In the book, Katniss thinks that Snow wants the children close to the mansion to “form his human shield”—he assumes that the rebels won't bomb his home if it means killing innocent children. However, the rebels outwit Snow by using hovercrafts marked with the Capitol's seal.
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.
Before turning her arrow on President Coin, Katniss was determined to kill President Snow in The Hunger Games: Mockingjay - Part 2 and led a team of rebels into the Capitol to find him. She and Gale made it as far as Snow's mansion, where Snow had announced that children would be allowed in for safety.
It is revealed by Finnick Odair that he poisoned his allies, as he believes that they would become future foes, but he had to drink the poison as well so that he wouldn't attract suspicion. Even though he took antidotes, the poison caused permanent sores inside his mouth that never healed.
President Snow's Panem Address #1 - "Together as One" (4K)
Why did snow become evil?
In the end, Spruce and Sejanus are hanged at the Hanging Tree; Snow feels responsible for Sejanus' death and is wracked with grief. According to Jacobson, Sejanus' death is a "defining moment" that is "essential" to Snow's transformation into the evil President Snow fans know from the original trilogy.
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.
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.
Why does snow not like Katniss? She sparked rebellion against the system he was a part of, and in control of. She made the Captiol look very bad, as a result of the Gamemakers begging her and Peeta to stop trying to eat the berries.
He leaves a single, perfect white rose for Katniss in her old house when she visits what is left of her district. This is a sign to Katniss that she can do nothing without his knowledge, and it serves the purpose of unnerving her.
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.
At one point, Snow used poisons to kill people in an effort to gain more control of Panem. First he drank the poisons, to lessen suspicions, before secretly taking the antidote. He was left with sores that never healed. He wears a white rose in his buttonhole at all times, partially to conceal the smell of blood.
Years later, Katniss will recognize Tigris in Mockingjay – Part 2 (now played by Eugenie Bondurant) as a longtime stylist for the Games. Snow and Tigris have long since fallen out, it seems—we catch glimpses of her disappointment in his ruthless path to power in Songbirds and Snakes.
Black, oily matter spouts like a geyser from the street, billowing between the buildings, creating an impenetrable wall of darkness. It seems to be neither liquid nor gas, mechanical nor natural. So it's a tarlike substance designed to drown people.
And then to top it all off, after working under Coin for probably years, he secretly knew Coin was evil and "planned" (predicted) Katniss would execute Coin all along.
As Lucy leaves for a brief moment to gather katniss, Snow grows paranoid and believes that she will betray him. In the Ballad of Songbirds and Snakes Lucy story, he starts to hunt her across the lake and the novel amps up his neurosis after he's bitten by a snake under a scarf that Lucy seems to have left behind.
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.
The woods are now ruined. Katniss decides that the Capitol views her and Gale's weekly hunting trips — and the one time that Gale unexpectedly kissed her, which Snow knows about — as flaunting her defiance in front of the entire district.
Katniss has just learned that Peeta has romantic feelings for her, and initially she feels she is being used. She becomes angry with Peeta as a result, going so far as to shove him over an urn of flowers.
Gale Hawthorne is Katniss Everdeen's best friend and hunting partner. In order to not cast suspicion on Katniss and Peeta Mellark's highly publicized strategic romance, Gale is presented as Katniss's cousin. He bears a resemblance to Katniss, which makes their cover believable.
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.
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.
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.
