What JKR thought while writing Harry Potter:
Oh, James and Lily are a flawless couple? Hm...I'll kill them.
Oh, Harry is happy with Sirius as a father figure? Let's kill him.
Oh, Dumbledore has been Harry's mentor since he was 11? Haha, lol, let's kill him.
Oh, Remus is happy for the first time since James and Lily died? Kill him.
Oh, Tonks is happy and has a child at home? Okay, she's DEFINITELY dying.
Oh, Dobby is finally free and happy? He doesn't deserve it. Die, Dobby, die.
Oh, everyone loves Fred? I'll kill him and drink their tears.
Oh, Snape is possibly one of the greatest characters in the book? LOL! DEAD
