That’s a good reason to have a process for euthanization that is as thorough as the one for letting people die slowly by cutting off feeding tubes or machines that assist with bodily functions. Or even like the Do Not Resuscitate (DNR) choice that people can make when they are of sound mind.

It is not a good reason to ban it and make everyone else suffer by dragging out death when it is an inevitability and the person is ready to go.
