So this is one of the ways this season TWD is far better than Fear..some true debate, and characters where we can understand multiple (and conflicting) points of view. Good stuff. Thought Provoking
My view is that, as crazy as the Wolves are, and the limited info we do know, there is always more you can learn. With them being crazy (as opposed to a disciplined kind of evil), it could be easy for some truth to slip out. Perhaps direction, distance, numbers, philosophy (i.e. going out in packs) , whatever.
We also know from at least Woodbury, that good people could get wrapped up with every bad (or , say, Darryl with the claimers).
In that timeframe, it wasn't always obvious who's who. The guy with the axe, and the one chopping up limbs, sure. But you never know.
And as someone said...they don't have to be prisoner forever...just at least a few hours. Rather than waste time, attention & bullets on a secured prisoner, go after the Free Wolves that are an imminent danger, and THEN shoot the prisoner, if needed.
Carol was acting in character, but as before, it might not always have been the right call. (Wrong on the prison virus, right on Terminus). I think Morgan's words -- that she doesn't like doing this, is a legitimate concern. Enjoying it crosses the line.
I also vote that I think Morgan did wind up killing the Wolf, based on what he says. That really hurts him, and I hope that means he'll make a decision to move on (as opposed to getting killed, which happens to most moral compasses on the show)
