Gus has always come off as refusing to change anything because it would be too much effort. I mean, he repeatedly joked that retirement for him was a shotgun.He sold it to a guy who didn't know how to eat edamame.
Though I would agree with that statement, he spent two years letting everyone know the ships sinking and he was leaving the fucking country to get away from the shit show he left them with.
Which is funny, as I always pictured Gus being the one to GTFO first.
