You Are A Tooooooy!!!
Whatshisname from the Kingdom totally didn't deserve to die. Morgan breaks his no kill rule (for the second time) over that? The only way I find that acceptable is if Morgan felt he was going to instigate the fight at a critically wrong time (which it may have been - I feel like they'd be best co-ordinating with Alexandria and Hilltop before they make any move). Otherwise whatshisname had sound intentions - he was willing to make himself the sacrificial lamb - and he had every reason to believe that's exactly how it would go, it just didn't.
Its exactly how it went down. He sad we have to make them trust us again then we kill them. He did make himself the "sacrificial lamb" to gain that trust to then kill them later. Everything he told Morgan that needed to happen did happen.
