Yeah I feel like the whole point of Tony is that, despite his villainy, he’s not a sociopath and actually has a strong sense of right and wrong. It’s just that what’s right and wrong to Tony is a lot different than what’s right and wrong to someone who’s not a waste management consultant in North Jersey. >!At least that’s how he is at the beginning of the show. I think of Tony’s overall arc on the series as him gradually coming to terms with his own evil, especially given how his relationships with Chris and Dr. Melfi end!<

Neither of them are just ‘sociopaths’ in the medical sense. It’s just a label and often used as a blanket term for people lacking empathy. While yeah they both -do- lack empathy in general guilt about things eats at both of them. They are not -without- empathy, they make themselves believe they’re in the right of things and whatever violence they do “has to happen” b/c of their whole mafia mentality. The only one on the show i’d really label a ‘sociopath’ is the guy who clubbed vito’s brother and got smoked by bacala sr

Edit - and melfis rapist if you want to consider him a character
