This paper examines the rationality of other regarding preferences on end-of-life decisions such as euthanasia and suicide, by extending the discounted future utility model. The discussion shows that individuals with other regarding preferences may act upon choices contrary to their ex-ante preferences, such that they are choosing to remain alive rather than opting for euthanasia or suicide. The policy extension is that individuals with close friends and/or family are less likely to take their own life, but can also prolong their own suffering because of the same attachments.
