Why did Raskolnikov make a confession and who persuaded him to do this?

There is no more fascinating detective story in the world than "Crime and Punishment". Raskolnikov - a criminal, his motives and arguments serving for self-justification, precede the murder scene, they are brilliantly described by Fyodor Mikhailovich Dostoyevsky, and there is no mystery in this matter.

The situation (at first glance) is simple: a young man, experiencing serious financial difficulties, wants to end poverty, killing an absolutely insignificant from his point of view creature. After this step, as Nikolay thinks, he will have opportunities for growth before him, and it is likely that he will be of great benefit to mankind.

The secret is not who killed, it is the question of why Raskolnikov made a confession. The whole novel is about this. The great writer does not give a direct and unambiguous answer, which allows the reader to reflect on this topic himself.

So, there was a murder and the investigation begins. The main character, like any living person, is connected with the people around him by various relationships. His friend Razumihin always aspires to help, the sister goes to St. Petersburg in the hope of a marriage that is successful in the material aspect, taking the mother with her. Luzhin, Dunin's bridegroom, is a kind of personification of Raskolnikov's idea of two grades of people, though completely cleared of conscience. He worships the only god-money. The aversion to this polished dandy brother of his bride seems not quite understandable, because they both consider themselves to be those who have the right to decide everything for others. However, it is this in part that gives an answer to the question of why Raskolnikov made a confession of guilt.

According to Dostoevsky, people really divide into two categories, but quite differently. There are those who are kind to others and seek to help them, and others who live only for themselves.

In Lebeziatnikov, the reader can see the prototype of a sort of "progressist", striving to "crush the foundations." In this sense, it intersects with the characters of another novel, The Possessed, in which F.M. Dostoevsky describes the emergence of social democracy in Russia. The communes, the abolition of the institution of marriage - this is how the future sees Lebezyatnikov.

And Sonya - the kindest and noblest creature, is forced to trade her body to support her father, a drunkard, whom she loves immensely, despite his vices. She is the complete opposite of Luzhin, and, it seems, the main character too.

Raskolnikov behaves strangely after the murder, which causes suspicions in the investigator, Porfiry Petrovich. That's where the subtle cunning, directed, however, to a good cause, the conviction of the criminal. The most important thing, and, of course, the nice quality of Porphyry is his peculiar frankness. It seems that he immediately realized who had killed the old woman, and, by ranting about the butterfly flying on the candle, the clever investigator does not hide who he means. The killer also understands this, but he can not do anything with himself, he just wants to get out, in these conversations he unconsciously seeks justification for his monstrous crime. Having destroyed or concealed all material evidence, he commits a series of suspicious acts and says many ill-considered words, confirming Porfiria's opinion that it is possible to lie inconceivably, but it is impossible to calculate the nature, nevertheless. The investigator exerts psychological pressure on the suspect , and it is logical to assume that this is why Raskolnikov made a confession.

But even here it's not so simple. Even knowing who the criminal was, the investigator could not even bring him to justice in those days, without a sufficient evidence base. To avoid punishment, at least, legal, Nicholas could just stop talking with Porphyry. And do not admit anything. Who persuaded him to surrender? Not an investigator, although he strongly advised to do so. Sonia Marmeladova convinced the murderer to bring himself!

Nicholas was so tormented by the impossibility of leading a normal life for him, and so tired of dodging all the time that his very existence was filled with unbearable agony. And it's not a question of repentance, he was not, just the murderer heeded the arguments of his beloved woman. That's why Raskolnikov made a confession.
