He could lose the trust of his friends. In the original series, his friends rely on him to be a force for good. If he starts using the Dark Arts, they would be horrified and might distance themselves from him. Also, he could be in danger of being corrupted by the dark power, which could change his personality and make him more like the villains he once fought against.
Well, there are several consequences. Firstly, he might lose his connection to the positive magical forces that have always supported him, like the magic of love and friendship. Secondly, the Ministry of Magic would likely come after him, as they are supposed to uphold the laws against the Dark Arts. And finally, he could lose his own sense of self. The Dark Arts are not just about casting spells; they are about embracing a dark and often cruel ideology. Harry using them could mean that he loses his identity as a defender of the light and a champion of good.
One possible consequence could be that he loses the trust of his friends. Ron and Hermione, who are firmly against the dark arts, might turn their backs on him. Another consequence could be that he is ostracized by the wizarding community. The Hogwarts faculty, who have always been on the side of good, would likely be very disappointed and may even try to stop him. And he could also attract the attention of the wrong kind of wizards, those who are into the dark arts themselves and might use him for their own purposes.
One possible consequence could be his expulsion from Hogwarts. Using black magic is strictly prohibited in the wizarding world, and the school has a zero - tolerance policy. Another consequence might be the loss of his friends. His friends, who uphold the values of good magic, might not be able to accept his use of black magic.
One example could be in a fanfic where Harry Potter is forced to use a dark spell to save his friends from an immediate and deadly threat. For instance, using the Imperius Curse on a Death Eater who is about to kill Hermione, but he struggles with the moral implications afterward.
One potential consequence could be a change in his relationships. His friends might be worried or even turn against him. For example, Hermione, who is always concerned about following the rules and doing what's right, would likely be very troubled. Another consequence could be a shift in his own moral compass. The dark arts are often associated with negative and unethical actions, so he could start to make more morally ambiguous decisions.
One possible consequence could be his estrangement from his friends. In the original Harry Potter world, his friends are firmly on the side of good. If he starts using dark rituals, they might not be able to understand or accept his actions. Another consequence could be a corruption of his own soul, as dark magic is often depicted as having a corrupting influence in the series.
One possible consequence is that the wizarding world would be in a state of confusion. The traditional boundaries between good and bad would be blurred, and many wizards might not know how to react. Some might fear Harry's new - found power over the Dark.
Well, if Ginny uses love potions on Harry in fanfiction, it might create chaos among their friends. Their friends, like Hermione, might sense that something is off with Harry's behavior and start investigating. This could lead to a big conflict within their friend group, as some might side with Ginny thinking she did it out of love, while others would be appalled by her using such unethical means.
There could be some negative consequences too. Maybe the dragon had some kind of magical protection or was under the care of a powerful wizard or creature. Harry might then face the wrath of those who were protecting the dragon, leading to him having to go into hiding or facing dangerous challenges. Also, the act of killing a dragon, even in self - defense, might make some more sensitive wizards view him in a different, less favorable light.
One possible consequence is that the wizarding world might see Harry as a hero even more than before. After all, dementors are very dangerous creatures, and if he manages to destroy them, it's a huge accomplishment.
It could be an ancient heirloom from a long - lost wizarding family. Maybe it was passed down through generations and finally found its way to Harry.
