Euthanasia and assisted suicide

13 min read

What is euthanasia?

Euthanasia is the act of deliberately ending a person's life to relieve suffering.

For example, a doctor who gives a patient who has terminal cancer an overdose of muscle relaxants to end their life would be considered to have carried out euthanasia.

Assisted suicide is the act of deliberately assisting or encouraging another person who commits, or attempts to commit, suicide.

If a relative of a person with a terminal illness were to obtain powerful sedatives, knowing that the person intended to take an overdose of sedatives to kill themselves, they would be assisting suicide.

Types of euthanasia

Euthanasia can be classified in different ways, including:

  • active euthanasia – where a person deliberately intervenes to end someone’s life, for example, by injecting them with sedatives
  • passive euthanasia – where a person causes death by withholding or withdrawing treatment that's necessary to maintain life, such as withholding
    in someone with

Euthanasia can also be classified as:

  • voluntary euthanasia – where a person makes a conscious decision to die and asks for help to do this
  • non-voluntary euthanasia – where a person is unable to give their
    (for example, because they're in a
    or are severely brain-damaged) and another person takes the decision on their behalf, often because the ill person previously expressed a wish for their life to be ended in such circumstances
  • involuntary euthanasia – where a person is killed against their expressed wishes

Depending on the circumstances, voluntary and non-voluntary euthanasia could be regarded as either voluntary manslaughter (where someone kills another person but circumstances can partly justify their actions) or murder.

Involuntary euthanasia is almost always regarded as murder.

There are alternative approaches and options for people with terminal conditions or those experiencing intolerable suffering.

An advance decision sets out the procedures and treatments that you consent to and those that you do not consent to. This means that the healthcare professionals treating you cannot perform certain procedures or treatments against your wishes.

What alternatives are there?

There are several alternative approaches and options for people with terminal conditions or those experiencing intolerable suffering.

Refusing treatment

If a person makes a decision about their treatment that most people would consider irrational, it doesn't constitute a lack of capacity if the person making the decision understands the reality of their situation.

For example, a person with life-threatening

may refuse a course of
because they would rather not tolerate the treatment's side effects for the sake of a slightly longer life. They understand the reality of their situation and the consequences of their actions and have made a perfectly rational decision.

However, a person with severe (psychotic) depression who refuses treatment because they wrongly believe that they have no hope of recovering and are so worthless they deserve to die would be considered incapable of making a rational decision. This is because they don't understand the reality of their situation.

Advance decisions

If you know that your capacity to consent may be affected in the future – for example, because you may become unconscious, you can arrange a legally binding advance decision (previously known as an advance directive).

An advance decision clearly sets out the treatments and procedures that you consent to and those that you do not consent to. This means that the healthcare professionals who treat you will be unable to carry out certain treatments and procedures that are against your wishes.

For an advance decision to be valid, you must be very specific about what treatments and procedures you don't want and under what circumstances. For example, if you want to refuse a certain treatment, even if it means your life is at risk, you must clearly state this.

As long as the advance decision is valid and applicable, the healthcare professionals treating you must follow it. In other words, it must cover exactly the condition you go on to develop and the treatment decision now at issue. There must also be no doubt about your capacity at the time of drawing up the advance decision.

CPR and 'do not attempt CPR’ orders

Cardiopulmonary resuscitation (CPR) is a treatment that attempts to restore breathing and blood flow in people who have experienced cardiac arrest (when the heart stops beating) or respiratory arrest (when they stop breathing).

CPR is an intensive treatment that can involve chest compressions (pressing down hard on the chest), electrical shocks to stimulate the heart, injections of medication and artificial ventilation of the lungs.

Despite the best efforts of medical staff, CPR does not have a good success rate, even in patients who are selected as appropriate for CPR.

In hospitals, only around 10-20% of people survive after having CPR, and survival rates are even lower in community settings.

Even when CPR is successful, a person can often develop serious and sometimes painful complications such as:

  • fractured ribs
  • damage to the liver and spleen
  • brain damage leading to disability

Also, many people who survive after having CPR need prolonged treatment in an

intensive care unit

Due to the low success rate of CPR and the corresponding high risk of complications, many people, particularly those with terminal illnesses, make it clear to their medical team that they don't want to have CPR in the event of cardiac or respiratory arrest.

This is known as a ‘do not attempt cardiopulmonary resuscitation’ or a DNACPR order. Once a DNACPR order is made, it's placed with your medical records.

If you have a serious illness or you are undergoing surgery that could cause respiratory or cardiac arrest, a member of your medical team should ask you about your wishes regarding CPR (if you have not previously made your wishes known).

A DNACPR choice is not permanent and you can change your DNACPR status at any time.

Some supporters of euthanasia have argued that DNACPR is essentially a form of

passive euthanasia
because it involves a person being denied treatment that could save their life.

The counter-argument to this is that the success rate of CPR is often so low and the risks of complications so high that it isn't the case that a person is being denied life-saving treatment.

Palliative sedation

Palliative sedation is where a person is given medication to make them unconscious and, therefore, unaware of pain. It's often used in cases where a person has a terminal illness.

Many terminal illnesses can cause distressing and painful symptoms when the person reaches the final stages. These can include:

  • muscle spasms
  • bone pain
  • unpleasant and sometimes frightening breathing difficulties
  • upsetting emotions and feelings, such as fear, apprehension and distress

Palliative sedation is a way of relieving needless suffering.

Although palliative sedation is not intended to end a person's life, the medication carries a risk of shortening their life. This has led some critics to argue that palliative sedation is a type of euthanasia.

