If Castelllano didn't get his own crew to whack him Roy would have been running that family eventually
If Roy hadnt been whacked when he was then the cops would have busted him. Dom Montigilio ratted later that year and Walter Mack was building his case stronger each day. 1983 would have been Roys last year as a free man!
I think Walter Mack was quoted as saying something about it after they found Roy dead . Something along the lines of Roy getting whacked being easier than trying to build a successful case against him .
I've just finished murder machine and that is infact what Walter said, by killing Roy they made the case easier to make.
