Please compare Hamlet's soliloquy at the end of act 4, scene 4 with act 2, scene 2.

The tone of 'sat the end of act 2, scene 2 is frantic. He is desperate to uncover the
truth about : "If he but blench, / I know my course." He is distraught that a mere
actor can bring tears to his eyes over the imagined actions of Hecuba, andsees himself by
comparison as dull and hesitant, seeming to be an actor in someone else's life.

Hamlet is pretty self-loathing in this speech, referring to himself as a
villian, a slave, hesitant, a
coward, an an ass. He feels simultaneously compelled
to act on behalf of his father's murder and unsure if he has the courage to do what is needed to
uncover the truth and then act on it. By the end of this soliloquy, he bolsters up his resolve
for action: "I'll have grounds / More relative than this. The play's the thing / Wherein
I'll catch the conscience of the king."

In act 4, scene 4, Hamlet has
emerged as a more steady voice. Here, he feels confident that "all occasions do inform
against [him] / And spur [his] dull revenge."...
