I cannot see them being any different than their adversaries, since most of the core group is on or crossing that border right now. With that, I see Morgan, Carol and careful fence-sitter Michonne all dying or leaving thanks to the increasingly nihilistic platform of the group.
The approach of Hershel, Beth, Tyreese and Dale is as dead as they are.
I'd say in a world like this, where killing for survival is part of a new norm, Rick and his group still fall on the side of "good."
We've yet to see Rick's group kill for a direct, personal, gain. If Rick or members of his group came across another, "civilized" group of survivors on the road they wouldn't stop them and say, "Give us all of your stuff, show us where you live, and one of you will likely die."
They didn't go into the Hilltop with the goal or aim of taking the place over or cleaning them out, they went there to set-up a formal relationship. Rick does say, "we're not leaving empty-handed" but it's highly unlikely he means "deal with us or we'll take it" and he's just using some measure of "tough negotiations."
Given the problems they've had with Woodbury/The Governor, The Claimers, Terminus/The Termites, The Wolves and now The Saviors it's understandable to realize that this was an encounter that had to happen sooner or later and going with a covert
coup d'etat to minimize personal risk than to have a more active encounter when The Saviors eventually found them. Without the RPG the encounter between Daryl, Sasha and Abraham and The Saviors would have ended differently and very badly for The Alexandrians.
They've little reason to distrust Jesus and he's the reason why the know the story of The Hilltop and Saviors, what happened and Gregory was hardly acting as someone dishonest, especially after the attack, it also matches up with Daryl's encounter on the road with the biker Saviors.
So, I think we can unobjectively say that our group are still the "good" guys. Accepting this is a dog-eat-dog world where even good guys have to kill, even when unprovoked or attacked or as extreme retaliation for an attack.
Our group is killing for their protection.
The Saviors were killing in order to "tax" other groups for their food and supplies. They took half of Hilltop's supplies for a "protection payment" and continued to demand subsequent payments, apparently, in increasing numbers and failure to meet demands was met with death.
So, again i say, our group still falls on the side of "good." They kill for protection and long-term survival. They do not kill for gain of goods and property. Were that the case they would have overpowered The Governor and seized Woodbury, or done that to The Hilltop, they had the weapons and experience to take Hilltop quickly and they chose not to.
I find it astonishingly how easy some want to say our group is falling on the "bad" side or are losing their claim to being "good guys." When they've yet to kill for a direct, personal, gain.
