The quote expresses the speaker's reluctance to harm anyone, specifically mentioning girls, even those who are vampires. This highlights a moral dilemma or internal conflict regarding violence and the value of life, suggesting that the speaker holds a certain degree of compassion, even towards supernatural beings. The mention of a "blonde" indicates a possible exception to this restraint, hinting at a deeper personal connection or specific animosity.

This complexity in the speaker’s feelings illustrates a broader theme present in the book "Breaking Dawn" by Stephenie Meyer, where characters often grapple with their instincts versus their ethical beliefs. The narrative explores the idea of love, loyalty, and the struggles that come with facing adversities, particularly when it involves those who are deeply connected to them, regardless of their nature.
