“Some men aren’t looking for anything logical like money. They can’t be bought, bullied, reasoned or negotiated with. Some men just want to watch the world burn.” -Alfred in The Dark Knight
Ah, the infinite wisdom of Alfred. I dare to say that he is one of the wisest characters in recent memory. Many pieces of dialogue from Bruce’s surrogate father figure could have qualified for this list, but this was definitely the pinnacle of Alfred quotes.
Simply put, it just captures the essence of the Joker so well. There is no method to his madness. There is only a madness to his madness. That is what makes him such a formidable foe for Batman. If there was a motive Batman could discover, he would then know his enemy and know how to defeat him. With the Joker though, there is no information to learn other than he can’t be understood. He simply wants to watch the world burn.
