This was stupid and pure greed.Carlo thought he would live forever and if their was only 1 crime family he would be at the top.Can you imagine how much heat there would be on the boss if there was only 1 crime family in new york.And how was he going to expel members???He would of wanted to expel 100s of guys then these guys would of just formed their own crime family and they would of been bitter enemies with the Gambinos
