The problem was that Gale was the one who created the firebomb devices. Despite not being fully responsible, Katniss couldn't overlook his possible involvement.
In the beginning, Katniss did love Gale. But around the middleish/ending of the story, she finds herself loving Peeta instead. The main reason, though: Gale and Coin were designing a bomb, and Prim was killed by the bomb. After she died, Gale realized it was over with KAtniss.
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.
Prim was among the medics who arrived to treat the victims. Unfortunately, a second batch of bombs were set off, with Prim being killed in the explosions. Gale was not the one to drop the bombs from the hovercraft, but he was one of the key figures to devise the strategy of double bombings.
Hunger Games: Why Katniss Ends Up With Peeta, Not Gale
Who does Gale marry in The Hunger Games?
Gale does not marry anyone in The Hunger Games. He and Katniss talk about running away together and starting a new life in the wilderness, but they never officially marry.
Who does Gale end up with at the end of Mockingjay?
In the Mockingjay movie, Katniss confronts Gale about his role in Prim's death, which he struggles to come to terms with. Katniss, unable to look at him the same way, lets him walk away without a word and eventually ended up living with Peeta.
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.
Deceased. Primrose Everdeen - Blown up by President Coin's parachute bombs. Messalla - Melted in an unknown pod that trapped him before burning the flesh off him.
The double bomb that kills Katniss Everdeen's sister, Primrose, was designed by two rebels: Beetee and Gale, Katniss's lifelong friend. Previously, Gale had explained that the double bombs are designed to appeal to mankind's weakness for compassion.
Although she will never know for sure, Katniss does recognize that she cannot be with Gale. She will never be able to forgive him for his idea — the parachute bombs — that killed Prim.
When Katniss comes home to District 12, Gale immediately confesses his love for Katniss, and she realizes she might have feelings for him, too — but she can't explore them, because she has to continue her fake relationship with Peeta or else her entire family, including “cousin Gale,” will be killed.
Katniss's focus on survival and her family's safety prevented her from fully considering romance, but her feelings for Peeta and Gale diverged in the end. Katniss ultimately chose Peeta because he understood her trauma and she didn't want to lose him, proving her love for him.
Gale is jealous of Peeta and the relationship he has with Katniss, and he wants Katniss to decide between them, though he doesn't press Katniss during her recovery in District 13. Gale is an excellent hunter and excels at setting snares and traps.
Peeta, Annie, and Beetee vote no, while Johanna and Enobaria vote yes. After some thought, Katniss demands to kill Snow. Once she receives an agreement, she votes yes, for Prim. Realizing something is up (as Katniss would never do that), Haymitch votes yes, too.
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.
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.
Prim tried to stop Katniss since she knew she would most likely not survive the horror of the Games; but Gale Hawthorne held her back. Katniss' bravery was strong in this part. Gale taking Prim away at the reaping.
Prim was among the medics who arrived to treat the victims. Unfortunately, a second batch of bombs were set off, with Prim being killed in the explosions.
While Prim is caring for the wounded, a second set of bombs go off, killing her, along with everyone around her. This act of treachery and shameless targeting of the innocent is what finally turns President Snow's guards against him. They believe he is to blame, when in reality, Alma Coin was responsible.
Even if Gale didn't intend to murder Prim specifically, he certainly intended to murder somebody. The two-phase bombs that he and Beetee invented were very clearly made with the intent of targeting medics and other civilians trying to save those wounded during the first phase of bombing.
Devastated and left mentally and emotionally stranded , Johanna spent the next few years in isolation, wallowing in her sorrow and trauma. During this period of time, she served as a mentor for the tributes reaped in her district.
Gale is jealous of Peeta, even in his altered state, and Katniss has always been conflicted when kissing Peeta because of Gale. They have faced the truth together, and Katniss feels she and Peeta may never be together again, so in a vulnerable moment, she kisses Gale.
The Hunger Games series, much like Harry Potter is for young adults, and the themes and motivations are not hard to understand. Katniss NEVER hated Peeta. She figured she'd have to kill him to survive and had no desire to like him because of that.
