Recent work by Ingmar Persson and Jason Hanna has posed an interesting new challenge for deontologists: How can they account for so-called cases of letting oneself do harm? In this article, I argue that cases of letting oneself do harm are structurally similar to real-world cases such as climate change, and that deontologists need an account of the moral status of these cases to provide moral guidance in real-world cases. I then explore different ways in which deontologists can solve this challenge and argue that the most promising way to conceive of cases of letting oneself do harm is as nonstandard cases of allowing harm, supplemented with an additional argument for the moral relevance of one's own agency. The upshot is that cases of letting oneself do harm are both more theoretically challenging and practically important than has been acknowledged.
