Physicians literally murder (in the moral if not legal sense) patients because the state pays them to. The state doesn’t even force them to, it just offers them a bit of money to execute prisoners, and they do it willingly. The entire medical system in the USA is deeply, deeply corrupt. It does not exist to help people, it exists to serve its own capitalist needs. Yes, they still take an oath today; a meaningless one that permits all that and more.
