I really don't see the difference, suicide or euthanasia is tragic, I've known people who have said about a person who has killed themselves "at least they are no longer suffering", just as you would if someone had been killed by euthanasia.And I don't disagree in the abstract, or even in the practical really.
All I've ever been saying is that it's kind of off that in order to be comfortable with assisted suicide/euthanasia and still treat traditional suicide as tragic we've just had to create two different "types" of suicide that don't really have any defining characteristic beyond how much of a warm and fuzzy we feel about it after the fact and that is something we should be able to talk about.
I'm not saying we should deal with suicide as a problem and I'm not saying people don't have the right to end their own life (but even those look at how weird that statement is one the surface) I'm just saying the idea the Person A is a hospital bed saying they want to die and Person B just sitting at home saying they want to die are that much of a different scenario is something I'm not 100% sure if I agree with.
