DC and Marvel have always played on a series of tropes that define their characters for readers and movie audiences alike. However, one of the most famous tropes has been responsible for the ongoing decline of compelling villains. In recent years, fans have sparked a debate over what they want to see in their villains. The choices have ranged from Machiavellian rulers to cartoonish, Saturday-morning villainy like Skeletor and Megatron. However, one that causes the most division between fans is the idea of the sympathetic villain, characters driven to crime through necessity and tragedy rather than evil.
