New Zealand lawmakers pass euthanasia bill

Imagine there is a machine connected to someone and that if a button is pressed, the mahcine will kill the person it is connected to.

If the person who it is connected to presses the button, this is suicide. The assisted portion is that someone else has created and connected the machine, but it is still suicide because the machine cannot kill the person without the button being pressed.

If someone else presses the button, it is something other than suicide. In the case that the act of killing the person is classified as an "act of mercy", then it could be classified as euthanasia.

The article uses these two phrases as if they are interchangeable, but they are conceptually quite different.
