hi someone who saw the show lol
no gus and hector hated eachother in the show, possible spoiler alert
Gus fring had met a guy named Max and i believed helped him go through school for chemistry or something like that. Gus and him sold their product in cartel territory and tried to approach the cartel later to do business with them. the leader didn’t really like that they sold without permission and had audacity to ask after the fact and had hector kill his “business partner” right infront of him.
Hector is the one who was told to kill his partner max infront of him. Gus hated hector and i imagine didnt like the salamancas much in general but yeah
