JK Rowling reveals why Dursleys hated Harry so much in the latest Pottermore post
Happy Birthday JK Rowling! 3 times she was badass and fought for rightsReuters

No "Harry Potter" fan can ever get over the tragic death of Fred Weasley, who died while battling Death Eaters outside the Room of Requirement in "Harry Potter and the Deathly Hallows: Part 2". However, no one will mourn Fred more than his creator JK Rowling. 

On 2 May, which marked the 17th anniversary of the 'Battle of Hogwarts', author Rowling tweeted her apology: "Today I would just like to say: I'm really sorry about Fred. *Bows head in acceptance of your reasonable ire*".

She clarified that though she had to kill many beloved characters such as half-blood witch Tonks and the werewolf teacher Remus Lupin, Fred was her first and his death was the most difficult one for her to write. "I thought I might apologise for one death per anniversary. Fred was the worst for me, so I started with him," Rowling tweeted.

Fred Weasley was one half of the adorably hilarious twins Fred and George. Like his twin, he was a born prankster and inventor; the duo dropped out of Hogwarts shortly before graduation to start a successful joke shop in Diagon Alley, named Weasleys' Wizard Wheezes.

He fought with Harry Potter and the rest of the Weasleys against the invasion of Death Eaters and was killed while fighting next to his brother Percy, outside the Room of Requirement. He has a namesake in the first son of his twin brother George.

Rowling has earlier said she always knew he would have to die in the book, but that she thought fans would have expected George to die first because he was gentler and hence, more vulnerable of the duo.
