Do the doctors who sold Matthew Perry ketamine indicate something rotten in mainstream medicine?

The two doctors charged for their roles in the events leading up to actor Matthew Perry's death were both involved in a "side hustle": selling ketamine at a big mark-up to make extra money, above what they earned through legitimate practice. One was an internist-pediatrician and the other an emergency medicine physician.  Their cynicism was starkly evident in a text one sent the other about jacking up the price: "I wonder how much this moron will pay. Let's find out." It's easy to write off these doctors as just bad apples; regrettable examples of how difficult it is to prevent a small number of unethical people from making it through medical school and residency.  But what about the profit-making that occurs when thousands of physicians perform procedures, including surgeries, for which there is strong evidence of NO benefit from randomized controlled trials, but with all the risks of pain and complications during recovery and over the long term? From a patient's perspective is there really a difference between being subjected to predictable harm when you know your doctor is a drug dealer versus these practices within the mainstream of medicine where patients assume their physicians are acting in their best interests?   Which is the greater betrayal?
