You are willfully ignorant.
Meds are titrated for symptom control.
Hospice nurses are NOT death angels.
It only takes one bad apple to carry out a murder spree. Often they were caught only if someone did a statistical analysis of caregivers and patients, which made it glaringly obvious that one particular doctor or nurse was systematically killing patients.
This was then.

Today, euthanasia has opened the floodgate. In the UK alone estimates are as high as 30,000 homicides a year, mostly by starvation, as it costs less. Often they are not voluntary, go against the written wishes of the patient, and the family are not notified ahead of time.
And the political left want that here, likely on a much grander scale.
I suppose it is ironic that in the UK, the infamous serial killing Dr. Harold Shipman (218 killed) was just ahead of his time. Were he to practice there today, he would be a lightweight compared to some of the murderous doctors and nurses still carrying out their deadly art.

He was only caught when he got greedy for the money of his victims.
