I had a relevant experience with a day-care worker when my son was a toddler. I watched her haul a three year old boy roughly across the room by one arm and throw him in a corner while shouting at him. I stopped the room at that point, called her out, ended up in a three-month fight during which we had no daycare -- it ended with the woman being fired, and the director of this otherwise quite excellent daycare facility confiding to me that it was her experience that often good people with serious issues are drawn to professions that are anathema to their condition, but the destructive behavior was often hidden and hard to prove.

Clearly this woman is one of those cases. That kind of job takes a thick skin and a loving heart, and she appears to be lacking those.
