na they cleaned out the baddies
beth killed the rapist
the one beth pushed off the elevator was implied to be bad, only clues we have is that he bullied some old guy and dawn mentioning that he laughed about the girl getting raped
the one rick killed was probably good and so are the ones still alive, although dude was an idiot for running. running initially is a good idea since like he said, he doesnt know whether rick's group is bad or good. but rick gave him a chance to stop once he caught up to him, at which point he can either die running away (the option he chose), or take a gamble, stop and possibly live
the remaining were good since the girl cop who was taken hostage tried to speak up against dawn when she tried to change the deal and ask for noah back
also if they were bad, they would've had a full blown shootout in that hallway
plus when rick offered others to leave, none did....at that moment i think both groups knew that each other were good as they offered to each other assistance
beth stabbed dawn because she also lost "it", dawn explained to beth that she had to kill the previous leader, her mentor because he lost sight of wat it was to lead or w/e, don't remember 100%
but that scene was basically setting up for beth to kill dawn because in a way dawn became beth's mentor and just as dawn killed her mentor, beth now kills dawn, since beth now realizes too that dawn has lost her way (though she failed and daryl had to finish dawn off)
