Their lack of awareness is what got them killed. Because they did not pay attention to the fact that Hamlet was listening in to their conversation on the boat, Hamlet was able to switch the letter. Because they did not see what Hamlet was doing and connect the dots, they lost the opportunity to save themselves. Guildenstern himself mentions that his ignorance is problematic in his current situation and that it has lead him to confusion which is ultimately why he and Rosencrantz are always last to know what is happening in their environments. Rosencrantz and Guildenstern, as we see them in the play, seem to have been born into isolation. The reader never learns why or how both Rosencrantz and Guildenstern became isolated but because of that, Rosencrantz and Guildenstern don't know anything about themselves and therefore have no other option besides to believe what everyone is telling
