For worst boss I'd say Joe Massino. Took over. family that was making money and doing fairly well, then surrounded himself with rats, including his brother in law, then ratted himself.
Actually for a while Massino was a pretty smart boss. He closed social clubs,got involved in wall street,and made his associates only refer to him by touching their ear. Then obviously the end of his reign was bad
I think the social clubs were no longer a way of life and closed on their own, but I may be wrong. I still believe that he had. short reign, and had some of his better men killed while surrounding himself with traitors. For one captain to rat on him would have been a big deal, to have 4 plus his underboss do it shows a lack of judgement. It also had to hurt the Bonanno's bad.
