Santino was a good #2 or even #3 man but he could not think strategically and when his temper was up his rationality went out the window.
A good historical comparison would be Patton. Brilliant, dogged commander with his division just as mean as he was.
Except he was also (let's admit it) a psychopath, too impulsive, cause too many (pointless) diplomatic rows with his fellow Allied commanders, and if he had run D-Day he would have launched it against Calais. Exactly where the Nazis were expecting it.
Or to use a pro wrestling metaphor: Sonny is Arn Anderson, not Ric Flair.
