Emotions play a critical role in both moral deliberation and moral action. Understanding the emotions and how they ought to interact with theoretical principles is an important part of fulfilling our duty of due care in moral deliberation. By examining the Nazi police squads and the Nazi virtue of “hardness,” we can come to see how ordinary people can suppress their emotions in order to carry out morally odious tasks. We can then see that the methods we use to live with our treatment of nonhuman animals bear striking similarities to the methods used by those in the police squads. Ted Bundy, a psychopath, suggests that a lack of emotions can hinder our ability to grasp moral concepts, thus showing that even while emotions must be regulated by theory, they also play an important role in any full understanding of the significance of moral demands.
