Philosophers refer to people who have moral responsibility for an action as moral agents. Agents have the capability to reflect upon their situation, to form intentions about how they will act, and then to carry out that action. The notion of free will has become an important issue in the debate on whether individuals are ever morally responsible for their actions and, if so, in what sense. Incompatibilists regard determinism as at odds with free will, whereas compatibilists think the two can coexist.
