otherwise it would be anarchy
using this kind of punishment when you transgress are excellent
fines are also excellent for making it clear that the rules must be respected
They are good enough now and they are one of the big clubs in Serie A so it would be very unethical if they again destroyed their name with their stupid behavior just for the sake of short profits.
We have seen them recover better after that, I mean nearly what 10 cups in a row or something after they were relegated? That was a serious improvement for sure but they wouldn't want that again. It's better to stay here and get better, which they will, then go down and get batter later on. They lose so many players and time during that period, which could be used to dethrone Napoli and take back the title again in a few years at most. For that, they need to never do anything remotely shady again.
