What would Tony have done if Carm followed the Jewish therapist's advice?
People always get on her case for not doing exactly what that guy told her to do, but I'm not sure that would be avisable considering who her husband is.
Also if she's taking the kids Tony is going to find out where she is. Meadow would call him to tell him what's going on and AJ would call him because he forgot he wasn't supposed to.
You can say that there's a mob code of honor against killing wives (especially one's own) but the whole thesis of the show is that these people don't actully follow any of those codes.
Not to mention that if she disappeared and went no contact the people back in Jersey could reasonably assume she was gonna talk to the feds (and maybe correctly). Which is clearly enough to kill a made guy's wife.
I don't know, am I being to generous to Carmella here? I just don't think taking the kids and leaving Tony forever would be a great strategy.
