One motivation could be love. Maybe he has fallen in love with a non - Death Eater, like a Gryffindor girl, and doesn't want to be part of the dark side. Another could be fear of the consequences. He might have seen what the Dark Mark has done to others, like how it controls them, and he doesn't want that for himself.
Well, Draco could be motivated by a sense of self - preservation that goes against the Death Eaters. He might realize that joining Voldemort is a losing battle. Also, he could have a moral awakening. He has seen the atrocities committed by the Death Eaters and decides he doesn't want to be associated with that evil. And perhaps he has a secret admiration for the Order of the Phoenix and their fight for good, which makes him refuse the Dark Mark.
In fanfiction, Draco might refuse the Dark Mark because he wants to break free from his family's expectations. He's tired of being pushed into the role of a Death Eater just because of his family name. He could also be influenced by new friendships. For instance, if he has made friends with students from other houses who have different values, they could convince him that there's a better way than following Voldemort. Additionally, he might have witnessed a particular act of kindness from the good side that makes him question the Dark Mark and the Death Eaters' ideology.
One reason could be his underlying sense of good. Despite his family's alignment with the Dark side, Draco might have a moral compass that rebels against the evil associated with the Dark Mark. He may have seen the destruction and pain it causes and doesn't want to be part of it.
In fanfiction, Draco's connection to the Dark Mark often serves as a source of internal conflict. Writers explore how he grapples with the mark's implications and his family's ties to the Dark side. It can be a powerful device to show his character development.
The Death Eaters would probably see him as a traitor. They might try to hunt him down and punish him severely, perhaps even kill him. He would constantly be in danger and have to be on the run.
In some fanfictions, Draco's Dark Mark is shown as a constant source of pain, both physical and emotional. It's a reminder of his family's allegiance and his own mistakes.
One possible scenario could be that Draco realizes the true evil of Voldemort and the Dark Mark represents everything he doesn't want to be. He might see Hermione's strength in the face of the Dark side and be inspired by her. Maybe he secretly helps the Order of the Phoenix instead of joining the Death Eaters, all while falling in love with Hermione.
One plot idea could be that Draco discovers Hermione has a connection to the Dark Mark against her will. Maybe she was cursed with it during an encounter with Death Eaters. Draco, having some knowledge of the Dark Arts, decides to help her get rid of it secretly, which would lead to many tense and secretive meetings between them as they try to figure out how to break the curse without getting caught by either side.
In fanfiction, when Draco refuses the Dark Mark, it completely alters his relationship with his father, Lucius. Lucius, being a devout Death Eater, would be furious and might even try to force Draco into it. This family drama would add a lot of depth to the story. Also, Draco's refusal could have a ripple effect on Hogwarts. Slytherin house would be divided, with some students seeing Draco as a traitor and others respecting his choice. This could lead to some interesting power struggles within the house, and potentially new friendships and rivalries across different houses.
Perhaps Draco is tired of living in his father's shadow. His father has always been a dominant figure in his life, and by killing him, Draco could be trying to assert his own identity.
Well, if Harry has the Dark Mark in fanfiction, it would completely change his relationship with the wizarding world. He'd likely be seen as a threat and be shunned. His friends might turn against him out of fear or be forced to by the Ministry. It would also make his fight against Voldemort much more complex as he'd be associated with the Death Eaters.
In some fanfictions where Draco kidnaps Hermione, his motivation could be related to family pride. The Malfoy family has long - held grudges against the 'Muggle - born' status that Hermione represents in the wizarding world. He might see kidnapping her as a way to assert the superiority of pure - blood wizards. Another possible motivation could be jealousy. Draco may be jealous of Hermione's intelligence and close relationships with Harry and Ron. By kidnapping her, he could try to break those bonds and prove himself more powerful.
