I wasnt comparing the two, i was talking about there history dating back to the black hand gangs. The fact of the matter is that being in the mafia or being under its protection emboldens the criminals and thugs that are apart of it. There have been many cases where mob associates and even high ranking members have engaged in violent crimes or other criminal activity that has harmed civilians either intentionally or as a side consequence those criminals responsible did it in aid of the organisation even if it was on their own they are still a part of that group and under its protection. Heres some examples.
