Dynamic Character

"What does it avail that now I ask thee to pardon me?"

I believe that the creature is a dynamic character in this novel. Earlier in the novel, he was set on making Victor's life miserable. He killed his brother and his wife! But now, in this excerpt, he is extremely remorseful because he realizes that he is the reason for Victor's poor health that led to his death. He went from jeering at Victor when he was mourning over his murdered wife to crying over Victor's dead body. Creature says he will go and burn himself alive. He wants to do this in order to rid himself of his miseries. For the first time, he is experiencing overwhelming grief, and he cannot deal with it.
