Why does Hamlet dilly-dally in avenging the murder of his father? His father’s ghost clearly exhorts him to do it. He knows it is his duty and he must do it though he does not like it.
“… O cursed spite
That ever I was born to set it right.”
Taking his cue from these lines, Goethe observes, “A beautiful, pure and most moral nature, without the strength of nerve which makes a hero, sinks beneath a burden which it can neither bear nor throw off; every duty is holy to him- this too hard. The impossible is required of him- not the impossible in itself, but impossible to him.”
