Walton's letters at the beginning of Frankenstein help provide context and structure to the story and introduce themes that become important later. Shelley uses multiple settings to add exoticism and interest readers in different places. The Monster's monologue aims to gain sympathy from readers by explaining what it has done since being abandoned by Victor. Victor does not finish the second creature because he does not believe the Monster's promise to avoid humans and worries about future humans cursing him for creating a race of devils.
