Hard to know. I think they were still going to kill one of them. Our red head has killed 10+ people herself and they intimidate other groups (not all of the Hilltop folks are dead), so if they have ladies (not the bikers who do runs/have a lot of conflicts) with 10+ kills they are bad people. Lunger seemed to have the exact same philosophy as Red, so to her a big show might be the speeches and that killing people is just part of the show, no big deal.
I think they are trying to sow some seeds of doubt that our crew may be the bad guys, but I have a feeling they will dispel that when we see Negan.
ETA: I don't think our group is necessarily "all good" because all good people get killed in this world, but I do think they would live and let live to people that just wanted to trade with them. IMHO, Carol <> Red. They've both killed a lot of people, but I think for different reasons. They'd rather not kill people whereas I think Negan's crew could care less about killing people to get stuff they want to take.
