King Claudius

On the surface he seems to be a good King capable of dealing with the politic issues of war.

He has clearly killed King Hamlet to get the throne for himself and gradually his guilt becomes more obvious to the audience.

He covers up his true actions.

He must love Gertrude to have married her.

He genuinely seems to want Hamlet to get over the death of his father and has his best interests at heart.

He spies on Hamlet and plans to murder him to cover up his own evil actions.

He confesses his sins in the chapel so we are sure of his guilt.

He seems to have a conscience and seems sorry for what he has done, but this does not stop him from trying to kill Hamlet and keeping the throne.

Claudius’s plot to kill Hamlet fails and he dies at the hands of his own poison.
