Answer:
A critical essay is an academic text that we write to make an analysis or evaluation of a text, in this case by Hamlet.
It does not mean that we are going to criticize the work giving personal opinions, but that we are going to analyze its themes or the way it was written.
Step-by-step explanation:
In this critical essay we are going to analyze one of the several themes that Hamlet has: revenge.
In Hamlet's heart the desire for revenge predominated, but could this bring any benefit? Probably not, however for Hamlet it was indispensable to avenge his father's death because of the promise he made to him.
This internal struggle between "good and evil" made Hamlet begin to develop symptoms of madness. He began to doubt his friends and family, and even told Ofelia that he did not love her.
Hence, Hamlet's great doubt arises: to be or not to be.
Eventually Hamlet ends up taking revenge on his uncle Claudius, but his hatred and revenge ends with everyone's death.
In this way the usefulness of revenge is questioned, even if it is motivated.
