Well, it completely flips his character. Normally, Harry is seen as a hero who is kind - hearted and protective of his friends and the wizarding world. In this fanfiction, he becomes a much darker and more jaded character. His hatred for humans makes him more of an anti - hero or even a villain - like figure in some ways.
This idea completely alters the perception of the Harry Potter universe. In the original, Harry is at the center of a community of friends and allies. If he hates humans, that community is shattered. It also changes the way we view the magic world's relationship with the non - magical world. Harry was always a bridge between the two, but if he hates humans, that bridge is broken. It creates a much more fractured and less hopeful view of the entire Potterverse.
This type of fanfiction can also change the character interactions. Friends of Harry and Ginny may be forced to take sides or try to reconcile them. For instance, Hermione might be in the middle, trying to figure out what went wrong and how to fix it. It can make the story more about relationship drama rather than the typical Harry Potter adventures against dark forces.
It completely flips the usual narrative. In the original story, Harry has a sense of longing for his family, especially his parents. But in this fanfiction, the hatred changes the emotional core. It makes Harry a more complex and perhaps darker character. The relationships that were once sources of strength, like his connection to his parents through their sacrifices, now become sources of bitterness.
This type of fanfic might shift the focus from the fight against Voldemort to the internal conflict between Harry and Dumbledore. It could explore different character traits of both of them that were not as prominent in the original. For example, Harry's potential for anger and Dumbledore's more flawed side.
Well, it completely flips the script. Instead of being the hero, Harry is now a criminal. This changes the way we view the other characters too. For example, the relationship between Harry and Dumbledore might be seen in a different light. Dumbledore's guidance might be seen as either misguiding Harry into criminal behavior or as an attempt to control a potential criminal.
The relationships that Harry was supposed to form later in life, like his friendships with Ron and Hermione, would never happen. And the whole wizarding world would be different. Without Harry, there might not be someone to stand up to Voldemort in the same way. So, the power balance in the wizarding world would be completely shifted. Also, the mystery around Harry's scar and his connection to Voldemort would be left unresolved in a way that leaves the story with a sense of incompleteness.
It changes the story a great deal. Firstly, the gender change means different social expectations within the wizarding world. Female characters often face different challenges and opportunities. Also, being reborn as a Black alters the power dynamics. The Blacks are an old and influential family, so she has a different kind of influence and access to resources. For example, she may have more influence in Slytherin house which was often associated with the Blacks.
Well, it changes everything. Without Harry, there's no 'Chosen One' to fight Voldemort. So, Voldemort would likely rule the wizarding world unopposed. The Hogwarts School might become a place that only teaches dark magic or is completely under Voldemort's control.
One possible reason could be the betrayal he faced from some people in the wizarding world. For example, some students at Hogwarts might have spread false rumors about him or treated him unfairly because of his fame as 'The Boy Who Lived'. This could have led him to develop a general dislike for humans.
Well, it completely flips the relationship dynamic. In the original, Harry had a longing for his parents who were taken from him. But in this fanfiction, the hatred changes the emotional core. It makes the character more bitter and less of the hero we know from the original, who was motivated by love for his parents.
