The Tragedy of Hamlet, Prince of Denmark, raises a fundamental question of how Shakespeare intends his readers to regard the ethics of revenge. The moral angle of the story is unavoidable, for it underlies the question—Is Hamlet predicated on the assumption that the Ghost’s command is morally binding? Regarding this matter, most critics still hold that the average Elizabethan believed a son morally bound to revenge his father’s death. However, the view on revenge, being that of the average Elizabethan, is a case to case basis, for the average spectator at a revenge play was probably trapped in an ethical dilemma—a dilemma, to put it most simply, between what he believed and what he felt.

What are Hamlet's most notable character traits
Hamlet marks a sufficient break in Shakespeare’s career as to suggest some more personal cause for his daring transformation both of his sources and of his whole way of writing. A simple index of this transformation is the astonishing rush of new words, words that he had never used before in some twenty-one plays and in two long poems. There are, scholars have calculated, more than six hundred of these words, many of them not only new to Shakespeare but also—compulsive, fanged, besmirch, intruding, overgrowth, pander, outbreak, unfledged, unimproved, unnerved, unpolluted, unweeded, to name only a few—new to the written record of the English language. Something must have been at work in Shakespeare, something powerful enough to call forth this linguistic explosion. As audiences and readers have long instinctively understood, passionate grief, provoked by the death of a loved one, lies at the heart of Shakespeare’s tragedy. Even if the decision to redo the old tragedy of Hamlet had come to Shakespeare from strictly commercial considerations, the coincidence of the names—the writing again and again of the name of his dead son as he composed the play—may have reopened a deep wound, a wound that had never properly healed.
