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.
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.
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.
