Ok, so we all know that the most dangerous people are people in the mafia, but lets list the 3 most dangerous mafias:
- Japanese mafia (Yakuza) moderate
- Italian mafia (Cosa Nostria) dangerous
- Russian mafia (Bratva) most dangerous

You have seen "The Sopranos", right? Well, it tells you what mafias mean! Yakuza, will beat you, Cosa Nostria, will "take care of you", and Bratva, will plain out kill you! You don't need to worry about Yakuza, they mostly operate in Japan, or the Cosa Nostria, the operate in New York and California, but keep your eyes on Bratva, the operate almost everywhere, Alaska, Pennsylvania, NY, California, you name it, just learn how to keep out of sight, so the Russian mafia don't get you!
