Humans are bizarre creatures. Through the ages, we have established a set of rules regarding “good” and “bad”. No matter how abstractthose ideas are, we have done our best to come to an agreement of what is okay, and what just doesn’t fly. Love is great, but loving someone so much that you follow them everywhere they go is considered rather creepy. Being ambitious is also something our society considers good, but once you go over corpses it’s a completely different story. We do our best to enforce these ideas on every member of our society, and yet the people from fiction who defy these ideas are the ones that fascinate us the most.
Take exhibit A, Heath Ledger’s potrayal of the Joker in The Dark Knight Rises. Actually, just take any portrayal of the Joker. One of Batman’s most famous enemies is everything we as a society despise: he is chaos incarnate, and a sociopath to boot. He blows up hospitals just because he wants to lure out a single caped crusader, and burns mountains of money just to “send a message”. He even treats his greatest fan like shit, caring nothing for her emotions. The Joker does steps and spits on our moral and ethic codes, and then sets them on fire. And still, we deem him to be one of the greatest fictional characters ever.
