[Marmeladov:] "I ought to be crucified, crucified on a cross, not pitied! Crucify me, oh judge, crucify me but pity me!" (1.2.36)
Like many of the characters in this novel, Marmeladov thinks that if he can suffer like Christ, he might be purified. At first, he says he doesn't want pity, just crucifixion. Then, he says he wants both. This strikes us as a very human emotion. If we have to suffer, we want others to feel a little bad for us while we are doing it.
[Sonia, reading:] "And when He thus had spoken, He cried with a loud voice, Lazarus, come forth.
"And he that was dead came forth." (4.4.183-184)
Lazarus is almost as important to Raskolnikov as Napoleon is. It gets pretty bizarre. If he can be a Lazarus, he can be reanimated, awakened from the death of his life.
