Approval or Disapproval?

Approval. Horatio seemed to be happy that Rosencrantz and Guildenstern were being sent to die. He might also be proud that it was Hamlet who lead them to their graves. After all, they were to lead Hamlet to his death in England. They may have been friends but because of the promise of money, they are now sponges. Also, Horatio probably thought very little about R and G due to the fact that they were barely around anyways. It was not like they made a difference. They were there because they were needed. That was all.
