Mercy killing, also known as euthanasia, is a controversial topic that has many different synonyms. Some of these alternatives include assisted suicide, peaceful death, end-of-life choice, and compassionate release. These terms describe the act of intentionally ending the life of an individual who is suffering from a terminal illness or condition that causes them unbearable pain and suffering. The term "mercy killing" has negative connotations and is often associated with unethical or illegal practices, which is why many individuals and organizations prefer to use alternative terms. Regardless of the terminology used, the debate over euthanasia remains a highly contentious issue, with supporters arguing that it provides a humane solution to end the suffering of the terminally ill, while opponents argue that it is morally wrong and against the sanctity of human life.
