He's my favorite character, too, Proverbs. But he made his choice...
FYI, that garotting scene is based on a real-life incident that you might be interested in:

Around 1960, a war broke out between the Gallo brothers (on whom the Rosatos are based) and Joe Profaci, long-time boss of a Brooklyn Mafia family. The Gallos were a faction in the Profaci Family but they had a beef over territories promised to them. As the war dragged on, some Profaci higher-ups offered a "peace feeler" to eldest brother Larry Gallo. He met them in a bar, the Sahara Lounge, in Brooklyn, after hours. There they dragged him to the back and garotted him. A policeman happened by, came in, and broke up the garotting within seconds of Larry's demise. The NY Daily News had an unforgettable p.1 photo of the cops leading Larry away, a red mark across his throat. But Larry never squealed.
