I think he is a serial killer who gets pleasure from the idea of killing. Being an abortionist is a means to this end.
Change some of the terms, and the doctor's name, and this could be a Nazi describing how he exterminated Jews. The abortionists hide behind "choice" and "constitutionality" and "privacy," and the Nazis hid behind their terms. So did slaveholders. But none of the arguments change the fact that the practice is murder and a total devaluation of innocent life.
BTW, I know other Jewish men of his generation, raised in NYC, atheists to the core, who have his exact politics. They are a dying breed. Their beliefs came from the rampant socialism and communism that infected NYC when they were teenagers in the 1930s and 1940s. Most are in the 70s and 80s now and soon they will all die off.
