This article engages with the legal regulation of end-of-existence decisionmaking for novel beings, specifically assisted nonexistence for such entities. The author explains the concept of a legal model for assisted death by reference to the substantive features of legal regimes in three jurisdictions in which assisted suicide or euthanasia is lawful. He considers how these models might fit novel beings who may require or prefer assistance to end their own existence by reference to the constituent features—abstract legal ingredients—that models for assisted death share. The author argues that extant models may block some novel beings’ access to end-of-existence assistance or fail to track what matters to them. He then examines the merits of adopting a universal model for assisted nonexistence, that is, a legal framework whose substantive features capture the end-of-existence concerns of both human and novel beings. Consideration of a unified legal framework may illuminate the discussion of assisted nonexistence for humans and novel beings. However, the paper proposes that whereas novel beings may have similar interests to humans, they may be relevantly different also. The prima facie case for adopting a one regime to rule us all approach to assisted nonexistence may be defeated by reasons for divergent regulation.
