Characters they can't kill off

At least shouldn't in our opinions.. At this point, I have to say I don't want any member of the main group to die; Daryl, Carol, Hershel, Glenn! Rick, Maggie, everyone else.. but it is a show (and comic series) where characters we have grown attached to have died, so I wouldn't be surprised if eventually they do die (won't stop me from being sad of course) .. although I don't think I would mind losing Andrea, and I'd rather see Carl go instead of watching him go completely over to the dark side. Do you guys feel the same way?
