need it. Gale gives Peeta his nightlock pill in case Peeta's captured. They leave early in the morning, bundled up and styled by Tigris. Cressida and Pollux go first, leading the way to the City Circle.
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.
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.
In the movie, Snow and Baird develop a friendship as mentor and tribute after Lucy Gray saves Snow's life during an attack on Panem. After being sent to District 12 as a Peacekeeper in the aftermath of the 10th Hunger Games, Snow starts to deepen his relationship with Lucy Gray, which develops in a more romantic light.
Katniss also realizes that, even though Gale had nothing directly to do with Prim's death, the bombing trap that killed her was based on one of his designs, which makes both him and Katniss feel he is somewhat responsible.
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.
He helped end the Hunger Games, but he still supported re-establishing them to punish Capitol children. In the end, Plutarch was like most all the other The Hunger Games characters - filled with a mix of both goodness and evil.
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.
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.
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.
