协助自杀
Assisted suicide is contrasted to "Euthanasia", sometimes referred to as "mercy killing", where the person dying does not directly bring about their own death, but is killed in order to stop the person from experiencing further suffering. Euthanasia can occur with or without consent, and can be classified as voluntary, non-voluntary or involuntary. Killing a person who is suffering and who consents is called "voluntary euthanasia". This is currently legal in some regions. If the person is unable to provide consent it is referred to as "non-voluntary euthanasia". Killing a person who does not want to die, or who is capable of giving consent and whose consent has not been solicited, is the crime of "involuntary euthanasia", and is regarded as murder.
