The thing is, our group always tried to follow the good path within the hell they walked in. But last season changed all that. Maggie made a deal, and the group backed her, to go execute Negan's men in their sleep. Stone cold executions. Rick's group is already well on its way to Negan territory, they just don't revel in brutality quite yet.
Now that they've been broken and had so much taken away, that brutality, hatred, and bloodthirst for revenge is going to come. Maybe y'all want to root for depraved killers, but even there, what's left to say about their emotional journey? They're close to the end of it. They can't come back from this. So there's no story left to tell that has any meaning for the characters.
