Exactly these guys on here acting like Walt hasn't bodied people who came after him. Gus thinking he could use Walt and kill him was the beginning of everyone's downfall . He told the cartel when the twins wanted to kill Walt he was going to kill him when he was done . Walts not dumb he saw the writing on the wall with gale and he started watching his back . Then once Walt Managed to get to gale was proof he's on the ball Gus should've been on alert . He should've paid Walt off after killing the cartel nope took him in the desert threatening his wife and babies how you expect Walt to act? And in less than one year he took over the meth game that's fukking impressive
Gale dying wasn't Gus' fault, it was Mike's fault for not having Victor watching Gale's place.
Only time Gus really fukked up was not letting his goon off Hector on some pride shyt. Other than that, he was damn near flawless
