I think it’s not so nice from the doctor, to not warn you about what’s going to happen. Especially since you were the one carrying it out. I guess as a professional, they should know about the consequences of drugs they prescribe. Unless they’re somewhat incompetent, this may very well have been the intended/welcome/unavoidable outcome. And I think you’d have deserved a heads-up. Idk if that had helped you. But it’s probably hard. Some relatives will not let go. And you can’t refuse palliative care. So maybe the ethical way is to not talk too much after you got to a certain point.
