Mood

"Cursed, cursed creator!  Why did I live?"  This is the line that the creature said after the Delacey family rejected him.  This was one of the main reasons that caused the creature to hate humans.  He finally decided that humans were awful when he saved the young girl, and then got shot.  All these instances affected the creature's mood.  Before all these experiences, the creature was actually pretty kind.  However, now that everyone treated him so terribly, he changed his mood completely and decided he was going to try to get back at Victor and kill his whole family.  Victor's mood was also affected many times.  Whenever Victor saw or thought of the creature, he became terrified and went through a depression.  It is a bit ironic because they both were the cause to their moods and feelings.
