Act 1, Sc. 3-5

When my dead father's spirit told me that he was murdered, I went crazy of fury. I knew it was my uncle Claudius. I promised my father that my loyalty and my honor toward him would be shown by the blood of my sword, Claudius will die.

Also, the dark marriage of my mother with my uncle, was too much for my tolerance and patience. My revenge had to showed up, and to save my vulnerable mother from that poisonous human being, Claudius.
