The character Yabu-san from James Clavell's "Shōgun" is portrayed as a violent man driven solely by self-interest. He disregards traditional values such as duty and loyalty, operating instead on a personal agenda. His cunning nature can sometimes reveal moments of brilliance, making him unpredictable in both alliances and rivalries. This duality renders him a significant threat to those around him.

While Yabu-san possesses certain dangerous qualities, it raises the question of whether there are any redeeming virtues to his character. The dialogue suggests a complexity in his personality, indicating that there might be attributes worth acknowledging despite his violent tendencies. The narrative invites readers to analyze the dynamics of morality within a character who embodies both commendable skills and troubling flaws.