A counter-argument is known as the ‘doctrine of double effect’. This states that a treatment that has harmful side effects is still ethical as long as it's in the best interests of the patient and the harmful side effects were not intended.

For example, very few people would argue that chemotherapy is unethical, even though it can cause a wide range of harmful side effects.

Withdrawing life-sustaining treatments

There are many different types of treatment that can be used to sustain life in people with serious or terminal illnesses. For example:

  • nutritional support through a feeding tube
  • dialysis
    – where a machine takes over the functions of your kidneys
  • ventilators – where a machine takes over your breathing

Eventually, there may come a time when it's clear that the prospects of a person recovering are nil and, in the case of terminal illness, the life-sustaining treatments are only prolonging the dying process.

In such circumstances, a doctor may recommend that the treatment is withdrawn so they can die peacefully. In some cases, palliative sedation (medication that relaxes a person and makes them drowsy) may be used while the treatment is withdrawn.

Arguments for and against euthanasia and assisted suicide

There are arguments both for and against euthanasia and assisted suicide.

Arguments for euthanasia and assisted suicide

There are 2 main types of argument used to support the practices of euthanasia and assisted suicide:

  • ethical argument – that people should have freedom of choice, including the right to control their own body and life (as long as they don't abuse any other person’s rights), and that the state should not create laws that prevent people being able to choose when and how they die
  • pragmatic argument – that euthanasia, particularly passive euthanasia, is already a widespread practice (allegedly), just not one that people are willing to admit to, so it's better to regulate euthanasia properly

Pragmatic argument

The pragmatic argument states that many of the practices used in end of life care are a type of euthanasia in all but name.

For example, there's the practice of making a ‘do not attempt cardiopulmonary resuscitation' (DNACPR) order, where a person requests not to receive treatment if their heart stops beating or they stop breathing.

Critics have argued that DNACPR is a type of passive euthanasia because a person is denied treatment that could potentially save their life.

Another controversial practise is known as palliative sedation. This is where a person who is experiencing extreme suffering, for which there is no effective treatment, is put to sleep using sedative medication. For example, palliative sedation is often used to treat burns victims who are expected to die.

While palliative sedation is not directly carried out for the purpose of ending lives, many of the sedatives used carry a risk of shortening a person’s lifespan. Therefore, it could be argued that palliative sedation is a type of active euthanasia.

The pragmatic argument is that if euthanasia in these forms is being carried out anyway, society might as well legalise it and ensure that it's properly regulated.

It should be stressed that the above interpretations of DNACPR and palliative sedation are very controversial and are not accepted by most doctors, nurses and palliative care specialists.

Arguments against euthanasia and assisted suicide

There are 4 main types of argument used by people who are against euthanasia and assisted suicide:

  • religious argument – that these practices can never be justified for religious reasons. For example, many people believe that only God has the right to end a human life
  • ‘slippery slope’ argument – this is based on the concern that legalising euthanasia could lead to significant unintended changes in our healthcare system and society at large that we would later come to regret
  • medical ethics argument – that asking doctors, nurses or any other healthcare professional to carry out euthanasia or assist in a suicide would be a violation of fundamental medical ethics
  • alternative argument – that there's no reason for a person to suffer either mentally or physically because effective end of life treatments are available; therefore, euthanasia is not a valid treatment option but represents a failure on the part of the doctor involved in a person’s care

Religious argument

The most common religious argument is that human beings are the sacred creation of God, so human life is by extension sacred.

Only God should choose when a human life ends, so committing an act of euthanasia or assisting in suicide is acting against the will of God and is sinful.

This belief, or variations on it, is shared by members of the Christian, Jewish and Islamic faiths.

The issue is more complex in Hinduism and Buddhism. Scholars from both faiths have argued that euthanasia and assisted suicides are ethically acceptable acts in some circumstances, but these views do not have universal support among Hindus and Buddhists.

‘Slippery slope’ argument

The slippery slope argument is based on the idea that once a healthcare service, and by extension the government, starts killing its own citizens, a line is crossed that should never have been crossed and a dangerous precedent has been set.

The concern is that a society that allows voluntary euthanasia will gradually change its attitudes to include non-voluntary and then involuntary euthanasia.

Also, legalised voluntary euthanasia could eventually lead to a wide range of unforeseen consequences, such as those described below.

  • very ill people who need constant care or people with severe disabilities may feel pressured to request euthanasia so that they're not a burden to their family
  • legalising euthanasia may discourage research into palliative treatments, and possibly prevent cures for people with terminal illnesses being found
  • occasionally, doctors may be mistaken about a person’s diagnosis and outlook, and the person may choose euthanasia due to being wrongly told that they have a terminal condition

Medical ethics argument

The medical ethics argument, which is similar to the ‘slippery slope’ argument, states that legalising euthanasia would violate one of the most important medical ethics, which, in the words of the International Code of Medical Ethics, is: ‘A doctor must always bear in mind the obligation of preserving human life from conception’.

Asking doctors to abandon their obligation to preserve human life could damage the doctor-patient relationship. Causing death on a regular basis could become a routine administrative task for doctors, leading to a lack of compassion when dealing with elderly, disabled or terminally ill people.

In turn, people with complex health needs or severe disabilities could become distrustful of their doctor’s efforts and intentions. They may think that their doctor would rather ‘kill them off’ than take responsibility for a complex and demanding case.

Alternative argument

The alternative argument is that advances in palliative care and mental health treatment mean there's no reason why any person should ever feel that they're suffering intolerably, whether it's physical or mental suffering or both.

According to this argument, if a person is given the right care, in the right environment, there should be no reason why they are unable to have a dignified and painless natural death.
