This is such an oversimplified view of how medicine works. I'm not even sure how to begin a counterargument. In medicine, bad outcomes can occur without being sure of the cause. For example, let's say a patient who currently smokes gets lung cancer. Did the patient get lung cancer from smoking, or is this a sporadic non-smoking related cancer? There's no way to definitively find the answer to that question. But for the sake of discussion, let's say it is due to smoking. Do you fault the patient for smoking and not quitting? Or do you fault the doctor for being unable to convince the patient to quit smoking?
