As far as the family with the most hits, I have to say that the Gambinos are probably the most brutal or violent family. This because Murder Inc was a subset of the Gambinos (The Mangano Family) and also because the Demeo crew was also a Gambino crew.
As far as the Family that is the most cruel in their killings....Chicago?
