I chose those two doctors because I think that in the future the horrendous medical procedures that are being performed on young healthy bodies, the removal of healthy breasts, sterilisation by chemicals, destruction of bone density leading to crippling skeletal disease etc etc will eventually be viewed with as much horror as we now view Mengele and his experimental wickedness that was not motivated by a desire to do good. And incidentally I also include here the many doctors who performed hysterectomies and lobotomies to subdue anxious and distressed women who needed psychiatric not medical intervention. And Shipman was a doctor who knew exactly what he was doing, and chose to make decisions about his patients that suited his warped view of the world, not their well-being.
Any doctor or other medical professional who ignores the real needs of their patient, or invents needs that they then treat inappropriately, is in my opinion behaving in parallel with Mengele, Shipman and all those others who chose to damage not treat.
