I wondered if somehow her characters grew out of her determined
story-ending, if that is possible. So that the end of the story that
she had fixed from the beginning didn't fit anymore.

Ceridwen:
Welcome, Les!  Your post was understandable.

I think you're right about the characters growing away from the story 
ending Rowling wrote as she began to write the series.  If you have 
ever tried to write a story or a fan fiction, you'll see that 
sometimes, characters disagree with your idea of a story.  Rowling 
said this has happened to her: one character who was supposed to have 
died, Arthur Weasley in OotP, did not die.  Two characters who were 
supposed to live, died instead.  It was the story, or the characters, 
dictating the change.

Another point about the characters, and the plot, too, growing away 
from the original story ending is that Rowling was new at writing 
when she originally wrote the ending.  Her skills improved as she 
wrote each book.  When she went back to the original ending, with the 
changes for who lived and who died, the difference between the young, 
new writer she once was, and the experienced and successful writer 
she became, was very obvious.  Perhaps, to her, the ending still made 
a lot of sense.  I think the story, the characters, and the direction 
the books took, should have meant a new ending, written with her 
improved skill, and using the more nuanced plots that deveoloped over 
the series.
