There could also be a plot where Harry is in a life - or - death situation. He has to use Avada Kedavra to protect his friends or loved ones from an even greater evil. However, this act changes him and the rest of the story is about him coming to terms with what he has done and trying to regain his moral compass.
One possible plotline could be an alternate universe where Harry is turned to the dark side early on. Maybe he discovers some false information about his parents' death and blames the wizarding world, leading him to use Avada Kedavra on those he believes are responsible.
In some fanfictions, Avada Kedavra is used as a way to explore the darker side of characters. For example, a character who was previously seen as good might be forced to use it in self - defense, which then causes them to struggle with guilt. It can also be used to create alternate universes where the spell has different effects or consequences.
In my opinion, it depends on how it's done. If the fanfiction is using Harry using Avada Kedavra in a context that is meant to shock and go against the core values of the series just for the sake of being edgy, then it's unethical. But if it's part of a well - thought - out exploration of the character's growth, for example, if Harry is corrupted by dark magic in an alternate universe, and the story is used to teach a lesson about the dangers of straying from one's values, it could be seen as a valid creative piece.
One ethical dilemma is when a 'good' character has to decide whether to use Avada Kedavra. In the original series, it's an unforgivable curse, but in fanfiction, authors might put their characters in situations where it seems like the only option. For example, to stop a powerful dark wizard who is about to kill many innocent people.
One interesting 'Harry Potter Avada Kedavra' fanfiction could be one where a character manages to reverse the effects of the Avada Kedavra curse through some ancient magic. In this type of fanfiction, it might explore the idea of life after being hit by the Killing Curse and how magic can be used in ways not previously thought of in the original series.
There is a fanfiction that explores what would happen if the Avada Kedavra curse was used on a magical creature instead of a human. It shows how the curse affects the creature differently and how the wizarding world has to deal with the consequences. It's full of interesting details about magical creature lore and the power of the curse.
Well, perhaps in the fanfiction, Draco Malfoy is researching a way to counter the Avada Kedavra. He could be secretly working with some of the more intelligent and magically inclined students at Hogwarts. They might be trying to find a protection spell that can block the Avada Kedavra. This could lead to a lot of sneaking around, secret meetings in the Room of Requirement, and tense moments when they think they're about to be discovered by the Death Eaters or other dark forces.
In the fanfiction, the grimoire might be the key to unlocking Harry's true potential. He could have been holding back in his magic all this time, and the grimoire shows him new ways of thinking about and using magic. It might also introduce him to a new group of magical creatures that he has to team up with to face a common enemy. This would not only expand the magical world in the fanfiction but also give Harry a whole new set of allies and challenges.
It could be an ancient heirloom from a long - lost wizarding family. Maybe it was passed down through generations and finally found its way to Harry.
He could be hit by a weakened or deflected version of the curse. Maybe someone tried to cast it on him but another spell interfered at the last moment. This could leave him with some strange side - effects, like temporary memory loss or a change in his magical abilities.
One possible plotline could be about the Weasley family trying to improve their financial situation. Maybe they come up with a new business idea in the wizarding world, like a magical product that becomes a huge success and changes their economic status. Another could be a story about how the Ministry of Magic regulates the financial system in the wizarding world, and there are some characters who try to manipulate or reform it.
