Although insanity is definitely an emphasized theme in the novel, I would not use it as an excuse for Raskolnikov when he committed the murders. Initially, Raskolnikov did not portray characteristics of mental insanity. I think this became clear to us after the murders.
Raskolnikov’s motives for the murders were never defined. One could say that there was no motive and that is was due to his pride. Raskolnikov always felt this need to have control over people, perhaps this was his way of taking control.
Poverty could have very well been Raskolnikov’s motive for the murders, however this contradicts your original statement about it being his pride. The novel never mentions money involving Raskolnikov thereafter. I am leaning more towards the motive being his pride.
Alcoholism is definitely an issue in the novel. I like the point you made about Raskolnikov never being drunk in the novel despite his clearly delusional behavior.
(I think your themes are broad, therefore easy to expand upon. I also like that you posed very important controversial questions that can be researched and easily answered throughout your term paper.)
Keri:
I used guilt too as one of my themes. It is definitely very broad and apparent throughout the entire novel, so it would be easy to reference to. I like the reference you made to the mind and the body being directly connected.
Redemption is definitely seen at the end of the novel when Raskolnikov officially turns himself in and goes to Siberia. Although redemption is seen within his own mind, it was not enough, he demanded justice in society as well.
I do not feel like family is a strong theme in the novel. Although you are right, Raskolnikov’s family does not leave, he however, does. There is no stability within his family whatsoever, in fact it is almost as if he feels Sonia’s family is more a family to him that his own.
I think indifference might also be a weak theme because Raskolnikov does care about that others think of him. He might not care about physical appearance, however, he cares about what others say about him in regards to the murders. His paranoia definitely does not come as a result of indifference about what others think about him.
