"A ghastly grin wrinkled his lips..." (121). I feel like the creature brought this upon himself. The way that the tone and descriptive words make it seem as though the creature was being evil. He may have, in fact, just really been smiling because he was happy again. However, I think that he was glad that he was able to threaten someone into doing something. I don't really blame Victor for reacting this way. I would have probably done the same thing. However, I can also understand why the creature is so mad now and plans revenge.
