Sam, Roberto, Izzy, Hyperion don't seem dark or divided at all. I'd say the newer heroes Avengers are proving to be more effective than the veterans who all have heavy baggage to contend with stretching from things years back way before Hickman was involved. I'd argue that's a theme to the story.
That being said I'm keeping proverbial money on the idea the vets will claw it back in the end. It wont be cut and dry but it's been the way that heroes who don't don't always get along or like each other or even want to be heroes since Marvel established their house style in the sixties.
