Any time Raskolnikov gives money to some poor person on the street. Even though he himself is poor and needs the money, and he criticizes himself for "throwing away" much-needed roubles, when he sees grief and suffering, his first instinct is to help.
Rodion finally confesses to Sonya that he murdered Alyona and Lizaveta, the latter of whom was her friend. Her reaction? To throw her arms around him and exclaim "No-one on earth is more miserable than you!" Doubles as a Tear Jerker.
