About the clown in Heath Ledger.

Heath Ledger's clown is pure evil in this evil world, just like Wayne's transformation into Batman is pure kindness in his heart.

Therefore, the clown's sin is due to his extreme despair of the world. This despair made him complete the transformation and became the ultimate criminal who lived by sin. It is Heath Ledger's top performance that adds a lot of color to this work. Heath Ledger won the Oscar for Best Supporting Actor for this role.
