What does Claudius reveal in his soliloquy in act 3, scene 3 of Hamlet?

has spent much of the play thus far trying to determine whether to believeclaiming to be his
father who has made claims thatmurdered him.

In this , Claudius confesses
everything, andis within earshot. He feels intense guilt for his crimes and ponders
aloud,

What if this curs¨d hand
Were thicker
than itself with brothers blood?
Is there not rain enough in the sweet
heavens
To wash it white as snow. (III.iii.46-49)

Hamlet has his answer. Claudius's hands are covered in his brother's (who is therefore
Hamlet's father) bloodand he questions whether heaven can wash these sins "white as
snow" or if he can possibly be forgiven since he still retains all that he gained by
committing the murder. His confession further acknowledges his motives:

I am still possessed
Of those effects for which I did the
murder:
My crown, mine own ambition, and my queen. (III.iii.56-58)

Claudius wanted the crown, wanted Queenas his own, and sought to
fulfill his own ambition...
