Crime and Punishment
How we cite our quotes:
[Luzhin:] "[…] immediately after your visit I found that a hundred-rouble note was missing from my table, in the room of my friend Mr. Lebeziatnikov." (5.3.5)
If Luzhin had his way, Sonia was about to start really suffering. Fortunately, there are some decent people in this novel, not the least of which is Andrey Semyonovitch Lebeziatnikov. Luzhin's plan backfires and the suffering boomerangs back on him.
[Raskolnikov] had to tell her [Sonia] who had killed Lizaveta. He knew the terrible suffering it would be to him and, as it were, brushed away the thought of it. (5.4.1)
Raskolnikov knows that confessing, the act of speaking his crimes, causes him to suffer – yet, he can't stop doing it. He needs to tell. The suffering of telling is less than the suffering of not telling.
[Porfiry:] "So I suspect now that Nikolay wants to take his suffering or something of the sort." (6.2.24)
Porfiry thinks that Nikolay is taking the rap for the murders to achieve the kind of suffering only available to the actual murderer. He blames this on Nikolay's religion, which celebrates suffering as a means to access divine love.
