The truth is, if a werewolf behaved like this psychopath it wouldn't be because he was part animal, but because he was still too human. Only humans kill for sport.
The quote from Kelley Armstrong's "Bitten" suggests a deep reflection on human nature and morality. It contrasts the behavior of a werewolf with that of a psychopath, emphasizing that the latter's cruelty stems from a distinctly human trait. Unlike animals, humans are capable of engaging in violence for pleasure, revealing a darker side of human psychology.
This perspective invites readers to consider the complexities of identity and the fine line between man and beast. The notion that a werewolf would exhibit less brutality if truly animalistic introduces a commentary on humanity's capacity for inhumanity, suggesting that it's our conscious choices, rather than our primal instincts, that can lead to such malevolent actions.
