Nina, the ballerina in the Black Swan, believes that people who attempt or threaten to interfere with her distorted thinking are dangerous to herself and her goals. She is as merciless with them as she is with herself.

She doesn’t perceive the emotional consequences to others her behavior causes. If she gets a glimmer of pain she causes in others she will justify it to herself by saying she had no choice. And indeed, to her eating-disordered mind, she didn’t have a choice.

For Nina, the obsessed ballerina of the Black Swan, to get help in establishing her healthy process of development she would have to:

In The Black Swan, Nina’s distorted perceptions based on fantasies and limited vision become hallucinations she believes. Brain cells deprived of nutrition do not function normally. Nina believes perceptions that take her deeper into her hallucinations and guide her behavior.

The end of the film shows the extremes of glorified and malignant romanticism based on the unrealistic definition of personal perfection. Nina glorifies meaningless death and destruction.

We don’t tend to think of the fragile and delicate as violent and dangerous. We admire the grace and beauty of the butterfly with no fear. We see the white swan, fluttering beautifully or the sweet gossamer-like beauty of Nina at her minimal breakfast, and we don’t fear them. We might even say that one egg and half a grapefruit is a normal and appropriate food for such a light and delicate being.
