It is tough to compare one mafia member against another, or even to compare one killer from one OC category to one from another. The first problem is how many they killed, the stats are ridiculous, and come from gossip. Franzese never killed anywhere near as many as claimed, unless he was killing inmates in the prisons where he did spent so much of his life. I think the highest counts may have been in Chicago during the times leading up to The Saint Valentines Day Massacre.
