Rick is too used to people blindly following him.
That was a good thing out in the wilderness. You need decisive leadership. Someone to take control and people to follow orders.
In civilisation it doesn't work as well, especially when you are trying to integrate with another group with a benevolent dictator.
Effectively they are trying to merge two dictatorships.
Who is going to trust him now? The only people that matter lol. His group will trust him. Rick's long term plan is to live in Alexandria. The problem is the alexandrians ineptitude isn't just putting those idiots in danger but it's putting his whole group in danger. They already lost Noah due to it. What if some shit ACTUALLY popped off? It could be a lot worse. They don't know what they're doing. They've been sheltered and got lucky. They're actually lucky that someone like Rick is the one to go crazy on them rather than the claimers or the governor or whatever else is out there.
Rick has good intentions in the end. And more importantly, Rick delivers results. Everyone else is all talk. He knows that though. He knew he was going to be the asshole of the group the second he gave his ricktatorship speech.
Like I said before, everyone else is a hypocrite. They like to think they haven't become as crazy as him but the SECOND something pops off they're all willing to lean on the dude to get them out of a mess.
All of these things could have been avoided with persuasion and consensus. All he has done now is fuck things up. This was probably the stupidest way of dealing with the conflicting world views.
He also choose this issue - the wife beater - for the wrong reasons. Something he admitted:
"Would you do this for someone else?"
"No"
He is thinking with his dick when he needs to be thinking with his head. He has escalated something that could have been avoided. People will die because of this.
I like Rick and I think he's bee doing what needs to be done, mostly, but maybe he isn't the right person for this process.
And the senator isn't much better. Ignoring the wife beater because they can't think what to do with him and because they need him. Fuck that's cold.
