How can you give the villain the heart of a hero?

To give a villain the heart of a hero, explore their backstory to reveal trauma or motivations that elicit sympathy. Showcase moments of vulnerability or moral conflict that highlight their struggle between their darker impulses and a desire for redemption. Additionally, allow them to perform acts of selflessness or bravery that align with heroic ideals, creating a complex character who grApples with their identity. This nuanced portrayal can engage the audience's empathy and challenge traditional notions of good and evil.
