morally responsible for the result
What does that mean though? Responsible for all they do? They are property? What, are parents morally responsible for?
"Your children are not your children They are the sons and daughters
of life's longing for itself They come through you but not from you
And though they are with you yet they belong not to you You may give
them your love but not your thoughts For they have their own thoughts
You may house their bodies but not their souls For their souls dwell
in the house of tomorrow Which you cannot visit, not even in your
dreams. You may strive to be like them But seek not to make them like
you For life goes not backward, nor tarries with yesterday"
-from 'On Children', by Kahlil Gibran
It is certainly a philosophical and a moral question, whether to continue.
"Should I kill myself, or have a cup of coffee? But in the end one
needs more courage to live than to kill himself." - Camus
Camus gets at how it is a deeply personal, an existential question.
But then again, there is something very selfish, even solipsistic, about not considering the effects your passing would have on others. In 'The Outsider' I think Camus is discussing that, it is easy to act in the moment like an Absurdist, but to actually be one means being reconciled with whatever the consequences turn out to be, not ignoring them or wishing them away or wishing to have been different or acted differently.
Assisted dying in the face of serious illness & suffering has to be allowed by almost anyone, unless they have a religious objection. There was a fairly recent case in Canada, about allowing euthenasia for mental illness, for someone in enduring severe mental anguish. One issue was that funding hadn't been available to explore all treatment options, so there is a risk of this being financially motivated, as there can be around encouraging the elderly to die whether or not they truly wish it. But based on the idea euthanasia can be ok, those arguments require admitting death can be an acceptable choice, in the face of suffering.
One of the biggest issues with choosing early death, is that it closes off possibilities. Deathbed revelations, or insights, or generally how we die, have lasting repercussions. It's very intetesting what is being discovered about psychaedelics and end-of-life care, eg The Potential of Psychedelics for End of Life and Palliative Care. A shift in perspective for the dying person doesn't just affect them, but the whole circle of people around them. As long as we are alive, we can change perspective, end feuds, undo harms, redeem unfinished projects or broken promises. It is widely reported that dying people find new significance and importance to such an area.
