Right to die and the duty to live

Right to die and the duty to live names the intersection of two bodies of argument that developed separately and are beginning to collide: the law and ethics of assisted dying, built around people whose deaths are near and unwanted, and the prospect of interventions that make continued life a standing option rather than a fixed allotment. If aging becomes treatable, refusing treatment becomes a choice, and every question about whether death may be chosen acquires a mirror image about whether life may be declined.

§Two doctrines, separately built

Modern end-of-life law rests on a distinction that is stable in most jurisdictions and philosophically contested. A competent person may refuse any medical treatment, including life-sustaining treatment, and this right is close to absolute. Whether anyone may assist them to die actively is a separate question that most legal systems answer differently.

The US Supreme Court set out both halves in the 1990s: a 1990 case established a constitutionally protected liberty interest in refusing unwanted medical treatment, and two 1997 decisions held that there is no corresponding constitutional right to assistance in suicide, leaving the question to the states. Oregon's statute, in force from 1997, permits a physician to prescribe lethal medication to a terminally ill adult who self-administers it; roughly a dozen US jurisdictions now have comparable laws.

The Netherlands and Belgium legalised physician-administered euthanasia in 2002 under conditions of unbearable suffering without prospect of improvement, which need not be terminal. Switzerland has permitted assisted suicide since long before the modern debate, through a penal-code provision that criminalises assistance only when the motive is selfish — an arrangement that made it the destination for cross-border cases. Canada's regime began with a 2015 constitutional ruling, was legislated in 2016 for those whose death was reasonably foreseeable, and was extended in 2021 to people with grievous and irremediable conditions who are not dying; eligibility on the basis of mental illness alone has been postponed repeatedly. The United Kingdom's Terminally Ill Adults (End of Life) Bill passed the House of Commons in 2025 and was under consideration in the Lords; this is a fast-moving area and the position may have changed since.

What "right to die" usually means

In almost all existing law it means a right against interference — to refuse treatment, or to be assisted without the assistant being prosecuted. It is not a right to be provided with death on request, and no jurisdiction treats it as one.

§The suffering criterion and its instability

Every permissive regime rests on a criterion: terminal illness, unbearable suffering, or a grievous and irremediable condition. Each has proved harder to hold than expected.

Terminal illness requires a prognosis, and prognosis is unreliable at the margins. Unbearable suffering is subjective by construction, which is why the Dutch regime relies on physician assessment rather than an objective test. And any criterion defined by the absence of a remedy is unstable in a period of medical advance: a condition that is irremediable in 2026 may not be in 2036, which means the same person's eligibility changes without their condition changing.

This is the first point of contact with longevity research. If the frailty and multimorbidity that drive many requests are treatable — the claim behind the Geroscience hypothesis — then a person requesting assistance because their body is failing is requesting it for a remediable condition. Whether that should affect eligibility is a question no jurisdiction has faced. It becomes acute only if interventions extend Healthspan rather than lifespan alone; a therapy that adds years of dependency would strengthen the case for assisted dying rather than weaken it.

§The duty-to-die worry

Concerns that a permission would become an expectation predate the technology. A US state governor's 1984 remark that the terminally ill elderly have "a duty to die and get out of the way" prompted decades of argument, and the philosopher John Hardwig later defended a limited version — that a person may have obligations to family that bear on how long they seek to live.¹ Daniel Callahan had earlier argued for age-based limits on publicly funded life-extending care, on the ground that a health system cannot both pursue indefinite extension and meet other needs.²

The empirical worry is about pressure rather than duty. Disability-rights organisations and, in 2021, several UN human-rights experts raised concerns that Canada's extension to non-terminal conditions could make assisted death a response to inadequate housing, care, or disability support — that where the state funds death more reliably than it funds living, the choice is not free. Reported Canadian cases in which applicants cited unavailable services rather than intractable symptoms sharpened the objection. Disability rights and enhancement treats the broader argument about which lives medicine implicitly ranks.

§The duty-to-live worry

The symmetrical concern has had almost no attention, because the technology that would create it does not exist. It arises if life extension becomes routine.

Where continued life requires ongoing intervention — periodic Senolytics, repeated Epigenetic reprogramming, or whatever a working geroprotective regimen turns out to be — declining that intervention becomes an act rather than an omission. The distinction between letting die and killing, which carries enormous legal weight, becomes hard to locate. Someone who stops taking a rejuvenation therapy at 130 has not refused an extraordinary measure in the sense the doctrine contemplates; they have declined the ordinary maintenance that everyone around them undertakes.

Institutional pressures compound this. Pension systems, insurers, and employers all have financial interests in when people die, and those interests would run in the opposite direction from the ones that worry critics of assisted dying today. A society in which retirement is indefinitely deferred because working life is indefinitely extended, examined in The longevity dividend, is one in which stopping is a decision with economic consequences for others.

Is an indefinite life voluntary

Proponents argue that life extension adds an option and removes none: anyone may still decline. Critics reply that options with strong social defaults are not neutral, and that the pressure not to burden others, which currently pushes toward accepting death, would push toward accepting treatment with equal force and less scrutiny.

§Whether an unending life would be worth having

The philosophical literature on this question is older than the biology. Bernard Williams argued from the Makropulos case that an unending life would eventually exhaust the categorical desires that give a person reason to go on, leaving tedium rather than fulfilment.³ John Martin Fischer's reply is that repeatable pleasures do not exhaust, that a sufficiently long life allows new projects, and that Williams's argument assumes a fixed character which the immortal person need not have.⁴

Leon Kass makes a stronger claim: that mortality is not merely compatible with meaning but constitutive of it, because urgency, seriousness, and the structure of a life course depend on its finitude. It is the most substantive bioconservative argument and is treated in Leon Kass and Bioconservatism. Nick Bostrom's Fable of the Dragon-Tyrant is the standard reply, arguing that such reasoning is a rationalisation of an unavoidable evil that persists after the evil becomes avoidable.⁵ Neither position is empirically testable, and the oldest people who have ever lived, discussed in Maximum human lifespan, have not lived long enough to bear on it.

§Cryonics and the timing of death

Cryonics creates a live legal version of the problem. Preservation quality depends on beginning quickly after circulation stops, and legal death is required before any procedure can begin — so the process starts at the worst possible moment for the outcome its subscribers want. A California case in the early 1990s tested this directly: a man with a terminal brain tumour sought a court order permitting cryopreservation before his brain deteriorated, and was refused. Organisations such as Alcor Life Extension Foundation therefore operate standby procedures designed to compress the interval, without ever crossing the line the law draws.

Jurisdictions that permit assisted dying create a route that circumvents this, and a small number of cases have reportedly combined the two. It is the only context in which the right to die and the pursuit of indefinite life are not opposed but operationally connected, and neither the assisted-dying literature nor the Brain preservation literature has addressed what standards should apply.

§Open problems

No legal system has a category for a person who declines an available and effective life-extension therapy, and it is not obvious whether existing refusal-of-treatment doctrine would cover them or whether the case would be treated as suicide. Nor has any jurisdiction considered how eligibility criteria framed around irremediable conditions should be interpreted when the irremediability is a fact about current medicine rather than about the patient. Both questions are currently hypothetical. They stop being hypothetical the first time a geroprotective intervention works.
