Coo Coo or Cool?

Hamlet is going a little crazy with this whole thing. I feel bad for the boy. I want him to get his revenge and all, but not if it costs him his sanity! I can't really tell whether he's pretending or not anymore. The scariest part of all his coo coo rantings is that they really make sense. It's like his true emotions don't even show anymore unless he's acting crazy. I'm beginning to wonder how he will come out of this state of mind once he's gotten that scum bag to admit to my murder. Or will he?
