I think at this point everyone is trying to show their worth, and that's why Dale is trying to hard to play mechanic (in the beginning), peacemaker, psychologist, and philosopher. He's old, and he has to be thinking what his value is in such violent times. For the audience I believe he plays the role of the observer/audience. In a world gone mad, we see it through his eyes.

Rick the the leader, Shane is the enforcer, Daryl is the hunter, Glenn is the courier, the chick is the sharp shooter, Dale is the sage, Rick's wife is the village slut, and T-Dogg is the... he's the... um... the next victim (hopefully).
