 Pereboom’s argument presents Professor Plum in four different scenarios. In each scenario, Plum kills Ms. White while satisfying the conditions on desert-involving moral responsibility most often proposed by compatibilists (and described in earlier sections of this entry): Plum kills White because he wants to, and while this desire is in keeping with Plum’s character, it is not irresistible; Plum also endorses his desire to kill White from a higher-order volitional perspective; finally, Plum is generally morally competent, and the process of deliberation that leads to his decision to kill White is appropriately responsive to reasons.
