Pippin:
But what if Dumbledore had always planned that Snape would appear
to betray him once Harry was ready to leave Hogwarts? Snape is not
going to be much use hanging around Hogwarts while Harry is off 
hunting for horcruxes, so why not send Snape back to the enemy 
camp as mole and saboteur?

Once it became clear that Harry would not have the acting ability 
or the skill with occlumency to guard the secret of a false betrayal,
Dumbledore could only keep it from him.  But in that case, nurturing 
trust between Snape and Harry would be no use, since it would be 
broken when the 'betrayal' took place.
