In the 'Harry joins the Death Eaters fanfiction', it could be that there is a prophecy that Harry misinterprets. He believes that he is fated to be part of the Death Eaters in order to change the wizarding world for the better. So he goes against his friends' advice and joins. However, as he gets involved with them, he realizes the true horror of their actions and has to find a way to break free without getting killed or turning completely evil.
Well, perhaps in this fanfiction, there's a big misunderstanding. Harry might think that by infiltrating the Death Eaters as one of them, he can actually bring them down from the inside. So he pretends to join them, but things get out of hand as he has to constantly prove his loyalty to the dark side, which is really difficult for him.
Well, one possibility could be that he is forced to join them under some kind of dark magic threat. Maybe Voldemort has found a way to control his mind and he has no choice but to follow their orders. This would lead to a lot of internal conflict for Harry as he struggles with his own values.
A possible motive could be self - preservation. If they believe that Voldemort's downfall is inevitable and that by saving Harry, they can gain some form of leniency from the side that opposes Voldemort. They might think that Harry has enough influence to spare their lives if they help him.
Well, if we look at 'Harry Joins Death Eaters Fanfic', it could lead to a whole new set of storylines. Harry might be lured in by the power the Death Eaters seem to have. He could start using dark magic, and his moral compass would be all messed up. Maybe he'd be used by Voldemort to infiltrate the Order of the Phoenix from the inside. It would be a very different Harry, one who has lost his way and is now on the side of evil.
In a 'Harry kills all Death Eaters' fanfiction, the plot could start with Harry getting fed up with the constant threat the Death Eaters pose. He could go on a solo mission to hunt them down one by one. Along the way, he might face some moral dilemmas as he realizes that some Death Eaters might have families or could potentially be redeemed. But in the end, he decides that the only way to ensure peace is to eliminate them all. This could lead to a series of intense battles in different wizarding locations, and Harry could gain new allies or use some unexpected magical artifacts to achieve his goal.
Perhaps in the fanfiction, Hermione has something that the Death Eaters are after, like a powerful magical artifact. They fight over who gets to take her prisoner first in order to extract the location of this artifact from her. It could also be that they are under the orders of Voldemort to capture her alive, but they start fighting among themselves due to personal rivalries and the desire for glory within the Death Eater ranks.
If Hermione joined the Death Eaters in fanfiction, it would completely turn the original plot on its head. The Death Eaters are known for their dark magic and prejudice, which is the opposite of Hermione's values. This could lead to a very different kind of story, perhaps one where she tries to change the Death Eaters from the inside, or she could be a double agent. It would be a very dark and complex alternate universe.
Maybe the Death Eaters save Harry, but then they try to use him as a bargaining chip. They think they can trade Harry's safety for something they want, like amnesty or a powerful magical artifact. However, things don't go as planned and they end up having to truly protect him.
Well, one possibility could be that Harry stumbles upon Fleur while she's being cornered by Death Eaters during a battle. He quickly uses a powerful disarming spell to take out the first Death Eater's wand. Then, he creates a diversion using a Patronus to confuse the rest and whisks Fleur away to safety.
One possibility is that some Death Eaters might have a change of heart. Maybe they see the true evil of Voldemort's cause. For example, a Death Eater who has a family member saved by Harry could decide to help. They could secretly pass on information about Voldemort's plans to Harry. In the complex world of the Harry Potter universe, personal motives and moral awakenings can be strong forces.
Maybe he would be trained to be a super - powerful dark wizard. However, his natural good - heartedness, which he got from his parents, starts to shine through. This could lead to a conflict within the Death Eater community. He might be seen as a threat to their ideology and have to fight for his life against those who raised him.
