Frankenstein Essay Help: ...tragic vision of the work as a whole?

Its saying that you have to pinpoint a tragic character like Frankenstein or his monster who seems to bring 'tragedy' wherever they go. The teacher wants you to tell them in what ways did they effect the other characters in the book and the common theme of the consequences of knowledge among others. Id stick with Frankenstein and how his experiment caused the murder of everyone he loved including himself as a start. Good luck!
