Naw, it's no accident of Freddy gettin killed. The first telling of the backstory is by Nancy's mother in the basement of the original Pt 1, the neigborhood parents of Elm St. gather together and kill Freddy for killing their children. That's far more scary than actually seeing the backstory in film like they did in part 6 and now this new remake.
I agree it would be bad if they made Freddy sympathetic. When some parts of a movie are left up to the viewer's imagination, it's more intriguing and deep.
