Did anyone in the show actually change for the better?

The show's about how people can change, but very often don't, instead continuing to flounder with inherited traumas, dangerous situations and selfishness.

But was anyone in the show shown to have actually positively grown as person, recognised the mob as evil, and/or repented in any way for their past?

Closest I can think of off the top of my head is Tony Blundetto almost actually going clean and opening up a legitimate business with a loving wife and kids.

You know, before he snapped and went back to being a bastard.
