Hamlet as a prime example of a tragedy?

I. A. Richards writes "suppression and sublimation alike are devices by which we endeavor to avoid issues which might bewilder us. The essence of Tragedy is that it forces us to live for a moment without them."

Consider Shakespeare's Hamlet: it has a ghost who prowls through the castle's environment, a dastardly villain who has poisoned his brother in a terrible manner (poison into the ear!), a young fair maiden who is spurned, goes mad, and tragically does herself in. Not to mention the spies, the intrigue, subplots and counter-plots. Then there is young prince Hamlet, an intelligent soulful youngster, bent on revenge, who talks to a human skull. It all ends in bloody subterfuge, with a dramatic sword-fight, more poisons and multiple body count on stage.

Then again, is it a Tragedy, in the sense Richards sees a work to be?
