If the Disney version of Snow White had what these days we call “agency” — if she were making things happen rather than having trouble or good fortune fall into her path — she would be the villain.
She terrifies the Queen, because (as the Mirror says) she will inevitably usurp the Queen’s status.
She stops the Huntsman from killing her, which makes him run off, presumably far from where the Queen can find him — and far from any home or family he might have.
She takes over the Dwarfs’ home and way of life, bending it to her needs and wishes.
And the way she treats the Prince — well, I wonder if her idea of “happily ever after” matches his.
