All those years risking life and limb and prison time, the notoriety, the lifestyle, in the end it was merely a trifle to Junior.
I wonder if that was a big wake up call to Tony.
I think Tony was waaaaay too far past redemption by that point...Throughout the entire series we see Tony getting darker and darker. Example: Would Tony have killed Chris in Season 1 or 2 or 3, even under the same circumstances? I seriously doubt it. Would he have considered killing Paulie just for talking too much in general? I don't think so. But by Season 6B I think Tony would have killed anyone, save maybe Meadow and A.J (but not Carmela), if he thought it might save,or even benefit, himself in the long run.
