Another reaction could be that she pretends to be compliant while actually planning her escape and the downfall of the Death Eaters. She could use her position as a slave to gather information about their plans and weaknesses, all the while biding her time until she can turn the tables on them.
She would probably first try to resist. Hermione is known for her strong will, so she'd likely fight back using her magic skills, even if it's a losing battle at first.
She could face legal issues in the wizarding world. Killing is not taken lightly, even if it's Death Eaters she's killing. There might be a trial to determine if her actions were justified. If the wizarding authorities are corrupt or influenced by the wrong people, she could even be wrongly convicted.
A possible plotline could be that a Death Eater discovers Hermione has knowledge of a powerful spell or magic item that could help them overthrow Voldemort. So, they save her to get that information. For example, she might know of a way to break a powerful curse that Voldemort has placed on them.
One way it could develop is through the use of dark magic coercion. Maybe a powerful Death Eater discovers Hermione's intelligence and decides to use Imperius Curse to make her his slave. He could force her to use her magic skills for his evil purposes, like brewing dangerous potions or stealing valuable magical artifacts.
Well, in some fanfictions, Hermione might use her superior intellect. She could outwit the Death Eaters by setting up elaborate magical traps. For example, she could use transfiguration magic to create objects that suddenly turn into something dangerous when the Death Eaters approach. Another way could be through her extensive knowledge of potions. She might create a potion that incapacitates or kills them when they come into contact with it.
A fanfiction involving Hermione and Death Eaters could focus on a moral dilemma. For example, if Hermione has the chance to save a Death Eater's life, would she do it? This could explore her character's sense of right and wrong. It could also be about how she endures the psychological torture that the Death Eaters might inflict on her, showing her strength and resilience.
Maybe Hermione discovers that one of the Death Eaters training her has a change of heart. This Death Eater then starts to help Hermione escape or undermine the other Death Eaters from within the group. It adds an interesting layer of complexity to the story.
One possible plotline could be a story of redemption. Maybe a Death Eater starts to question their beliefs after getting to know Hermione on a deeper level. For example, they could be forced to work together on a mission and gradually see the good in her, leading to a change in their ways.
One consequence could be that she is forced to perform dark magic against her will. This would be a huge moral struggle for her, as Hermione is a firm believer in the light side of magic. It could also change her perception of herself and her magic abilities in a very negative way.
One possible reason could be Hermione's intelligence. In the Harry Potter series, she is extremely smart, and the Death Eaters might be intrigued by someone with such powerful intellect in a fanfiction scenario. They could see her as a valuable asset or a challenging target.
Well, it could start with Hermione being kidnapped by the Death Eaters at a young age. She might be forced to attend their dark magic lessons. However, she uses her intelligence to learn about their weaknesses. For instance, she could discover a flaw in the security spells around their lair. And then, as she grows up, she could start to subtly manipulate the Death Eaters into fighting among themselves, all while pretending to be a loyal follower.
