I can't talk about the specific case mentioned here, but... Morphines are indeed used in palliative medicine to unofficially end the suffering. This is a fact that is not talked about much, because it is highly illegal. I had a chat with a palliative doctor just 2 years ago, and she confirmed this to me. At some point, they decide it is finally enough, and overdose. IMO, a very humane approach. I hereby thank everyone involved in such things for taking the risk to shorten the final days of a dying person, to avoid unnecessary pain. I can only hope, when my time comes, that some angel around me will do the same for me.
