The wizarding world would be thrown into chaos. Dumbledore's plans, whatever they were regarding Harry, would be completely disrupted. Groups like the Order of the Phoenix would be enraged. They might start a full - scale hunt for Vernon, and there would be a big debate about how to handle the situation with the Muggle authorities. Some wizards might even think that it's time to break the Statute of Secrecy and expose the Muggle world's role in Harry's death to the international wizarding community.
The wizarding world would likely be in shock. Harry is seen as a symbol of hope against Voldemort. His death at the hands of Vernon would be a huge blow. There would probably be a lot of anger towards the non - magical world for allowing such a thing to happen.
The wizarding world would be in shock. Harry is seen as a hero, and for him to kill Draco, even if Draco was from a 'less popular' side, would be a huge scandal. His friends like Hermione and Ron would be deeply conflicted. They would be torn between their loyalty to Harry and their disbelief at his actions.
The wizarding world's reaction would be complex. On one hand, Harry's friends like Hermione and Ron might be conflicted. They know the Dursleys were awful to Harry, but they also believe in the value of life. Wizards who have a strong sense of justice might understand Harry's actions, especially those who have also faced prejudice or abuse. But the more traditional and law - abiding members of the wizarding community would condemn Harry, and the Ministry would likely try to arrest him, leading to a possible conflict between those who support Harry and those who don't.
Some would be shocked and horrified. Fudge was a well - known figure in the wizarding world, and his sudden death at Harry's hands would be a big shock. There would be those who would immediately condemn Harry, believing that there must have been a non - violent way to deal with Fudge.
The reaction would also depend on how the events leading up to these actions were presented in the fanfiction. If it was made clear that Harry was acting in self - defense or to protect the wizarding world from a hidden threat, some might come to his side. But overall, it would create a huge upheaval in the wizarding world. The Ministry of Magic would be under pressure to take action, and there would be a lot of unrest among the students at Hogwarts who looked up to both Snape and Moody in different ways.
The wizarding world would be in chaos. Harry is seen as a hero and the 'Chosen One'. His death would leave a huge void. The Order of the Phoenix would be devastated and might seek revenge on Draco and those associated with him. Hogwarts would also be in turmoil, with students and teachers alike shocked and saddened. There would be a great deal of fear as well, as Voldemort's forces might see this as an opportunity to gain more power.
Many in the wizarding community would probably be very critical. Fanfic is often a passion project for fans, and Vernon's motives of just making money from it would be seen as wrong. They might organize to stop him from selling the fanfic. On the other hand, there could be a few who are curious about what a Muggle like Vernon thinks about Harry and the wizarding world through his fanfics, so they might buy them just to see what's inside, but still be ready to condemn his actions.
Some might be angry, thinking he's abandoning his responsibilities. The Ministry of Magic might try to persuade him to come back or even use force if they thought it was necessary for the safety of the wizarding world. His friends, on the other hand, would likely be sad and try to understand his reasons. They might also try to convince him to return, as they know how much he means to the fight against evil in the wizarding world.
They would be devastated. Harry has many friends and allies. People like Hermione and Ron would be heartbroken and would probably seek revenge. The Hogwarts faculty would also be deeply affected. Dumbledore, if he's still alive in the fanfiction, would feel a great sense of guilt for not protecting Harry better. There might be a split in the wizarding community, some believing the Dursleys were acting on their own, others suspecting a darker conspiracy.
There would be a great deal of shock and confusion. Many would start to question everything they had believed in. Families would be divided. Some might think that Harry had been corrupted by Voldemort's dark magic and try to find a way to reverse it. The Ministry of Magic would be in a panic. They would try to come up with new strategies to deal with this new threat. Teachers at Hogwarts would be worried about the safety of their students. And the Death Eaters, while initially happy to have Harry on their side, would also be suspicious of his motives and loyalty.
There would be shock and disbelief. The wizarding world has always seen Hogwarts as a symbol of hope, knowledge and safety. If Harry destroys it, many would be in denial at first, thinking it couldn't be true. Wizards and witches from all over would come to the ruins, trying to figure out what had happened.
