Motive vs. Psychology in Crime

Vance insists that motive is an irrelevant factor in solving crimes, as many people have similar motives; instead, he focuses on the unique psychological temperament of the murderer as the only reliable guide to guilt.

Vance contends that motive is irrelevant because everyone has motives; instead, individual psychology determines who acts on them.

The chapter explores Leacock's threat as a motive, but Vance's skepticism about Pfyfe's testimony suggests a deeper psychological complexity beyond surface motives.

Vance probes the psychological profiles of suspects like Leacock and Pfyfe, exploring their temperaments and potential motives, rather than relying solely on physical evidence.

Vance argues that despite the logical evidence against Leacock, the psychological profile does not fit, highlighting the tension between motive and character.
