In the opening chapter of 'Crime and Punishment', we are introduced to Rodion Raskolnikov, a former student who is living in dire poverty in St. Petersburg. As he walks through the bustling streets of the city, his thoughts are consumed by a dark and troubling contemplation of murder. Raskolnikov's mind is heavily burdened, reflecting his intense internal conflict and existential angst. He is not just wandering aimlessly; instead, his walk symbolizes a descent into the depths of his psyche, where he grapples with his own theories about morality and the nature of human existence.

Raskolnikov is depicted as a solitary figure, alienated from society and burdened by his financial struggles. His apartment is described as a cramped and squalid space, mirroring his mental state. As he interacts with the world around him, it becomes evident that he feels disconnected from those he encounters. The narrative portrays a stark contrast between Raskolnikov's inner turmoil and the vibrant life of the city, highlighting his isolation.

Throughout his walk, Raskolnikov contemplates a particular crime—the murder of a pawnbroker named Alyona Ivanovna. He is fixated on the idea that certain individuals possess the right to commit transgressions if it serves a higher purpose. This notion is rooted in his belief in the concept of 'extraordinary individuals,' who, in his view, are justified in breaking moral laws for the sake of humanity's greater good. The pawnbroker represents a figure of greed and exploitation, and Raskolnikov rationalizes that her death could potentially liberate him from his financial burdens and allow him to pursue his own ambitions.

As he walks, Raskolnikov's thoughts are tinged with paranoia and dread. He is acutely aware of the moral implications of his thoughts, yet he feels an overwhelming pull towards the act of murder. This conflict introduces the central theme of guilt that permeates the novel. Raskolnikov's struggle with his conscience foreshadows the psychological turmoil that will ensue after he commits the crime.

The chapter concludes with Raskolnikov returning to his dismal apartment, where he is further engulfed by his thoughts and the weight of his intentions. His internal conflict is palpable, setting the stage for the events to come. This opening chapter effectively establishes the tone of the novel, illustrating the profound psychological struggles of the protagonist and laying the groundwork for the exploration of moral philosophy that will unfold throughout the story.
