Why doesnt He Act sOONER? -Jo

I am thinking about writing about why it took so long for Hamlet to do anyhing. He was already mad in the beginning of the play when his uncle takes the place of his beloved father and soon after he finds out via the ghost that Claudius was the one who muredered his father through a premeditated death. why didnt he simply revenge right away? Why was it such a long process and why did he let other aspects of his life, become such problems? was his insanity only because his father. I want to write about all the events which lead up to the death of them all and how the play switched roles and the last scene was not in Hamlets plan to kill Claudius, but Claudiuss to kill Hamlet. Was there something that prevented him from acting as soon as he knew? Because it would not have been a tragedy if only one more man died, the one who rightiuosly deserved to because he killed his father, a good and honest king. I will use primarily the speech, on page 117, 167 and 203. aLL three are examples of how Hamlet wants to kill but overthinks himself, (which is also Shakespear) the writer really shining through...... because the play was a tragedy to work out and for no one to be happy. Im not sure what my thesis or main theme should be tho.,.. any advice? thanks
