assisted suicide vs suicide prevention

[Godscreated]

I believe it should be carried on only when illness is too severe that the patient is considered already ruined and doomed.

Have an ischemic stroke as an example that comes with partial or full paralysis. The person is already dead if the stroke happens in a crucial spot in the brain.
I would say it should be a choice the person does when they're alive before they lose ability to speak or something far more terrible occurs.

That would be no extreme measure to be taken to keep the person alive, this I  agree with, they want to go naturally, my parents both told me they did not want extreme measures taken to keep them alive.
