The gang that Walt has in employed Breaking Bad season 5 show a strange moral code -- leaving him 10 million dollars is extremely unusual behavior for criminals but might be consistent with actual white supremacists who respect Walt as a fellow white person. Do we have any indication that the gang really has any ideology or are they basically criminals with swastika tattoos?
