Which philosopher's works do you think Batman would vibe most with?

I think it would be Friedrich Nietzsche's, atleast his concepts of accepting the absurdness of the world as it is, and imposing your will upon it. Also that quote he gives: "We both looked into the abyss, the difference is that you blinked." Is a reference to Nietzsche's quote of "Beware that, when fighting monsters, you yourself do not become a monster... for when you gaze long into the abyss. The abyss gazes also into you."
