Dr. Healy is a good person, he just allowed himself to get involved with the wrong person (Alma). If she did all the ordering of drugs... why didn't she question the quantities? She was trouble the moment she stepped into that office & took over. I'm sure that's why Jessie left!
That was Healy's office. He knew what was going on. He got greedy. Plain and simple. Don't make him out to be the victim.
