Hamlet's obsesstion with death. How his thoughts on death change throughout the play.

Hey, I was just wondering if someone could help me edit or revise my thesis statement on Hamlet.
Thanks.

In the course of the play, Hamlet's perception of death of is significantly altered, from his purposeful menacing, to his absorbing obsession, towards a calm, emotionless murderer.

It is a little awkward. The perception does not become a murderer...
Do this:
In the course of the play, Hamlet's perception of death of is significantly altered; he changes from a purpose-oriented menace into a person absorbed and obsessed with death, and finally he becomes a calm, emotionless murderer.

Do you like it this way?

Now that you observed something rather obvious, add one more short sentence to draw an ARGUABLE conclusion. Add more more sentence to add definition to what you are doing. Make a creative argument about why this progression occurs.
