Euthanasia is the practice of intentionally ending a person's life to relieve them from suffering, often due to terminal illness or severe pain. It can be classified into two main types: voluntary, where a patient consents to the procedure, and involuntary, where it is done without the patient's consent. The legality and ethics of euthanasia vary widely around the world. In some countries, such as the Netherlands and Canada, it is permitted under strict regulations, while in others, it remains illegal. The debate surrounding euthanasia often involves discussions about patient rights, quality of life, and moral considerations.
