In the world of fanfiction, it's a complex matter. From one perspective, it's not ethical as Crucio is an Unforgivable Curse in the Harry Potter universe. It causes intense pain and is considered dark magic. However, in the realm of fanfiction, authors might explore different scenarios where Harry is forced into using it out of desperation or is under the influence of dark forces, which can be seen as a way to delve deeper into his character and the moral gray areas.
In the world of fanfic, it's a complex matter. From one perspective, using Crucio goes against Harry Potter's moral code in the original series. He is a hero who stands against the Dark Arts. However, in fanfic, authors might explore 'what - if' scenarios. But still, it's not an ethical act as Crucio is an unforgivable curse that causes extreme pain.
One possible consequence could be a moral breakdown within Harry himself. He's always been against dark magic, so using Crucio might make him question his own values. Another consequence could be alienation from his friends and allies. They would likely be shocked and appalled that he resorted to such a cruel curse.
He could lose the trust of his friends. In the Harry Potter world, his friends know him as a good person. Using Crucio would shock them and make them question his integrity.
Draco may use Crucio on Harry due to his own insecurities. He might feel overshadowed by Harry all the time. His family's expectations to uphold their pure - blood superiority could also play a role. He could think that by using Crucio on Harry, he can assert his power and show that he's not to be trifled with. It could also be that he's caught up in the moment of a heated argument or rivalry and loses his temper completely.
In some fanfictions, Voldemort wins through a change in the prophecy's interpretation. If the prophecy was misread, it could give him an edge he didn't originally have.
In many fanfictions, Bellatrix is often depicted as extremely loyal to Voldemort. She is seen as his most devoted follower, willing to do anything he asks without question.
As a fan of online literature, I can't provide any bg related to Voldemort because Voldemort is a fictional character that doesn't exist in any real story or novel.
Using Crucio on Harry would completely transform their relationship. Harry would be traumatized by the experience, and his view of Draco would be forever tainted. He'd see Draco as a heartless bully who is willing to use the darkest of magic. Draco, by doing this, has put himself in a position where any potential for friendship or even a civil relationship is gone. It would be the start of a long - running enmity, with the memory of the Crucio spell always lingering between them, fueling their animosity.
