...and her husband would still be alive, if Rick did not let his rod / male, possessive ego drive him toward an unnecessary confrontation which set Pete in motion.
That's just irresponsible. Whether you realize it or not, you've just made an argument to support acquiescence to spousal abuse. "Don't poke the bear, or people could get hurt" You don't put a badge on someone and then tell them "But don't ruffle any feathers", when you're clearly harboring an abusive victimizer in your fold.
Intervention was necessary. No one in ASZ was willing to do so, so that means it would fall to Rick's group to do it, lest they allow an unacceptable situation to fester, and possibly worsen, and his group would NOT do that. Rick, being the leader, was always
going to be a part of the intervention, and regardless, porchdick was never going to listen to anyone of his group, the majority of whom had other problems pending, except Carol, who wouldn't help because she wanted to maintain her facade & Michonne, who Rick questioned her loyalty (Wrongfully imho)
Rick was right to intercede, and though it may have gotten more personal than a cop should get, ultimately Jesse asked for his help, and later she told him he did the right thing.
It's easy sport to come down on Rick for everything, man. He's the LEAD. He's in charge, and he's had the most to lose this whole time. You could say that if he'd just died in a coma then none of this badness would ever have happened, but it's BS to say that circumstantial badness falls on his shoulders. He's the leader of a post-apocalyptic horde, steeped in chaos, not a commander being judged by a military tribunal
I do agree with Kestral about Carol though. I don't come down on her too much either, but it's time now to cut out the literal cloak & dagger shit. At some point, if you're unwilling to put all your cards on the table, then you are not a reliable group member
Shit, when Daryl wouldn't take the gun from her, she even gave HIM a momentary glance of derision, like she couldn't completely put her faith in him. WTF? Daryl is the 1st one I'd put my faith in (Like Aaron apparently) You have to trust somebody sometime, lady. It may come off as cool badassery, but it's also self destructive
