I believe so. As someone currently diagnosed with an incurable, untreatable illness which will kill me over the course of the next decade or two, I imagine suicide will be my only recourse come the end. The idea of employing a handgun doesn't scare me particularly, but it does make me wonder: Since suicide is a felony, there's really no punishment involved if I were to commit a number of other felonies prior to painting a Cobain rainbow across whatever wall my corpse slid down with my trusty .45 calber paintbrush.
I'm not trying to sound morbid here, or to encourage any lawlessness, but when a person is set on a particular act, he's going to do it whether or not it's illegal. And if that act happens to be illegal, well, what's one more crime along the way? A person who's going to do that has no punishment save his own conscience, so it's not so much a question of how a person dies that springs to mind as how many people the soon-to-be deceased intends to take with him.
As such, I think legalizing doctor-assisted suicide is probably a safe choice for the public at large. It deters the mind from going down that road and coming up with lists.
