Said with approval?

Horatio tells Hamlet in line 56: "so Rosencrantz and Guildenstern go to it." In this line of text i gathered that he is neither saying it with approval or dissaproval. He is only stating it as a fact. There is no context that proves that his mood is either sorrow or recognition. He is stating it, neither defining whether it is a bad or good thing. It is as if he has lost all emotion within himself and disconnected from the dissolussioned world around him. It almost seems robot-like in the way he says it. It is mysteriously nonchalant. I think that he finally realized that everyone around him was all tied to Hamlet and that everything was inevitable, even the deaths of Rosencrantz and Guildenstern. There was absolutely nothing that he could do to make the situation any better. Therefore, I feel that it is a much needed statement which clearly defines the indifferent attitude of Horatio.
