Raskolnikov sees Luzhin as small minded: Dunya, like himself, strives for ideals.

Does he keep the money?
"Well!" ejaculated the policeman, with a gesture of contempt, and he walked after the dandy and the girl, probably taking Raskolnikov for a madman or something even worse.
What does the little girl represent in the novel? I'm don't know. But the sexual molester, labelled as a Svidrigailov, represents the nastiest manifestation of the free thinking Napoleon, Raskolnikov's cherished ideal.
"Hey! You Svidrigaïlov! What do you want here?" he shouted, clenching his fists and laughing, spluttering with rage.
Although giving money to the policeman shows the generosity of Raskolnikov, I've long struggled to reconcile this generosity with his murder of the two women.
