So the pt commits suicide and dies .. or the pt does not commit suicide and dies anyway. Same end - one is just quicker than the other.
That's how I see it.
Frankly, if I'm going to die anyway, why not go now, before suffering and putting my family though sufferng?
I know a nurse who fought and survived breast cancer - she said that if the cancer ever came back, she'd steal a vial of insulin from the hospital and give herself the entire vial and go out on her own terms...
