It could be a reaction to the intense relationship between Edward and Bella in the original. Maybe the writer wants to explore the consequences of a broken or twisted relationship. Also, in the world of fanfiction, there are no real boundaries, so some might be drawn to creating a very controversial and dark scenario like this just for the sake of creativity and to see how far they can push the characters.
Some fans might create such a disturbing fanfiction as a form of extreme dark - themed exploration. They may want to break away from the typical love - story - esque nature of the 'Twilight' series and create something that shocks and stands out.
Perhaps the writer has a different interpretation of the characters. They might see Edward as having a darker side that could be pushed to the extreme under certain circumstances, like in a situation involving a baby. It could also be a way to comment on the sometimes - obsessive nature of the relationships in the 'Twilight' series, by taking it to a very dark and unexpected place.
Perhaps it's related to his internal conflict regarding his relationship with Bella. He might be feeling so much guilt about bringing her into the dangerous vampire world that he has a moment of self - destructive behavior where he almost kills her. Or it could be a plot device used by the author to create more drama and tension in the story, making the readers more engaged as they wonder how Bella will survive and how their relationship will recover from such a traumatic event.
I'm not aware of any official 'Edward Kills Bella' baby fanfiction. In the original 'Twilight' series, their relationship is complex but not of this extreme nature. Fanfiction can vary widely in themes, but this seems like a very dark and uncharacteristic take compared to the source material.
One reason could be a shift in the story's setting. If the fanfiction is set in a different time or place, Bella's values and interests might change, leading her to not like Edward. For instance, if it's a modern - day setting with different social norms, she may find Edward's old - fashioned ways off - putting.
Perhaps she has her own vision of their relationship and doesn't want it to be influenced by the often - strange and varying ideas in fanfiction. Fanfiction can be full of outlandish concepts that she doesn't want to be part of. She wants to preserve the unique and special nature of her relationship with Edward as it is in real life.
Another reason might be Edward's overprotectiveness. He could have made a decision for Bella without consulting her first, like preventing her from seeing a friend. This kind of controlling behavior could make Bella feel frustrated and end up in tears.
One possible reason could be to create shock value. Writers might want to break the expectations of readers who are familiar with the loving relationship between Edward and Renesmee in the original 'Twilight' story. By creating such a dark and unexpected scenario, they hope to grab the attention of readers who are looking for something different from the usual fanfiction.
Another reason might be that the fanfiction is set in an alternate universe where their relationship has some fundamental differences. For instance, if the vampire - human dynamic is changed in that particular fanfiction, Bella might avoid Edward because she is afraid of the new and unknown aspects of their relationship.
One possible reason could be that some fans want to explore a different dynamic. In the original story, Edward and Bella are in love, but in this fanfiction, perhaps the writer wants to show a more complex relationship where Edward hates Bella. Maybe it's to add more drama or to explore an alternative storyline that goes against the typical romance.
Perhaps there are some who have a darker side to their creativity and don't fully consider the implications of writing about abuse. But this kind of fanfiction should not be encouraged as it goes against the positive nature that most fanfiction communities strive for.
Some writers might create 'Edward is abusive to Bella' fanfiction to explore the darker side of human nature and relationships. They want to see how the story would unfold if the relationship had a negative turn.
