This document discusses euthanasia and its classification. It defines euthanasia as voluntarily putting to death a patient suffering from an incurable, terminal, and extremely painful condition. Euthanasia is classified as either active or passive. Active euthanasia is an act of commission, such as a lethal injection, while passive euthanasia is an act of omission, such as removing a patient from life support. The document discusses how passive euthanasia was legalized in India in 2011 through the Aruna Shanbaug case, which allowed for the withdrawal of life support for patients in a vegetative state under certain guidelines.
