You don't get it - it is basically euthanasia ... they start the drip, and keep upping it until the patient gets into a coma. Rather than manage the pain by increasing/decreasing as needed, so that the patient can continue living, they keep upping the dose until they die ...
If you KNOW a person was murdered by morphine, go tell the police. Otherwise you are just sermonizing.
I have a sister who takes morphine every day and has since age 45. She has fibromyalgia and could not function at all without it. Maybe one day she will commit suicide, as so many patients with fibromyalgia do, just to escape the utter misery of constant unbearable pain.
She would tell you to take your sermon and shove it where the sun doesn’t shine.
