Batman and the Joker.
Who is really delusional?

The one who believes that...well, what does Batman believe in anyway? Justice? Revenge? Maybe nothing? To have rules...to not kill his enemies? Belief that there is good in this world...in people? Belief in a deeper and greater something among people? Whatever it is, it's reflected in his behavior to some extent. Delusional?

Or...the Joker? who believes in chaos in the world, that underlying the brittle social structure set up by people or other living things, there is no real meaning? No real justification for anything? If that's what he believes...or perhaps he doesn't believe in that....maybe believes in nothing...or just doesn't believe in some particular thing that makes society tick.

Batman vs the Joker...and with guys like 2-face who apparently even becomes this other alter-ego called, i think, the Judge, walking around with a judge-like hammer but in sledgehammer form....is really a interesting look into...what would this be...philosophy?

Is courage noble but stupid? If you calculate and odds are in your favor to the degree that you are comfortable, are you still brave for going ahead? If odds aren't good enough and you still go ahead for perhaps the ideal of a greater purposes or something...is that just stupidity, pure risk-taking? Or does that moment of bravery actually cause your odds to go up?
Is hope also just a drug? Is religion a drug? I'm not saying that religion(s) are false or that the particular God in a religion does not exist. But religion, as far as we know it and practice it...especially when it pivots mainly on "faith" ant that point where we cannot further explain according to our observations, rules and laws (which by themselves could already be utterly misguided and formulated according to all sorts of things, like public opinion, like the words of someone hundreds of years back and upon this history is taken as an authority...etc)...is it also not justified according to...say science or logic? And if one follows science or logic, then do we reach contradictions? Can we take both sides of the fence? Is it good to "not take ourselves too seriously" in such affairs? Or is taking both sides of the fence perfectly fine except it has gotten a bad name?
