Frankfurt-style cases (FSCs) were introduced to undermine ‘the principle of alternative possibilities’ or PAP. They were designed to show that a person could be morally responsible even though the person had no alternative possibilities (APs) or could not have done otherwise. In this chapter, I assume a general knowledge of FSCs. They all involve a ‘counterfactual intervener’ who wants an agent to perform an action A and is prepared to intervene to prevent the agent from doing otherwise unless the agent is going to do A on his or her own. When the controller does not intervene and the agent acts on his or her own, it seems the agent could be responsible, though lacking APs because of the presence of the controller. PAP would thus be false.
