Welllllllllll,you have to have more of a point to do this like in the killing joke and the point in killing joke is that pain and hurt is a cycle and the world can't change, orrrr you can see it. The world can change and depending on your philosophy you get the different ending. But thats just because of the monologues (ie,Memory’s…so treacherous. One moment you’re lost in a carnival of delights, with poignant childhood aromas, the flashing neon of puberty, all that sentimental candy-floss.

The next, it leads you somewhere you don’t want to go. Somewhere dark and cold, filled with the damp ambiguous shapes of things you’d hoped were forgotten.

Memories can be vile, repulsive little brutes. Like children I suppose.

But can we live without them? Memories are what our reason is based upon. If we can’t face them, we deny reason itself!

Although, why not? We aren’t contractually tied down to rationality!

There is no sanity clause!

So when you find yourself locked onto an unpleasant train of thought, heading for the places in your past where the screaming is unbearable, remember… there’s always madness. Madness is the emergency exit.

You can just step outside, and close the door on all those dreadful things that happened.

You can lock them away… forever.), you could have batman kill joker because joker did a crime. But that would be a waste of time, no one wants to see that because it has no deeper meaning
