Raskolinkov's Redemption

In Crime and Punishment, Dotoevsky mentions in the last sentence that Raskolinkov is on the road to being redeemed, but never once does Raskolinkov repent. Even while in Siberia, after confessing his crime, Raskolinkov admits to pondering over his theory trying to find a fault yet not seeing where he was wrong. Then he has his illness where he dreams about an odd disease that sweeps over Europe. This disease infects men and causes them to believe that they, and only they, are in possession of the truth. The men in turn fight each other for power, killing those who get in their way as well as the comrades who are helping them. When Raskolinkov is relieved from his sickness he does not appear to draw any special meaning from his dream, but when his companion, Sonia, does not come to visit him in the following days, there is a marked change in his actions. Upon seeing Sonia again, he is overcome with emotion which he has not felt since the perpetration of his crime and he finally confesses his love for her. It is at this point where Dotoevsky asserts that in a following tale, perhaps, Raskolinkov will be redeemed.
Sonia, throughout the novel, acts as Raskolinkov's redemptive figure. In my opinion, Raskolinkov's change of heart towards Sonia signifies his inward state as an acceptence of his crime and the turning point of his repentence. The relationship between Raskolinkov and Sonia also expresses the need for love in partnership with regeneration.
In conclusion, although Dotoevsky does not bluntly state that Raskolinkov has repented, his changed affections toward Sonia and his sudden discovery of emotion show that he has, in fact repented of his crime.
