How does Hamlet treat Guildenstern after the play has ended?

At the end of Hamlet, both Hamlet and Guildenstern are dead. Hamlet has died in a fight with Laertes, when Claudius had put poison on Laertes' sword. Guildenstern died at Hamlet's hand. Claudius had written a letter instructing people to kill Hamlet, but Hamlet was able to rewrite it so that it was condemning Rosencrantz and Guildenstern to death instead of himself.
