Q1- Was society to blame for Willys death? Q2- How is the American dream reflected in the play? Q3- What role did Biff play in helping or stopping his father committing suicide?

I think Willy's death can be attributed to a number of factors. The illusion of the American Dream is just one of them. I think Miller was really drying to deconstruct the American dream through Willy. As readers, we quickly understand that Willy's version of the American dream is largely an illusion. Success, simply for its own sake, becomes a self-fulfilling failure. Willy wants his success quickly and easily without passion or pride. The spoils of his "success" never materialize. As Willie's illusion disintegrates, so does his identity built on that illusion.
