It’s true that Rick is a Class A dolt for ever believing Jadis in the first place, but she doesn’t deserve to continue taking shit from people after double-crossing Team Family, even if she justifiably got dicked over by Negan.

It’s absolutely possible some of those Scavenger folks aren’t wholly deserving of getting sent to that car-lined junkyard in the sky, most of them are, and the one with the biggest Target shopping bag on her head is the group’s leader Jadis, a less-than-expert at small talk and keeping promises.
