Medical diagnosis

Should medical misdiagnosis be a crime? Over the past 20 years, more and more criminal indictments have been taking place against doctors charged with negligence that resulted in the death of patients.  

Are doctors making mere mistakes or are they negligent or acting in a reckless manner resulting in criminal liability?  

Should criminal charges be brought without willful misconduct? Should a doctor lose their license?  Are there healthcare and/or business reasons that affect such decisions (whether positively or negatively)?

Should murder charges be brought against a doctor for the misdiagnosis a patient? 

Is there a difference between being overworked and lack of attention (negligence)?
