Putting on their shoes is a great comment, now think of it this way, what civilization are you all talking about? The one we live in now? The one that should not be foresaken because of our current understanding of what civilization is?
Personally I don't condone the way Rick pulled a gun out and waved it at the other people, but, I can understand why.
The rules/laws of the previous civilization does not exist anymore, BUT, they should change for the circumstances that
are there. Deanna is living in a dreamworld for now, BUT, it does NOT mean that it is the end.
As for the mentality of other people, how they are protrayed as losing a part of themselves comes from their understanding
of what civilization meant [past tense] before... they had a glimpse of it while being in the Prison, then it was taken away
from them, then there were the cannabilistic group they encountered, where their hopes got destroyed... now this, something
that resembles a chance... what else is going to happen? Shit, I would lose my mind also...

I can understand a lot of what people are posting, but, I think Carol is a bit more lost in the head than Rick, she is the one
actually manipulating Rick by her comments.
