What is hamlet's attitude towards claudius?

Hamlet is entirely vengeful towards his uncle , Claudius. He feels that Claudius is responsible for his father's death and when this is revealed to be true, his revenge is set into action. The entire play recounts how Hamlet exacts his revenge on his uncle. Claudius killed Hamlet's father, married his mother and took the place of king. This overwhelming grief that Hamlet first experiences then turns to rage and all in all is responsible for his own madness in the end. Hamlet is a great display of moral corruption.
