Answer:
"What if this cursed hand
Were thicker than itself with brother's blood
Is there not rain enough in the sweet heavens
To wash it white as snow?"
In this excerpt, we can see that Claudius fears his own fate. He confesses to the murder of his brother ("with brother's blood"), and realizes that this makes him a cursed man ("this cursed hand"). He also wonders if there is something in the world that could possibly help him redeem himself ("Is there not rain enough in the sweet heavens/To wash it white as snow?"). He desires to be cleansed of his sin, but believes it impossible, which worries him greatly.
