It's not entirely unethical. Fanfic is a form of creative expression. If the writer is using the 'Hermione tortured' concept to make a point about the character's growth, like how she overcomes such a traumatic experience, it can be seen as valid. But if it's just for shock value or to be mean - spirited towards the character, then it's not so ethical.
I think it depends on how it's done. If it's written in a way that is more about exploring the psychological impact and the resilience of the character, and not just for shock value, it could be considered a valid form of fan - created content. But if it's gratuitous torture with no real purpose other than to be cruel, then it's not ethical. We should respect the integrity of the character and the feelings of the fans who care about her.
A frequent theme is the exploration of Hermione's emotional state during and after the torture. It might also involve themes of revenge, where she or her friends seek retribution against those who tortured her. Additionally, some fanfics might focus on the magical and physical consequences of the torture on her body and mind.
Hermione herself could be more vigilant. If she noticed any signs of danger or people acting strangely around her, she could take precautions. She could use her own intelligence and magic to create defenses. For instance, she could set up a spell that alerts her when someone with malicious intent is near, and then she could either escape or fight back.
I'm not a big fan of such dark fanfictions, but you could try looking on fanfiction.net. They have a large collection of Harry Potter fanfictions, and you might be able to find one with that plot there.
If Hermione is pregnant in a fanfic with Narcissa, it would be a very unique relationship. Narcissa has a complex character. She has been part of the Death Eaters' families but also showed some redeeming qualities. Hermione, on the other hand, is a strong - willed and intelligent witch. Their relationship could be based on a mutual attraction that defies the norms of the wizarding world. The pregnancy could be a turning point in their relationship, making them more determined to be together despite the potential backlash.
One alternative could be exploring her dealing with difficult moral dilemmas. For example, she might have to make a choice between saving a friend or following a strict rule. This would add depth to her character without involving torture. Another option is to have her face her fears in a more psychological way, like dealing with the fear of failure or not being good enough. It can create tension and a darker mood without being overly cruel.
This is a rather interesting and unique fanfic concept. In the world of fanfiction, the idea of Hermione being pregnant with werewolf pups could lead to a lot of different plotlines. It could explore the challenges she would face in a world that might be prejudiced against werewolves and her relationship with the werewolf father. However, it also needs to be handled carefully to avoid going against the core values of the original series.
One common theme is the exploration of Hermione's character development during pregnancy. Another is her relationship with Ron or other characters like Harry as she goes through this new phase.
A fanfiction titled 'Hermione's Torment' is worth checking out. It begins with Hermione being captured and tortured in a secret location. The writer describes her pain and struggle vividly. Additionally, 'Shadow of Torture on Hermione' presents a complex plot where Hermione is not only tortured but also has to deal with betrayals within the wizarding community while trying to find a way to free herself.
