Self-Analysis is a recurring idea in the book. The fact that the writer of the book calls himself an "antihero" indicates that he's conducted extensive self-analysis. The "Notes" are filled with those sections of analysis. For example, when Liza is in his arms in his apartment, he is suddenly filled with an emotion that he correctly identifies as passion but with revenge as the ultimate motive. He says that she is afraid only for a moment. Afterward, he says that he's done her an incredible wrong. When she leaves, he almost follows her but says that he knows he couldn't make her happy because he isn't the sort of person who could make anyone happy in the long term.
