There is also self-deception with respect to the cause of death. In Canada, when a patient dies by doctor-assisted death, the person completing the death certificate is required to record the cause of death as the reason that the patient requested euthanasia, not the act of euthanasia per se. This must lead to all sorts of moments of absurdity for physicians completing death certificates—do patients really die from advanced osteoarthritis? (one of the many reasons patients have sought and obtained euthanasia). I suspect that this practice is intended to shield those who perform euthanasia from any long-term legal liability should the law be reversed. But if medicine, medical progress, and medical safety are predicated on an honest acknowledgment about causes of death, then this form of self-deception should not be countenanced. We need to be honest with ourselves about why our patients die. 

There has also been self-deception about whether physician-assisted death is a form of suicide. Some proponents of assisted death contend that assisted death is not an act of deliberate self-killing, but rather merely a choice over the manner and timing of one's death. It's not clear why one would try to distort language this way and deny that “physician-assisted suicide” is suicide, except perhaps to assuage conscience and minimize stigma. Perhaps we all know that suicide is never really a form of self-respect. To sustain our moral and social affirmation of physician-assisted death, we have to deny what this practice actually represents. 

There has been self-deception about the possibility of putting limits around the practice of assisted death. Early on, advocates insisted that euthanasia would be available only to those for whom death was reasonably foreseeable (to use the Canadian legal parlance). But once death comes to be viewed as a therapeutic option, the therapeutic possibilities become nearly limitless. Death was soon viewed as a therapy for severe disability or for health-related consequences of poverty and loneliness (though often poverty and loneliness are the consequence of the health issues). Soon we were talking about death as a therapy for mental illness. If beauty is in the eye of the beholder, then so is grievous and irremediable suffering. Death inevitably becomes therapeutic option for any form of suffering. Efforts to limit the practice to certain populations (e.g. those with disabilities) are inevitably seen as paternalistic and discriminatory. 

There has been self-deception about the reasons justifying legalization of assisted death. Before legalization, advocates decry the uncontrolled physical suffering associated with the dying process and claim that prohibiting assisted death dehumanizes patients and leaves them in agony. Once legalized, it rapidly becomes clear that this therapy is not for physical suffering but rather for existential suffering: the loss of autonomy, the sense of being a burden, the despair of seeing any point in going on with life. The desire for death reflects a crisis of meaning. We deceived ourselves into thinking that assisted death is a medical therapy for a medical problem, when in fact it is an existential therapy for a spiritual problem. 

We have also deceived ourselves by claiming to know whether some patients are better off dead, when in fact we have no idea what it's like to be dead. The utilitarian calculus underpinning the logic of assisted death relies on the presumption that we know what it is like before we die in comparison to what it is like after we die. In general, the unstated assumption is that there is nothing after death. This is perhaps why the practice is generally promoted by atheists and opposed by theists. But in my experience, it is very rare for people to address this question explicitly. They prefer to let the question of existence beyond death lie dormant, untouched. To think that physicians qua physicians have any expertise on or authority on the question of what it’s like to be dead, or that such medicine can at all comport with a scientific evidence-based approach to medical decision-making, is a profound self-deception. 

Finally, we deceive ourselves when we pretend that ending people’s lives at their voluntary request is all about respecting personal autonomy. People seek death when they can see no other way forward with life—they are subject to the constraints of their circumstances, finances, support networks, and even internal spiritual resources. We are not nearly so autonomous as we wish to think. And in the end, the patient does not choose whether to die; the doctor chooses whether the patient should die. The patient requests, the doctor decides. Recent new stories have made clear the challenges for practitioners of euthanasia to pick and choose who should die among their patients. In Canada, you can have death, but only if your doctor agrees that your life is not worth living. However much these doctors might purport to act from compassion, one cannot help see a connection to Nazi physicians labelling the unwanted as “Lebensunwortes leben”—life unworthy of life. In adopting assisted death, we cannot avoid dehumanizing ourselves. Death with dignity is a deception. 

These many acts of self-deception in relation to physician-assisted death should not surprise us, for the practice is intrinsically self-deceptive. It claims to be motivated by the value of the patient; it claims to promote the dignity of the patient; it claims to respect the autonomy of the patient. In fact, it directly contravenes all three of those goods. 

It degrades the value of the patient by accepting that it doesn't matter whether or not the patient exists.  

It denies the dignity of the patient by treating the patient as a mere means to an end—the sufferer is ended in order to end the suffering. 

 It destroys the autonomy of the patient because it takes away autonomy. The patient might autonomously express a desire for death, but the act of rendering someone dead does not enhance their autonomy; it obliterates it. 

Yet the need for self-deception represents the fatal weakness of this practice. In time, truth will win over falsehood, light over darkness, wisdom over folly. So let us ever cling to the truth, and faithfully continue to speak the truth in love to the dying and the living. Truth overcomes pressure. The truth will set us free.
