What does the governess' reaction to the appearance of Quint and Miss Jessel reveal about her as a character?

The governess may be a loving, strong woman, whose struggle against the evil ghosts she encounters for the souls of the children in her care show her to be a good person. Or she may be mad - sexually repressed and delusional, imagining ghosts and evil that is not there - responsible for the destruction of young Flora and Miles. This really depends on your perspective.
