Hamlet

In Hamlet's soliloquies, are his assessments of his problems accurate? Are his assessments of others' behaviors accurate? Examples??

To answer this question, I need to first identify the main soliloquies to examine.  I will look at Act 1, sc. 2, Act 2, sc. 2, Act 3, sc.1, and Act 4, sc. 4.  In the first of these soliloquies, Hamlet laments the fact that his father died and his mother remarried so quickly, and married his uncle.  He correctly recognizes that there is something not quite right in this action, though he has no idea what it is that isn't right. In the next soliloquy, he is angry with himself for not having done what his father's ghost asked him to do.  He questions his bravery and his ability to do what's asked of him. He, again, is accurate in assessing his problem here, namely, lack of action. In the third soliloquy, Hamlet again laments his lot in life. Like the first soliloquy, he mentions that suicide would be an option if it weren't for the fact that it is a sin.  He says that fear of death makes people (himself) cowardly. He says he is overthinking matters.  That is a very accurate assessment.  In the last soliloquy, Hamlet marvels at how Fortinbras is so fast and sure acting.  Fortinbras is working to get back the land his father lost to Hamlet's father. He sees that he must finally act on the promise he made to his father's ghost or lose all honor. He realizes he is too slow-acting and that he overthinks his problems. Again, he sees his problem clearly.  He seems to accurately understand Fortinbras's motivation as well.
