Specifically, Draco was jealous of Harry. It was easy to miss because Draco didn't often show his emotions, modelling himself on his cold, confident, calculating father, but J.K. Rowling has confirmed that a lot of his enmity towards Harry stemmed from envy.
Malfoy hated all the attention Harry recieved . Malfoy thought Harry was a dark wizard, he tried to befriend Harry but he refused because of the way Malfoy treated Ron whom he already made friends with. That's why Malfoy hate Harry for turning him down.
According to Rowling, Malfoy originally makes an effort to be Harry's friend because "it will be cool to turn up at the school being Harry Potter's friend, because Harry is so famous." However, Harry did not want Malfoy as a friend because he "has been so rude about Rubeus Hagrid and about Ron, who Harry likes so much" ...
“Harry was constantly crushing on Draco. He just couldn't hide it.” In the books and movies, Harry and Draco are constantly at each other's throats, given that Draco's parents are Voldemort supporters and the evil wizard killed Harry's parents.
Narcissa may have been many things; she was cruel and distant and happy to watch her family return to Lord Voldemort's side as he rose again, but she was also self-sacrificing; she loved her son and her husband and she thought nothing of putting herself in danger to protect them.
Narcissa Malfoy's Very Dangerous Lie
But she was also a mother, which meant she was willing to risk everything to make sure her son was safe. When Harry survived Voldemort's Killing Curse for the second time, Narcissa pretended he was dead so she could get to Draco.
She didn't know if he was alive or dead. Being the mother she is, first and foremost, she no longer cared if Voldemort won or lost. All she cared about was knowing if her son was alive or not. So she bent down and when she felt a pulse, she whispered to Harry to ask him if Malfoy was alive.
9 Times Harry Kissed Draco and the 1 Time Draco Kissed Harry.
Malfoy spots Harry and casts a Cruciatus curse; Harry, defending himself, using the Half-Blood Prince's Sectumsempra spell without knowing its effects. To his horror, it gashes Draco's face and chest, spilling his blood everywhere.
I think Draco was overwhelmed both with Katie's death and the fact that he was forced to be the one to kill Dumbledore as a way of Voldy punishing his family due to his beef with Lucius.
Draco had several reasons for lying to Bellatrix, including the fact that he was never a bad person. Moreover, he no longer found working for the Dark Lord appealing and hated how Voldemort treated his family. He did not intend to harm anyone and believed Harry was the only person capable of defeating Voldemort.
Harry, however, had never been less interested in Quidditch; he was rapidly becoming obsessed with Draco Malfoy.
Finally, Lucius, Narcissa, and Draco never fled Hogwarts with the other antagonists and losers. In The Deathly Hallows novel, the Malfoys defect from Voldemort's army, betraying the other Death Eaters.
Despite being a valued Death Eater in the days before Voldemort fell following his attack on baby Harry, Lucius stumbled out of favor with the Dark Lord when he squandered Riddle's diary (secretly a horcrux) in Chamber of Secrets and failed to obtain the prophecy in Order of the Phoenix.
Voldemort had waged psychological warfare on the Malfoys, and knowing that he held total power over them- he fully took advantage of his situation. He wielded his power to the point that they no longer wanted to follow him- but they were in too deep.
Lucius Malfoy had a strong dislike of Albus Dumbledore. This is due to two reasons – Dumbledore believed in Muggle rights which contradicted Malfoy's pure blood beliefs. In addition, Lucius was a Death Eater, so he believed that Lord Voldemort was a much more powerful wizard than Dumbledore.
Voldemort hugged Draco as an improvisation and it wasn't planned. Even Tom Felton (Draco Malfoy) was caught unaware which increased the effect. In Harry Potter style, it was like a welcome for Draco, but as Voldemort had never known love, he didn't know how to hug him very well. Thats why they had the awkward hug.
It turns out that instead of rejoining the Death Eaters, Draco was supposed to help Harry at the very last second by throwing him his wand to help him defeat Lord Voldemort.
He knew all too well what would happen to Harry and his friends if they were handed over, yet his parents would be proud and grateful beyond measure. Draco was torn between loyalty to his family, fear of Voldemort and worry for his former classmates.
Pansy Parkinson
Draco lost his virginity to her on the Yule Ball night in fourth year and since then Draco and Pansy had been sexual partners.
In a recent interview, J.K. Rowling said that Draco had strong positive feelings for Hermoine, and would always have "lingering" feelings. However, due to his upbringing, he was unable to act on those feelings, and instead made fun of her, gaining some attention that way.
While Fiennes kept cast members on their toes by changing who he would address as Voldemort in the scene, the encounter with Draco was always planned. However, the hug was not scripted and something Fiennes only did on a single take.
Since Harry was so young when his parents died, he has no memory of them (or their deaths) and relies on information from other people in his life. Unfortunately for Harry, he was raised by his Aunt Petunia (Lily's sister) and Uncle Vernon Dursley….
“Is Draco alive? Is he in the castle?” The whisper was barely audible; her lips were an inch from his ear, her head bent so low that her long hair shielded his face from the onlookers.
Voldemort intentionally made six Horcruxes, but when he used Avada Kedavra on Harry, he unintentionally created a seventh Horcrux. Instead of dying, Lily's love for Harry created a counter 'curse' known as Sacrificial Protection and saved Harry.
