I agree. Your friend died naturally.
[If all the woman wants is to turn off the breather, she is not committing suicide, she is living free of assistance for a few moments, and then dying naturally of her illness. I think people who want to die naturally are ok. But if you need to ask someone to give you a lethal injection or a pill or otherwise cause you to die, you are asking too much of them. They become your killer and it’s wrong to ask that of them. And it’s wrong to play God and do it to yourself. But if it’s time to “let go and let God”, ok.]
Exactly. Everyone born here has to die (aka “depart from the earthly tent) at some point. No one can stay in the perishable body forever, nor would any sane person want to.
But when we arrive and when we leave, is in God’s hands, and to try to wrest that power away from Him is pure destructive evil.
