It has been argued that, on Kantian grounds, pedophiles, rapists and murderers are morally obligated to take their own lives prior to committing a violent action that will end their moral agency. That is, to avoid destroying the agent's moral life by performing a morally suicidal action, the agent, while he still is a moral agent, should end his body's life. Although the cases of dementia and the morally reprehensible are vastly different, this Kantian interpretation might be useful in the (...) debate on the permissibility of suicide for those facing dementia's effects. If moral agents have a duty to act as moral agents, then those who will lose their moral identity as moral agents have an obligation to themselves to end their physical lives prior to losing their dignity as persons.

Thanks to recent scholarship, Kant is no longer seen as the dogmatic opponent of suicide he appears at first glance. However, some interpreters have recently argued for a Kantian view of the morality of suicide with surprising, even radical, implications. More specifically, they have argued that Kantianism requires that those with dementia or other rationality-eroding conditions end their lives before their condition results in their loss of identity as moral agents, and requires subjecting the fully demented or those confronting future (...) dementia to non-voluntary euthanasia. Properly understood, Kant’s ethics has neither of these implications. wrongly assumes that rational agents’ duty of self-preservation entails a duty of self-destruction when they become non-rational. further neglects Kant’s distinction between duties to self and duties to others and wrongly assumes that duties can be owed to rational agents only during the time of their existence.
