crea is a calabrian surname that's because i think he's calabrian
aniello is a southern name it's not used at all in north italy, so dellaroce is obviously southerner
i never claim there is a 'mafia-gene', the question is that the mafia is a south italy phenomen and you have to be born inside this mentality, completely different from north italian one
even tony senter was not made because north italian, imagine the others
