Answer: think that Katniss had every right to be suspicious of Peeta in the first HG. Her survival was based on her living and him not killing her. His connection to her made her a possiblele target of him. He had gotten beaten by his Mom for helping her. The games would be a perfect time to get revenge without being punished for it. Anyone who was in the games would have to face growing paranoia, and in knowing that she would most likely be dead in the next few weeks, she was forced to think of all of the things that would try to kill her. After all, he DID end up going with the careers to try to hunt her down. On that fact alone, I feel like Katniss should have killed Peeta when she found him. Not saved him. (Unpopular opinion, I know but a rational one for her position.) Tending to him only made her weak and vulnerable. The games would have been an easy win without him, AND she would not have been criticized for killing him since he was injured that badly. It would have been a “mercy killing”. Buuuuut nooooooo. She decided to produce a fake romance that ended up hurting her in the long run more than if she had just eaten the berries and died. All of the deaths around her could have been prevented had she been a good little trubute and just cut her losses.
