In her estimation, in an attempt to protect the true Harry's identity, Snape sacrifices Hedwig, thus keeping the other
J.K. Rowling has stated before that she killed off Hedwig because her death was meant to represent the loss of innocence as Harry grew up and into adulthood (and stared down some Death Eaters). Her death happens during the Battle of Seven Potters in Deathly Hallows as the group is leaving Privet Drive.
Used it to sever the hand of a fellow Death Eater, who had been aiming at Remus Lupin's back during the Battle of the Seven Potters, but due to a slip, he accidentally cut off George's left ear instead, leaving him guilt-ridden.
In the book, Hedwig was killed as she sat in her cage by Harry's side – as she had so many times before – as they attempted to escape on the back of Hagrid's motorcycle. In the film, the scene was made even more heartbreaking, as Hedwig was killed while attempting to protect Harry from Death Eaters.
She and Harry were mad at each other before she died, and Harry was so distraught by it, and the poor thing screeched and fell to the bottom of the cage like a stuffed animal.
Many characters die in Harry Potter, but the series' most important deaths are arguably Lily and James Potter, Harry's parents. The couple perishes at Voldemort's hands, with Lily's sacrifice protecting Harry and tying his fate to the Dark Lord's.
Losing Sirius was far, far more devastating for Harry than watching Dumbledore be blasted from the tower. Sirius was the final remnant of Harry's family. He could tie him to his parents, but was full of life in a way that Remus never was. Sirius was more than a friend, or a mentor - he was a father, and brother.
In her estimation, in an attempt to protect the true Harry's identity, Snape sacrifices Hedwig, thus keeping the other Death Eaters off his scent albeit for only a short time.
In 1998, Fred participated in the Battle of Hogwarts, defending the castle's passageways with his twin. While fighting alongside his brother, Percy, he was killed in an explosion possibly caused by Death Eater Augustus Rookwood.
It is revealed that The Order of the Phoenix was betrayed by Kreacher, Sirius Black's house elf, when Sirius, in a fit of anger, gave Kreacher an order that permitted him to speak to Sirius' cousin, Narcissa Malfoy.
So Snape asked Voldemort to spare Lily. He basically rejected this request out of hand; killing the Potters was too important to him. He agreed to give Lily a chance to save herself, but he certainly didn't promise to save her life.
Harry's scar had hurt during Arrival Feast because of Quirrell's connection to Voldemort; Snape was then talking to Quirrell, allowing Voldemort, from the back of Quirrell's head, to sense Harry's presence.
Blood spurts from Draco's face and chest, and Myrtle beings screaming. Snape bursts into the room and heals Draco's wounds almost immediately. Snape hurries Draco to the hospital wing, commanding Harry to wait behind.
People know Hedwig is Harry's owl and she was attacked before, he might keep her in the cage so that she won't attacked or stolen by anyone(his enemies), until he got to somewhere safer.
"Hagrid is one of Voldemort's oldest associates, and knows his true identity" In Chamber of Secrets, it is revealed that Hagrid had been a student at Hogwarts during the same period that Tom Riddle (the true identity of Lord Voldemort) also frequented the school.
Both Lupin and Tonks die in combat, killed by Dolohov and Bellatrix Lestrange, respectively, leaving Teddy an orphan with Harry Potter as his godfather and Andromeda Tonks as his guardian. JK Rowling has since stated that she originally intended for both Lupin and Tonks to survive.
In the book, Fred's last lines are spent marveling over his estranged brother Percy joining them for the fight and cracking a joke. He's described as gleefully saying, "You actually are joking, Perce ... I don't think I've heard you joke since you were —" immediately before his death.
When Moody was killed by Lord Voldemort during the Battle of the Seven Potters, Harry was devastated by his death, as were the other Order of the Phoenix members.
Harry, returning to the school, looks into the Great Hall and sees Lupin and Tonks lying among the dead. While this is not mentioned in the book, the author has mentioned in an interview since its publication that Tonks was killed by her aunt Bellatrix Lestrange.
Rowling commented that "The moment Draco got what he thought he wanted, to become a Death Eater, and given a mission by Lord Voldemort, as he did in Harry Potter and the Half-Blood Prince, reality finally hit him" because his dream was "so very different".
The death eaters now quite effectively used the cruciatus and imperius curse as you might have seen, but why only rarely the avada kedavra curse? It's because it requires strength, powerful magical ability, to be able to use a curse of that magnitude and power, and that too repeatedly during a duel.
In order to preserve his position as a trusted Death Eater, Severus Snape was forced to tell Voldemort the true date at which the Order planned to move Harry.
The Rowling Library on Twitter: "Without Hermione, Harry would have died in book one.
It is explained that no funeral was ever held for Sirius Black because his body was never recovered. This presumably indicates that the body left the world of the living entirely when it fell through the veil.
