We should check to see if they were buried alive??

If I was given the chance to be a participant and the ability to change the plot line in Poe's short story in "Fall in the House of Usher", I would have made Roderick Usher go and try see if his sister was still alive.

Roderick Usher had said he was crazy and hearing voices did not help with his sanity.

What would have happened if Roderick Usher had gone down to the underground tomb to see if his suspicions were true? Maybe Roderick Usher would not have died out of fear and shock as his sister was running towards him.
