Abstract
Aquinas talks about a topic with which fans of Sons of Anarchy are all too familiar: homicide and murder. For Aquinas, murder is the private, intentional homicide of an innocent human being and always wrong. This is called the Murder Principle. Murder is the killing of an innocent. This seems to leave the Sons—a private organization rather than an arm of the state—without the legitimate authority to take a life. Watching Sons of Anarchy makes us increasingly suspicious of the moral authority of the state and its agents, who hardly seem like the competent “doctors” of Aquinas's amputation analogy. Contemporary philosophers have articulated the Doctrine of Double Effect (DDE), the gist of which states that it is sometimes morally permissible to bring about as a foreseen but unintended side‐effect what one would not be permitted to bring about intentionally. Aquinas's Murder Principle condemns much of what the Sons do.
