Seriously... what the hell was Jesus doing there? And didn't Darryl just show the same mercy to Dwight that Rick did? If he had just killed Dwight... okay, I get it. But they let him have his arc, he moved on from Dwight and reciprocity killing... and then mysteriously appears from the shadows as if to say: Remember my last scene? JUST KIDDING!
in his defense... Daryl has always been a softy... he told dwight to go find his wife.... very possible that he transferred Dwights sins over to Negan since he was the puppet master for the saviors.
it was a semi interesting play on emotions, closure, atonement. Rick only allowed Negan to live because of Carl....Eugene sabotaged the ammo because of Abraham.... Maggie and Daryl both want Negan dead because of Glenn.
I think they are going to set Negan up...an obscure opportunity to escape and acquire a weapon...give Negan an opportunity to expose himself and show Rick he is too much a threat to keep alive.
In a weird way... I think the throat slashing was a symbolic kill for Rick... he cut his throat, so the part of him that wanted revenge can rest,... but he let negan live, so the part of him that wants to honor his sons memory can survive and be satisfied.
Lots of debate in regards to leadership style. Killing Negan may have martyred him to some of his guys....thus making them more dangerous to the attempt at a civilized society.... there is a small danger that some of his followers may try to free him,... but he didnt rule by love and respect...so that is a slim risk..
oddly, in some ways seeing Negan killed may have actually provided some of the saviors with closure as well. they dont have to try and sleep at night wondering if he will wake them and punish them for their betrayal.
remember that blonde chick that snitched off Dwight. She was away..free of the saviors.. but she found her way back so she could snitch off Dwight. Factor in some social psyche factors...Negan treated her as equal with the men....then maybe a little battered woman syndrome... she is likely to be a threat to "rescue" Negan in the future... that arc could be assisted if she is not made to feel safe right away by the new group.
I dont see Maggie and Daryl flat out turning against Rick...tying up he and Michonne and running a lynch mob on Negan... they want Rick to make the decision that Negan has to die.... Negan being killed was the primary objective of the war for them anyway and they always thought Rick was on board.
