How can i improve this paragraph?

There are many reasons for men to kill men, but there are none that have the same place in men’s hearts as revenge. In their foolishness men take it upon themselves to settle their own vendettas. No other piece of literature can better demonstrate the theme of revenge than Shakespeare’s Hamlet. Hamlet, Fortinbras, Laertes, and Old Hamlet put everything on the line for the sake of their revenge, leading to each of their downfalls. The desire for revenge is demonstrated in the play in many instances: by Hamlet, through Hamlets desire for revenge on Claudius, by Laertes craving for revenge on Hamlet, by Fortinbras yearning for revenge on Denmark, and by Old Hamlet's aspiration for revenge on his brother.
