Suicide and Homicide: Symmetries and Asymmetries in Kant's Ethics

When Suicide is not a Self-Killing: Advance Decisions and Psychological Discontinuity-Part I

Derek Parfit's view of 'personal identity' raises questions about whether advance decisions refusing life-saving treatment should be honored in cases where a patient loses psychological continuity; it implies that these advance decisions would not be self-determining at all. Part I of this paper argues that this assessment of personal identity undermines the distinction between suicide and homicide. However, rather than accept that an unknown metaphysical 'further fact' underpins agential unity, one can accept Parfit's view but offer a different account of what it implies morally: that the social and legal bases for ascribing a persisting 'personal identity' maintain the distinction between homicide and suicide.

How do roles impact suicidal agents' obligations?

In this paper, I assess the role responsibility argument that claims suicidal agents have obligations to specific people not to kill themselves due to their roles. Since the plausibility of the role responsibility argument is clearest in the parent-child relationship, I assess parental obligations. I defend a view that says that normative roles, such as those of a parent, are contractual and voluntary. I then suggest that the normative parameters for some roles preclude permissible suicide because the role-related contract includes a promise to provide continuing care and emotional support. I propose that as we have established criteria for morally acceptable reasons for cancelling, voiding, or amending a contract, we can apply these to the role responsibility argument to establish grounds for releasing a parent from his role-related and contractual obligations. Failure to fulfil one's contractual roles may not be blameworthy, depending upon the circumstances. I propose the factors determining culpability in failure to fulfil one's role-related obligations are: intention, voluntariness, diminished responsibility, mental capacity, and foreseeability.
