But a __doctor__ enabling this kind of predatory behavior? Financial harm, rather than bodily harm, may not be against the text of the Hippocratic Oath and the various laws it has inspired, but I would argue it violates their spirit.
There are doctors who have done far worse things like assault young girls and prescribe chemo for patients who don’t need it, but they are in jail and (hopefully) will never practice Medicine again.
I guess the absence of laws against the behavior highlighted in OP means the doctor did nothing illegal, but the failure to prevent it is a systemic one. This doctor unambiguously betrayed the patient’s trust, and we need laws to prevent such things from happening. The Medical-Industrial Complex must be broken up.
