It starts with her being in a difficult situation and being lured into the Death Eater world.

The author does a great job of showing the internal conflict within Bella.
I'm not sure about a specific 'Bella is a Death Eater' fanfiction that stands out above all others. However, you can try searching on fanfiction - specific websites. Look for ones with high ratings and positive reviews. Usually, those are the ones that handle the concept well, whether it's the character development of Bella as a Death Eater or the overall plot within the Death Eater - centric world.

In 'bella is a pureblood and death eater' fanfiction, the theme of identity is prevalent. As a pureblood in the Death Eater circle, she has to constantly reaffirm her identity. Is she just a tool of the Dark Lord? Or does she have her own motives? Also, the theme of secrecy and betrayal often comes up. She may have to keep secrets from her family or face betrayal from her fellow Death Eaters due to her pureblood status.
There are several. Some focus on Snape's early days as a Death Eater. For example, in one fanfic, it details how he was recruited, his initial thoughts on Voldemort's ideology, and how he gradually started to question it. It also shows how his relationships with his fellow Death Eaters were formed and evolved over time.
Power is a common theme. When Bella is a Death Eater, she often has to deal with the power dynamics within the group. Another theme is the loss of innocence. She has to let go of her previous self - concepts and embrace the dark and often cruel world of the Death Eaters.
Bellatrix Lestrange is also a likely candidate. Her encounter with Hermione would be extremely intense. Given her loyalty to Voldemort and her rather unhinged nature, she would likely pose a serious threat to Hermione, but Hermione might also find a way to use Bellatrix's madness against her.
One popular 'a death eater and a mudblood fanfiction' could be 'Forbidden Alliances'. It delves into the complex relationship between a reformed Death Eater and a Muggle - born witch. The story shows their struggle against the prejudices of the wizarding world.
Bellatrix Lestrange's younger brother or some other minor Death Eater character could be used. This would allow for the creation of a new character with his own motives and backstory. He could be betrothed to Hermione as part of a larger plot by Voldemort to gain control over Hermione's knowledge and magic. This would put Hermione in a very difficult position as she would be tied to a very dark and dangerous family.
There's also a possibility that it could be a minor Death Eater that we don't know much about from the original series. The author of the fanfiction could create a new character who was a Death Eater but is now having doubts. Hermione could be the one to find this person and start their journey of change. This would give the author a lot of creative freedom to develop the character's backstory and their relationship with Hermione.
Sure. When searching for such fanfiction, it's important to read reviews if available. A well - written 'Death Eater Stalks Hermione' fanfic could add new dimensions to the Harry Potter universe.

First, create a unique and complex original character (OC). Think about their backstory, like what led them to become a Death Eater. Maybe they had a difficult family life or were influenced by a powerful dark wizard. Second, understand the world of Death Eaters in the Harry Potter universe. Know their beliefs, their hierarchy, and how they operate. Third, focus on the character's internal conflict. Even as a Death Eater, they might have doubts or a moral compass that still tugs at them. This can make the character more interesting and the fanfiction more engaging.
