So what would YOU do?

For Ken, there's no right decision. One's own decision is his right decision. Nobody is telling to go killing sick people. Ones who wanna live, let them if they have the money to sustain their body.

The judge of course made the right one. Denying him his right to die would mean condemn him to a prison of suffering.

Oh, I'd easily decide to die, and without fear (never been afraid of death: I don't even understand that; how can one be afraid of non-existence?! completely irrational).

A life is only worthwhile if it is meaningful. If one loses the capacity, in any way, of living what he/she determines to be a meaningful life, then it ceases to be worthwhile and is no longer a life worth enduring. (And let's not forget that mental anguish is among the worst torments of all).

And no matter how much we may disagree with someone about whether or not his/her life is meaningful and thus worthwhile, the individual has the absolute right to determine whether it is or not as well as to choose whether he/she will continue to live or not. Personal autonomy is a basic criteria for human dignity which endows all of our lives with even the possibility of being meaningful. As J.S. Mill so memorably put it: "Over himself, over his own body and mind, the individual is sovereign." (I would of added "over his own life").

So of course they both made the right decision in that Ken made the unassailable personal decision that his life was no longer meaningful and thus no longer worthwhile, and the Judge did by not impinging on Ken's absolutely uninfringible right to determine the course of his own life, including dying how and when he sees fit.

I'd go even further and hold that not only is suicide a rational, dignified choice (in fact it was judged to be so among many cultures and times, especially in classic Greece and Rome), but that normal healthy people who determine that their life is no longer worthwhile should be given access to painless methods and assistance for suicide (euthanasia). I would of course impose some judicious restrictions, such as a qualified professional evaluating that they are of sound mind to make such a decision, and no less than 1 year be given as a waiting period in which several sessions of therapy be conducted in order to perhaps salvage their lives and prevent any hastily made decisions as the result of personal tragedies or bad fortune, before the state could assist someone in their wish, and right, to die painlessly and with dignity.

No intellectually honest person can deny that many lives (most actually) are not worthwhile to those "living" them, that many just exist and never really live (or, at least, not anymore) and that these existences, if they were lost, would not harm the person, and, in fact, the person enduring them is actually suffering however modestly (the common unhappiness) or severely (those very depressed and in mental torment).

And that's the thing: nonexistence is not a harm, it can not be per its ontological status. But life, even in the best lives, always entails great and intractable harm (suffering). And, again, most people fall far short from truly flourishing (having, and maintaining, a worthwhile and meaningful existence all throughout their lives). So it is no great loss if and when people decide to end their existence; however, it is a great harm to suffer through a meaningless existence and to deny anyone their unassailable right to choose to end their existence whenever and however they wish.

Life qua life is simply of much less import than many take it to be, and should never be maintained at all costs, especially those that impose a life no longer deemed worthwhile to the one suffering under the burden of it. We all die, and it really matters not in the large view if that is tomorrow or decades from now, but what does matter is if we can maintain a life that we find personally meaningful, fulfilling, worthwhile. If we can not, then it would be irrational, even an unnecessary tragedy and harm, to continue existing.
