He wasn't involved at any real level. He was just the simpleton who ran the bar,and if he hadn't been any good at that then Sil would have gotten rid of him surely?
He was also a good target for Tony's frustrations.Maybe that is the main reason they kept him around
Tony didn't kill people — Ralph being a possible exception — because he was "annoyed" by them. There was always a "good" reason. He had never planned to beat the shit out of Georgie those times. It just happened.
Alpha Male with a short fuse. Tony was displaying his strength to Sil and Paulie when he flipped out over the ice comment. Thats why Sil said to Georgie to stop backtalking to Tony.
I just watched an episode where Gergie brings a singing fish to the Bing and Tony recalls Big Pussy as a fish with its mouth moving as he talked. He got ticked off and beat the hell out of Gergie with the fish.lol
In reply to Yogi,He is slightly involved with it all. As he did help Christopher dig up the body in the mud under the river.The fbi would have certainly seen him as an accessory.
