It's quite a long article; here is the part where Dr. Alice Miller talks about a mad scientist.
“Sadism is not an infectious disease that strikes a person all of a sudden. It has long prehistory in childhood and always originates in the desperate fantasies of a child who is searching for a way out of a hopeless situation.
An American professor, for example, has been conducting experiments for years with brain transplants. In an interview with the magazine Tele, he reports that he has already succeeded in replacing the brain of one monkey with that of another. He does not doubt that in the foreseeable future it will be possible to do the same thing with human beings. Readers have a choice here: they can be thrilled at so much scientific progress, or they can wonder how such absurdity can be possible and what purpose such pursuits can serve. But a piece of seemingly unimportant information may produce an "aha" reaction in them, for Professor White speaks of "religious feelings" connected with his endeavor. Questioned by the interviewer, he explains that he had a very strict Catholic upbringing and in the opinion of his ten children had been raised like a dinosaur. I don't know what is meant by this, but I can imagine that this image refers to antediluvian methods of child-rearing. What does that have to do with his scientific work? Perhaps this is the unconscious background for Professor White's experiments: by devoting all his energy and vitality to the goal one day being able to transplant brains in human beings, he is fulfilling his long-harbored infantile wish to be able to replace his parents' brains. Sadism is not an infectious disease that strikes a person all of a sudden. It has long prehistory in childhood and always originates in the desperate fantasies of a child who is searching for a way out of a hopeless situation."
