Was Fortinbras right in his statement?

I personally think that Fortibas was partly right and partly not. I say this because if you look at it from one perspective, Hamlet was doing all that he did because he wanted to stay loyal to his father, who was also the royal king,  and take revenge for him, which in those days was perfectly alright. I think that although what Hamlet was doing might have been for a 'good cause', the way he went around things was wrong. His mission was to kill one bad guy and this turned into killing nearly everyone but 2 people. Not only did he's attempt of killing his uncle lead to the death of his girlfriend which he loved although he didn't really show much affection towards, but he's attempt also lead to the death of her father, brother and his own mother. However, the other perspective which you can look at is that all the tragedy deaths was not directly caused by Hamlet but in fact Claudios as the murder he committed was what had all these knock on effects on all the other deaths and therefore Hamlet can be looked at as someone who was trying to do the right thing, a real 'soldier'.

At the end of act 3, Hamlet accidently kills polonious. He is with his mother talking when he spots something moving behind the curtains. As it's his mother's bedroom he assumes that is Claudious and sees this as a chance to kill him as he'd already failed his first attempt. After realising it wasn't Claudious afterall and that it was in fact Polonious, Hamlet shows no remorse and thinks nothing of the fact that he had just committed cold blooded murder. A little bit later, the ghost turns up and Hamlet talks to the ghost; however, the mother cannot see nor hear anyone so thinks that her son is going mad.

In act 4 Hamlet goes and pulls Polonious' body apart. Hamlet is told that he's being sent away to England. Claudious seems to be relieved and feels like he has taken care of the risk of being exposed as a murderer and also of the risk of getting killed by Hamlet as revenge for his father.

Fortanbras arrives with his army seeking revenge on Norway.

Hamlet reads out he's soliloque in page 102 and 103 where he says 'my thoughts be bloody. He is really determined to at last avenge for his father and kill Claudious for all he has done, murdering his father as well as marrying his mother within 2 moths of his father's death; however, he has a porblem: he is being sent away to England.

In scene 5 Ophelia sings. The country want Laertes to be king. He returns to find out his father has been murdered and is after revenge. Ophelia has gone mad understandibly after all that she has been through. The king realises he needs to start thinking on his feet.

I think that Hamlet is upset by he's father death and within 2 months of the death his mother already married his uncle. Already annoyed by the fact his mother moved on quickly, he finds out that he's father was viciously murdered by his uncle. Hamlet feels like he's a coward and is angry at himself for not being able to stand up for his father and take revenge for him as he had promised. He's confused as to how to get back at his uncle and ends up coming up with a plan where he gets actors to act out the murder scene of his father so that he can observe any unusual reactions he's uncle might do. I think Hamlet is being set back because he knows his mother's in love with his uncle and therefore doesn't want to 'break' her heart again as she seems happy.
