R&G

I don't really fully understand the difference between disapproval and approval on this. I think like does Horatio agree or disagree with what Hamlets saying is what it means? I think Horatio is agreeing or approving because when he say "go to it" it seems like he's just brushing R&G aside. Like this is just another task that they are sent out to complete, it just happens to be their death. Their no longer useful to the story, so he's just dissmissing them from the play.
