This document discusses different types of euthanasia and physician-assisted suicide. It defines active euthanasia as intentionally ending a patient's life, while passive euthanasia involves withholding treatment to allow natural death. Voluntary euthanasia requires patient consent, while involuntary euthanasia does not. Arguments for allowing euthanasia center around patient autonomy and relieving suffering, though critics argue this could lead to a slippery slope and that killing is morally worse than letting die. The document examines philosophical debates on these issues but draws no firm conclusions.
