We'll it really depends on the biker or mobsters but there there gets a point when criminals turn into scum. That's where I draw the line and those who cross it are monsters or cowards. I think bikers overall might go down for a fight but the alchohol and mob mentality helps in getting down with someone. I think street gangs are tougher than both since they live in the hood, where murders take place daily. They kinda become immune to it but I am not sure. Do I see street gangs having more hardcore members than both bikers and monsters. There are some crazy motherfuckers out there. Though prison gangs are the most dangerous in my opinion especially La Eme and AB. They are the elites of the criminal underworld and probably the most hardcore criminals on average around the world.
