I don't know why, but I took Fred's death the hardest. I even had to put the book for a while because of how much I was crying.
Dobby and Dumbledore both got a lot of tears. Fred is after them for amount of tears.. I am a crier though
Dobby's death was definetly the most saddening. then Dumbledore, then Fred.
I think I cried the most when Dobby died, but probably just as much when Fred, Lupin & Tonks died. maybe even Hedwig! <3
When I read the book Dumbledore's death had me in tears, although his movie death was done terribly and only made me crack up. In the movie, Dobby's death jerked some tears. Sirius makes me upset, but only when I think about how lost and angry Harry becomes as a result of it.
I don't cry too incredibly easy, but Dobby certainly pushed me over the edge. That was the first and only time reading through them (the first time, at least) that I actually cried. Fred's death, though quick, makes me tear up, too.
The rest big deaths in the last book, where pretty much everyone died, hppened so fast. Which was understandable, I guess, it was a WAR, things happen... quickly.
As for Cedric, well, he was TOO nice.
But I have recently had a Weasley twins obsession, and the next time I read that chapter with Fred, accio Kleenex, I'll need them.
Its a tie for me between Sirius and Snape. Sirius was (and is) my favorite marauder, and it was really hard for me when he died. I cried forever. As for Snape I had suspicions from the first book that his character would have this tragic end. I cried and cried when he died in the book. There are still tear stains on the page.
It's always the death of side characters (more or less) that are saddest to me.
When Cedric Diggory died, I lost it. Like, "crying for hours on end" lost it. I'm not even sure why, either. Fred's death was totally life-ruining. But when Tonks and Remus died, I was destroyed. Demolished. Never to be happy again. It emotionally damaged my ten-year-old heart beyond belief.
The death of Dumbledore messed me up, too, though. At that point, I wanted to smash Snape's face in.
And then this morning I saw a car with the license plate number thing "HEDWIG" and I burst into tears.
I would have to say Tonks (in the book, of course). I just felt like it was comepletely pointless. I mean, she wasn't even there when all the dead people were talking to Harry before he went into the forest, and it left Teddy an orphan. I loved Tonks.
R.I.P. Nymphadora. :'(
Also, Fred's was probably the most heartbreakingly written death.
It's between Dobby (I was in such a state it was ridiculous) and Tonks and Lupin. I just kept thinking that their kid wouldn't have parents and it was really sad :(
