The Hogwarts students would be especially confused and heartbroken. Harry was their hero, and his joining Voldemort would shatter their beliefs. Teachers like Dumbledore (if still alive in the fanfiction) would be deeply disappointed but would also try to understand what led Harry to this path, and they would search for a way to bring him back to the side of good, while also preparing for the worst - case scenario of a united Voldemort - Harry front against the wizarding world.
The Death Eaters would initially be overjoyed. They would think that with Harry on their side, they are invincible. But some of them might also be suspicious of Harry's motives, fearing that he is a double - agent. As for the general wizarding population, they would be terrified. Harry was seen as their hope, and now that he has joined Voldemort, they would feel completely hopeless and defenseless.
The wizarding world would be in shock. People who once saw Harry as their savior would feel betrayed.

Hogwarts would also be in turmoil, with students and teachers alike not believing that Harry could turn to the dark side.
The wizarding world would be in chaos. The Order of the Phoenix would be extremely worried and likely try to rescue Harry. The Death Eaters, on the other hand, might see it as a sign of Voldemort's power and dominance. Hogwarts would also be affected, with teachers and students fearing for the future of the wizarding world.
Well, the pure - blood families who were on the fence about Harry might finally accept him wholeheartedly. They would see that he was the one who could truly rid the wizarding world of Voldemort. However, there would also be those who would be critical. Some of the more traditional wizards and witches might think that using a shooting method was too violent and un - wizard - like. They might worry that this sets a bad precedent for future conflicts in the wizarding world. But overall, the general public would be relieved that Voldemort was finally gone and would likely celebrate Harry as a savior.
There would be a great deal of shock and confusion. Many would start to question everything they had believed in. Families would be divided.

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.
The wizarding world would likely be in an uproar. Many would see it as a betrayal of all that Harry stands for. After all, he's the hero who defeated Voldemort. Others might be intrigued by the idea, seeing it as a way to explore the complex relationship between the two. Some might worry that it gives Voldemort too much credit or glorifies him in some way.
The Order of the Phoenix would be horrified. They have spent so much time and effort fighting against Voldemort. If they found out Harry had asked for his help, they would likely feel betrayed. They might even try to stop Harry, thinking he had been somehow influenced or corrupted.
The wizarding world would be in shock. Harry is seen as their last hope, so his surrender would make many lose faith. The Order of the Phoenix might go into a state of chaos, trying to figure out how to rescue Harry and continue the fight against Voldemort without him.
The wizarding world would be in shock. Harry has always been seen as a symbol of hope and the one who could defeat Voldemort (Tom). People would feel betrayed, especially his friends like Hermione and Ron. The Ministry of Magic would likely see Harry as a new threat and start devising plans to stop him. There would be a lot of fear and uncertainty among the wizarding population.

Ron might be more conflicted, his loyalty to Harry warring with his fear of Voldemort. The Weasley family would be divided in their opinions. Some might still support Harry, while others would be hesitant. Dumbledore's portrait, if it could, would likely offer some cryptic advice. And the Death Eaters? They might see Harry as a potential ally or a threat, depending on how they view Voldemort's paternity.
The wizarding world would likely be plunged into a state of despair. Harry was seen as the 'Chosen One' to defeat Voldemort, so without him, there would be a sense of hopelessness. Voldemort would probably have free rein to impose his dark rule without much opposition at first.
