In "The Blind Assassin," Margaret Atwood explores the complexity of individual motivations and the lengths people go to justify their actions. The character's reasons for her choices are deeply personal and often starkly different from societal expectations, highlighting a sense of isolation in her rationale. This unique perspective gives her a certain ruthlessness, suggesting that she prioritizes her own logic over the conventional judgments of others.

This quote underscores the theme of personal agency in the narrative, reflecting how one's circumstances and experiences shape their decisions. The protagonist's willingness to act independently of common moral standards reveals her strength but also raises questions about the costs of such an approach. Atwood effectively illustrates the tension between personal necessity and societal norms through her characters' lives.
