In Frankenstein, what is Victor Frankenstein feeling when he runs away in horror at this creature he has just made?
In Mary Shelley's Frankenstein, Victor Frankenstein is very specific about the feelings he has when he first comes face-to-face with his creature.
In chapter five, Victor expresses exactly how he feels when first peering into the "dull yellow eye of the creature" as it writhed and convulsed on the table (assumed as the exact placement of the creature is never given). Victor, as told through Walton's narrative (do not forget that the tale is told by Walton as detailed by Victor--which makes the story a multiple narrative), is horrified at the sight of the creature. Victor details that he had chosen the different parts of the creature's "to-be" body because of their beauty. It is not until the creature is whole, and staring at Victor, that he recognizes the atrocity before him.
Victor, still in chapter five, describes that his dream of a beautiful creature has died. The creature is not beautiful to Victor; instead, Victor is filled with "breathless horror and disgust." He is so unable to "endure the aspect of the being" he has created that he leaves his laboratory and begins to pace his bedroom. Exhausted, Victor collapses and falls into a restless sleep where he dreams of Elizabeth turning into his dead mother, Caroline, as he kisses her.
Awakening, Victor finds that the creature is standing over him, "eyes fixed on" him, "jaws opened" and muttering inarticulate sounds. So horrified by the creature, Victor flees his flat (apartment).
Therefore, Victor's feelings are very openly stated and alluded to (at the same time). Not only is he horrified and disgusted by the creature, he is so frightened that he runs away.
