If he doesn't, he's devoid of a heart..

He hung around with Sonny for years, on a daily basis. Even slept lots of times on the couch in Sonny's apartment. Sonny liked him a lot and thought they were very close..

With what I've read about Sonny, he was one of the few wiseguys who actually was likable. I have respect for how he accepted his fate in the end and didn't take the easy way out.
A man's man in my book..
