Doesn’t have to be the monsters perspective (though that could work). It just has to empathize with it - show the horror of being made of constituent parts that neither fit nor really work together, the awareness of its own broken and blasphemous existence. The understanding of everything being horribly wrong without any wrongdoing on its part. The wish for a real attempt at life that can never be fulfilled, and the fear of death that its body remembers and longs for.

Could be a neat allegory for the unnatural lives of modern society!
