elements of a "mind" tragedy
What I found to be the most tragic part of the whole play was the fact that Hamlet put in so much effort and basically drove himself crazy to avenge Claudius, but he never even became king. As he tells the "wretched queen, adieu", one thinks he simply says his last goodbyes (V.ii.365). But on the inside, he is dying at the fact that he never became king. I think he knows it too, that the worst part about fighting for revenge was really getting nothing out of it. All that time and effort he spent had been thrown away in a matter of seconds. The fall of Hamlet, to me, was more important than the fall of Claudius.
