He even has reason for murder.
As the reader has effectively entered the mind of this strange man, we learn of his beliefs. In delineating his explanation of how spitefulness and insanity lead him towards murder, he interjects three parenthetical phrases to stabilize and support his wobbly new hypothesis.
While the superiority complex sets him apart from the society in the beginning, his piercing conscience distances him from people later on in the novel Looking at his theory and applying it as a tool for analysis of Raskolnikov himself leads not only to a deeper understanding of this idea but also of Raskolnikov Avoiding suffering only causes it to intensify.
The nihilistic view that Raskolnikov shares with Pisarev is that freedom must be attained in order to improve society. Raskolnikov is still a fascinating character to dive into, and he is so much more complex than just an author stand-in.
This is blamed on the years that he spent in prison. He vaguely starts to sense that his prided mental abilities are pitifully limited and that man, being a fundamentally irrational creature, is incapable of purely logical and consistent thought. He reasons that, since she would not understand it anyway, he does not have to offer an explanation.
Therefore, his conscious is telling him that committing murder is a bad decision by reliving a similar memory that terrified him in his childhood Then his cold and unfeeling side comes through and he is repulsed by the wickedness of our society. When Raskolnikov does so, he stops suffering from guilt, shame, and madness.
Raskolnikov and Pisarev also differ in that Pisarev believes in a man-society relationship in which one will help others for the sake of self-satisfaction.
