Honestly, Ezekiel deserves credit just for agreeing to harbor Daryl.
Why would Ezekiel want to form an alliance with a community that just had two of their members brutally murdered when The Kingdom is getting by without bloodshed?
The midseason premiere revealed that the Saviors are on the hunt for Daryl and won’t be giving up anytime soon; Ezekiel could get his community in a lot of trouble if the Saviors discover that Daryl has sanctuary with them.
As much as we should root for Ezekiel to join Rick and the other good guys in taking down Negan, the good king has a point about why The Kingdom is better off continuing their deal with the Saviors than rebelling against them.
