Insanity, the sole road to preserving self dignity?

Insanity, Could it have been the only way without people discriminating Hamlet's respect as a prince? Hamlet a bright and sane man, only claimed madness to have the ability to say and perform actions that he otherwise would be prohibited from. I feel that as a person of his power he played his cards correct without a doubt. You cannot just jump out as a sane man and begin pointing fingers towards every individual without proof. Hamlet had no proof he had to make his own proof. His Only witness was dead and it was not like others could even see it. Insanity was the only way to allow Hamlet to distinctively learn more about King Claudius' personality and to find out more about who he really is. Insanity preserved Hamlet's respect as a prince.
