I, his sole son, do this same villain send to heaven.
In act 3 scene 1, Hamlet and Ophelia have a conversation and he tells her that hes never loved her and that isn't the reason he's going mad. He insults her and tells her to go to a nunnery. Polonius and Claudius plan to send him to England
In scene 3 act 2, during the play, Claudius gets up and leaves which proves top Hamlet that the ghost was telling the truth and now he can avenge his fathers death and go and confront his mother about her actions.
In act 3 scene 3, Hamlet walks in on Claudius praying and Hamlet is thinking he wants to kill him but not at this moment because if he does while he's praying, Claudius will be sent to heaven which is unfair to Hamlet bc his father didn't get that option.
