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 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!
