What are the weaknesses of each hero in Shakespeare's greatest tragedies?

Each hero in Shakespeare's four greatest tragedies has his weakness of nature:
Hamlet faces the dilemma between action and mind; Othello's inner weakness is made use of by the outside evil force, the old king Lear who is unwilling to totally give up his power to make himself suffer from treachery and infidelity; and Macbeth's lust for power stirs up his ambition and leads him to incessant crimes. .
