No you goddamned mongoloid
I know you only asked this to irritate me but fuck it, I'm mad

Raskolnikov is an embodiment of the sweeping nihilism in St. Petersburg during the mid 19th century, itself born out of a failed grasp at bourgeoise Socialism by the educated youths of the earlier 19th century. His descent into inhumanity and moral despondence is a criticism of the dangerous power of unbridled philosophical sophistry and twisted moralist manipulation which Dostoevsky saw as having been born out of that earlier era of Socialism. That he is ultimately saved by the trope 'absolved whore' and embraces Christianity has been alternatively interpreted as an earnest admittance of the need for religious absolution among the people of that era, or by some skeptics as a sarcastic satirization of many of the earlier Socialist's very ideals and a prediction of the bastardized return of that movement later under the Bolsheviks - both interpretations find validity in Dostoevsky's other works, notably Notes From Underground.

No he was Russian

How come he felt guilt for the crone, but not for Lizaveta?

Way to completely miss the point of the book.

No, but Dosto mentions that he's feverish and delirious (presumably from starvation). It suggests the author wanted to give him half an excuse, and lacked the conviction to make him truly cold-blooded.

Shh ... nobody cares about Lizaveta. Stop spoiling the book for everybody.

Nah more like some part of him thoroughly disagreed with the act and he felt tremendous guilt and shame and disgust for doing (or intending to do) it. Which presented itself as the symptoms you mentioned. I would disagree with that Dosto tried to use the illness as a way to absolve him of complete guilt for the deed and make him only partially guilty by making him sick. The feelings are the regular human reactions somebody would have to a deed like that. It's just that Raskol overrides them with his 'logic' and carries out the deed.

Looking back to your comment, I don't know if we actually completely disagree but I still like to put this out there.

I recall there being a passage in which the correlation between illness and crime is directly related, it would do well to read it again I think.
My interpretation that firstly, the feverish sickness is representative of the moral degeneracy and philosophical sophistry that the earlier user mentioned. It doesn't excuse Rodya for his crime, but serves as an explanation or at least a large factor. Secondly, I think that the sickness manifests because of the schismatic nature of Raskolnikov, who is torn between and confused by the new age sophistry and his inherent morality which may be Christian in origin. The sickness doesn't manifest in other mental criminals like Svidrigailov because he is purely representative of the "Napoleon" which Rodya is obsessed with.
