Machiavellianism in Richard III.

Examine Machiavellianism in Richard III. How do the title characters embody the philosophy outlined in The Prince? What does his success or failure tell us about Shakespeare’s attitude toward this philosophy and statecraft in general? Beware simplistic readings, however. Just because Richard is Machiavellian and he fails does not necessarily means Shakespeare finds all his methods repulsive. Cite specifics from both Richard III and The Prince.
