My mother is hooked on this show so we have discussions... We were discussing groups in particular that survive, and I was giving her examples of "********" in other similar stories...
Bikers in Dawn of the Dead.
Soldiers in 28 Days Later... That type of stuff.
People well armed, "strong" in numbers, who are mobile, and when societal breakdowns occur, they become free-thinking/independant, and have nobody to answer to any longer, so they become the ******** of the world... Gangs would be included in that ultimately, even though the Vatos would be doing a good thing. They still clearly were willing to harm/hurt people they didn't know to keep doing what they wanted.
Much like Shane, they'd have a duality to them... Shane, as bad as he is, was still doing what he felt was right... He didn't know Otis, and Otis caused Rick's son's injuries, so he figured "F it" and used him to advance himself and who he cares about... Much like his little fit at the barn harmed Hershel, but why would Shane care ya know? Till of course teh zombie that comes out is someone you know, and you care about...
I'm hopeful Webisodes maybe cover some of the more detailed things the Deadophiles want to know like how it started and stuff... I liked the webisode about the half-lady in the park, and I'd love one that focused on Sophia's bite/explanation, and one about the breakdown of society and how it all began and escalated on a national and global scale...
It makes one wonder too, are there isolated places where this isn't affecting anyone? Like could Hawaii be spared because they lock it down or something when they see it out of control or something? Be cool if there were these island havens.
I just love this show... I can't bring myself to read the comics because the show keeps me so tense, I would hate "knowing" the possible future of it at this point.
And don't tease me about these horrible groups of survivors. I really have already imagined a lot, and that just makes me even more giddy for future episodes!

I love this show.
