These guys aren't scared of anybody.
I've met a couple of them (and no, I am not friends with anybody in that gang).
They have the same kind of mentality as suicide bombers, and no fear of consequences, regardless of if they even comprehend those consequences or not.
FWIW, the guys I met told me that in their countries, they kill judges and prosecutors who "stir up trouble" against them, they did not understand why this isn't normal practise here.
Like Pablo Escobar.
