Why does Raskolnikov confess?
Porfiry's certainty, Sonia's demand, Svidrigailov's death, love for his family, and the exhaustion of isolation converge. He still lacks full repentance when he enters the police station.
What is his sentence?
He receives eight years of penal servitude in Siberia, a comparatively merciful sentence shaped by mitigating evidence and his voluntary confession.
What changes in Siberia?
At first almost nothing inwardly: he resents failure more than murder. Sonia's illness and return awaken fear, love, and a new relation to life that his theory could not provide.
What does the final dream mean?
A plague of absolute individual certainty destroys social reality because everyone believes himself uniquely right. It enlarges Raskolnikov's theory into a vision of universal isolation.
Is redemption complete?
No. The narrator explicitly presents it as the subject of another possible story. The novel ends at the first conscious beginning of transformation.
Themes and What the Ending Means
Ideas and responsibility: Abstract permission collapses when applied to actual bodies, relationships, fear, and guilt.
Isolation: Raskolnikov's intellectual pride depends on separation; recovery begins through relation and confession.
Poverty and humiliation: Economic desperation shapes choices without making every poor character morally identical.
Suffering: The novel questions whether suffering punishes, purifies, degrades, or merely exposes what a person loves.
Doubling: Sonia, Svidrigailov, Luzhin, Porfiry, and Razumikhin each illuminate a possible path or distorted reflection of Raskolnikov.
