Euthanasia, also known as mercy killing, is the deliberate ending of a person's life to relieve suffering from an incurable disease. It is a highly controversial topic debated around whether a human should have the right to physician-assisted suicide. While legal in three U.S. states, it remains debated due to concerns it could be abused or devalue human life, while proponents argue it allows patients to die with dignity on their own terms without unnecessary pain or suffering. The debate in the U.S. intensified after Dr. Jack Kevorkian carried out many assisted suicides, believing patients had a right to choose this option, though he was eventually charged with murder.
