In what ways is Hamlet heroic in Shakespeare's play Hamlet?

In his
criticism of , renowned critic Harold Bloom writes,

No other single character in the plays, not even Falstaff or
Cleopatra, matches 's infinite reverberations.

Perhaps it
is because of these "reverberations," the tremendous scope of Hamlet's character as he
echoes so many human traits, that raises the question of his heroism. For, Elsinore is too small
a "mousetrap" for one so grand and charismatic as Hamlet, except for the fact that he
returns to it voluntarily.  And, thus he is the tragic hero, for like his counterpoint, , Hamlet
chooses to avenge his father's honor and sacrifices his life in the heroic effort.

Rightly to be great 
Is not to stir without great
argument, 
But greatly to find quarrel in a straw 
When honour's at the stake.
How stand I then, 
That have a father kill'd, a mother stain'd,...  
And let
all sleep, while to my shame I see 
The imminent death of twenty thousand
men...  
Go to their graves like beds, fight for a plot....(4.4.55-64)
