Perhaps there was a curse or some dark magic at play. A curse that made the hunters see Percy as an enemy when he was actually an ally, leading to his untimely death.
One possibility is that there is a prophecy that involves Percy and the hunters in a way that the hunters misinterpret. They believe that by torturing Percy, they can prevent some great disaster. However, Percy is actually an important part of the solution, not the problem. As the story progresses, he could start to communicate with some of the more sympathetic hunters and try to make them see the truth.
In the fanfiction, it could be that Kakashi is being too hard on Naruto during training. He might be pushing him beyond his limits without proper explanation or support, causing Naruto to feel frustrated and angry. Naruto is a determined character, but everyone has their breaking point.
Well, 'Percy Among the Hunters' is a fanfic that stands out. It begins with Percy being thrust into the world of the Artemis Hunters. The author does a great job of showing Percy's initial confusion and then his gradual acceptance of the Hunters' ways.

One reason could be jealousy. Maybe she's jealous of the magical world that her sister Lily was a part of. She might feel left out or inferior, which could lead to her anger.
One possible reason could be her child's unfair treatment in the military, like not getting promotions they deserve.
Another reason could be if someone were to slander or disrespect his late mentor, like Iruka or Jiraiya. Naruto holds these people in high regard, and any negative remarks or actions towards them would likely enrage him.
Another reason could be related to school work. If there are new rules in Hogwarts that she deems unfair regarding academics, like restrictions on library access or new grading systems that don't reward hard work properly. Hermione is all about learning and fairness in education, so this could really make her angry.
Perhaps it's due to his discomfort with sudden changes or surprises. Bilbo is a hobbit, used to the simple and predictable life in the Shire. In fanfics, when he's exposed to the chaos of the outside world, like unexpected magic or the presence of strange creatures, he might flinch as a reaction to this discomfort. This shows his struggle to adapt to new circumstances outside his comfort zone.
