Possible Thesis

1. Since Raskolnikov constantly kept pushing people away, I was thinking that alienation could be a possible theme to talk about. As Raskolnikov becomes more obsessed with the murder, he hides away in his apartment. Even before the murder Raskolnikov alienated himself from others especially when it involved his old classmates. 
2. It seems like almost every character in the book tends to suffer from something. Raskolnikov, Dunya, Sonya, and Svidrigailov suffer from various hardships in their lives that cause them to act a certain way. 
3. While I was reading, I noticed that every character had at least one foil in the story. Raskolnikov can be compared to many of the other characters in the story. From what I've noticed, when one person in the book does something, someone else reacts to it in an way that seems to contradict the action. 
4. Raskolnikov tends to have a unique reaction to committing the murder. His guilt is the drive to all of his random actions and abnormal behavior when the murder is brought up. Because of this, I would like to talk about the psychological effects of the crime. Raskolnikov's punishment is not a physical one but a mental one which actually serves the crime better than be locked up in a cell where he receives food and shelter for free. At the same time that Raskolnikov's guilt destroys him, he praises himself for not getting caught and tries to use his theory of crime to justify his actions.
