And that's exactly the problem. It begins to get rather ridiculous after awhile. The Joker kills a a bunch of people. Batman beats him up. They throw him in Arkham. He escape. He kills double the previous amount of people. Batman beats him up. They throw him in Arkham. He escapes. He kills even more people. Batman beats him up. They throw him in Arkham.
It's too unrealistic, even by comic standards. This guy CONTINUALLY escapes, his violence rises every time. And the city REFUSES to kill the guy. Batman refuses to cripple the guy or kill him EVERY TIME! I mean, really? It gets old. That's what happens when you rely so much on one character and milk him for all he's worth. You begin to over-do everything. So DC won't kill the character because of loss of money. But i think a story in which Batman finally decides to kill him would be very interesting. How would that effect Bruce and co.? And being as how DC would never keep him dead, how would The Joker's return throw any changes made into chaos?
....yeahhhh. If you were talking about a one-shot, or an elseworlds, then yes, it would be a great idea. You could do some really interesting things with it.
But you have to remember that comics are a medium that never stop. Killing the Joker would be a great
one-shot. Notice the use of
ONE. There. Because that's all it would be. Once. And then you can't do anything. And if you were just going to have him come back, then why do it at all, because if you make a huge deal of his death, only to have him come back, the entire story you built around his death is pointless, since it really has no effect on the characters in the long term at all.
And you think a criminal who escapes continually is more unrealistic than Batman conversing with a man who's from another planet, yet looks just like a human but can fly, shoot lazers out of his eyes, has super strength, speed, x-ray vision, and can freeze people with his breath...or the fact that their universe used to be seperated into multiple realities and there were multiple versions of the DC heroes, or the fact that Batman has somehow managed to master almost every form of martial arts, while still being a master of crimonolgy, multiple scienes, has olympic level dexterity and acrobatic ability and yet can somehow still bench over 500lbs....
I could go on and on. It's a comic book. The very character of Batman himself defies all logic. They're
FANTASY. Yeah, in real life the Joker would be dead, but he's not dead right now because he's one of the most compelling fictional villains ever created. You don't kill off villains like that.
