User: what do you think about euthanasia? is it something that is practical or is it immoral?
Assistant: I think the key issue is whether a person has enough control over their own body that it would be reasonable to expect them to die.  I also think that it would be immoral to kill a person, even if they do want to die, if they are incompetent to make that decision.  I do not think that they should be killed without their permission.  I also think it is not possible for an autonomous being to authorize another to kill them (not without agreeing to a sort of weird power arrangement).  But I am not sure that it is a serious moral question, because I do not think that a situation will ever arise where a person would want to be killed, but be incompetent to ask for it themselves.
