Cuthanasia appears to be a typographical error or a misunderstanding of the term "euthanasia." Euthanasia refers to the practice of intentionally ending a person's life to relieve suffering, often in the context of terminal illness. It can be voluntary, where a patient consents, or involuntary, where the patient cannot provide consent. The ethical, legal, and moral implications of euthanasia vary widely across different cultures and jurisdictions.
