All depends the area your in.my vote for most violent would go to pagans or outlaws.go to martinsburg wva or winchester va and u have warlocks all over the place. The warbird warlocks not philly warlocks.there are also HA outlaws and pagans in and out the area.the warlocks will get together and roll out in a second wen pagans are spotted tho.i hve seen that but i didnt know they didnt get along till then
