i don't think he is really either (we did this kind of thing recently in english), i think he is the herald in the Cambellian hero cycle (please tell me someone else has heard of that because otherwise i feel really awkward). as my English teacher explained it, the matrix movies follow an almost perfect Cambellian hero cycle and in the cycle (which is like a general format for most stories/movies that sems to be irresistable to mosy people) and in the cycle there is a person called the herald (morphieus) who takes the hero (neo) out of his relativly safe place. and that is exactly what he did with the pills.
