I think that's an interesting theory you bring up. That maybe Spike will be the actual Big Bad. So he's crazy now and seeing all these baddies that are telling him to do things...
The only problem with that is when he says he tried to cut his heart out. That says to me he's being driven crazy by feeling the guilt and pain of what he did as a vamp. So that makes me less inclined to think he could be the bad guy.
