Morgan

I'm interested what y'all think of Morgan.

His holier-than-thou self-righteous in late season5/season 6 when he returns doesn't make sense. I get how he got there, why I was like that, but when he spared those two Wolves and then saw them when Alexandria was invaded, I figured that would snap him out of the not-killing mindset. He clearly saw that because he didn't kill them, all those people in Alexandria died. The butterfly effect. That was a theme at that point in the show, the whole killing someone who is dangerous/might be dangerous vs. letting them live/exile them.

So, what are your thoughts? Does it make sense to you that Morgan kept that one Wolf hostage in Alexandria and refused to kill him for as long as he did?
