Unable to find Peeta and hearing a cannon, Katniss nearly attacks Finnick, suspecting his betrayal, but he reminds her to "remember who the real enemy is." Katniss attaches the wire to an arrow, firing it into the arena's roof just as lightning strikes.
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.
Finnick was willing to give up Mags to save Peeta because he needed to, to convince Katniss they were on the same side. He receives a large cut in his leg when he was trying to save Peeta. During the events of Mockingjay, Finnick shows concern for Peeta, and goes out of his way to save Peeta's life again.
Katniss is unfazed by his flirting, and admits that while he is attractive, she has never been drawn to him. At first, Finnick appears to be another shallow puppet of the Capitol's.

Why does Mags kiss Finnick?
Chia Mags kisses Finnick on the mouth to briefly let him know that this is the last time she will see him. It's her way of saying "Goodbye" but in a more affectionate way.
Katniss made the choice to build her future with Peeta. If she didn't love him, she wouldn't have made that choice. Katniss made her whole world about getting the people she cared about to the next day, her choice to survive with Peeta proves her love for him.
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.
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.
Katniss here's this and understands that even though she may not love Peeta (then) that it's one less person who has to die. (At least that's what I have always thought.) Katniss realizes that if she pretends to be in love with Peeta people will want the capitol to let them survive.
After winning the games, Finnick was forced into prostitution by President Snow. He was blackmailed into going out with wealthy citizens of the Capitol for the safety of his loved ones, such as his District 4 sweetheart and fellow victor Annie Cresta (Stef Dawson).
Also, Mags was Finnick's mentor, and most likely helped mentor Annie. They would have all lived together in the District 4 Victors' Village. Much like how Katniss, Peeta, and Haymitch became family, it is probable Mags, Annie, and Finnick did as well, so Mags may have felt a maternal kinship towards the younger two.
Finnick learned many secrets, including that Snow, in his rise to power, poisoned his adversaries but to divert suspicion often drank from the same poisoned cup followed by an antidote that only Snow used. Segments of the propo of Katniss and Finnick are aired.
Given that she is willing to make the ultimate sacrifice to protect Peeta, it's safe to assume that the Morphling was committed to the rebel cause. Like the other victors, she knows the power that Katniss has as a lightning rod for the rebellion, and she knows that Katniss will not help without Peeta.
Who is the first person Katniss intentionally kills?
Katniss kills Glimmer, Marvel, and Cato in The Hunger Games. Glimmer's death occurs by chance. Katniss drops a tracker jacker nest on the Career Tributes' camp while they are sleeping, and Glimmer is stung to death before she can get away. Marvel is the first person that Katniss intentionally kills.
Finnick Odair is the youngest winner in history, winning at just 14 years old. District 2 has the most overall winners, producing "Career Tributes" and having the highest number of victors among all districts. Warning: Spoilers ahead for The Ballad of Songbirds and Snakes!
As a Career tribute, Finnick won the 65th Hunger Games at the age of 14, where he was mentored by the previous District 4 victor, Mags. During the 74th Hunger Games, he served as mentor alongside Mags for District 4, as revealed in Mockingjay when he became the expert on Peeta's memories of his two times in the arena.
One of the more tragic things about Finnick's story is that, upon winning the Hunger Games at just 14 years old, President Snow forced him into prostitution to exploit the Capitol's obsession with him, threatening the lives of Finnick's family members should he fail to comply.
Mags, an eighty-year-old woman, volunteered for the 75th Hunger Games in the place of Annie Cresta, becoming a tribute alongside Finnick Odair, whom she mentored in the 65th Hunger Games and (according to the book and film) practically raised.
She's half-family, i.e., sorta or partially family, because there's affection but not blood relation. There are literally only 2 people in Finnick's family (Mags and Annie), and Mags is 1 of them.
During an interview Katniss and Finnick shot to distract the Capitol from the rescue team, Finnick reveals President Snow kills his enemies and allies who can become threats to him. He also reveals that Snow forced Finnick into sex trafficking, selling his body to wealthy Capitol citizens for high prices.
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.
It's only implied that they get it on via snuggling and other affectionate acts in close quarters — but if you have read the book, they really imply that they took their relationship to the next level.
