Tan Seow Hon, SJD LLM, LLB, Associate Professor of Law at Singapore Management University and Solicitor, in an Aug. 2017 Singapore Academy of Law Journal article, "The Case against Physician-Assisted Suicide and Voluntary Active Euthanasia," stated:

“[T]he empirical slippery slope cannot be ignored when one looks at the facts across the world… [T]here remains a real possibility of the extension of euthanasia to infants, those with mental incapacities or disabilities, and the elderly…

Indeed, this has materialised to some degree, whether by a formal extension of categories of persons to whom euthanasia is allowed, or by loose application of criteria by personnel involved in the administration of euthanasia. For example, Belgium removed the age restriction for euthanasia in 2014; assisted death has extended beyond the line originally drawn by the law in the Netherlands to patients regarded as legally and mentally incompetent and the possibility of extension to those who are not terminally ill but feel their lives are complete is being considered; severe psychic pain in and otherwise healthy person has been thought sufficient ground for requesting euthanasia; and researchers have found cases of non-voluntary euthanasia in the form of the termination of lives of disabled infants in the Netherlands.

Denying euthanasia honours the sanctity of life and the equal, underived, intrinsic moral worth of all persons, including the very weakest who can no longer contribute to society – principles of which so many other laws pivot.”
