I guess I'm not saying he's so much of a good guy, in that he's not really the traditional "bad guy". I don't think laughing at people who crashed in a helicopter is nice but I wouldn't say that makes him a villain. Who were the numerous people he shot that weren't mobsters? I honestly can't remember.
policemen and civilians. Policeman with a shotgun in the truck, civilians shot them while they were driving their car, Patrick Harvey Richard Dent, Rachel Dawes (technically didn't shoot but technically exploded) Killed the policemen that were guarding Harvey dent, possibly killed the nurse who he stole the uniform from and then thats not including the attempts at destroying a whole lot of people with bombs
True, he tormented the guy dressed as batman ( i didn't know he was a police officer) but again, whatever he does/did is off camera. It seemed like alot of the more heinous things that the Joker did were either off camera or were set up and carried out by other people.
It is still all orchestrated by his hands.
I had sort of hoped a R-rated Dark knight was going to come out where they would show a bit more. I thought one of the best scenes NOT in the movie, was in the trailer, when the Joker approaches the prone batman on the street and he ejects his knife. I never did understand that scene. Batman races under a racing transport truck, straps cables to it and a bunch of lamposts but he can't carefully dodge a standing still Joker in the middle of the street.
Rated R won't happen because Batman is a household name
Also he can avoid the truck because he initially planned to go under the truck and then go against the wall. He failed when trying to dodge the joker because he was playing chicken and wanted to frighten the joker but since the joker wasn't afraid of him he turned at the last minute having him loose control and hit the truck which wasn't far behind the joker.
That scene and when he falls from that tower with Rachel and survives the fall made no sense. At least in the script, it says he uses a bat cable or something to break his fall....no idea why nolan left that out. Sorry, i'm getting off topic.
He has super armor that protects things (shrug) maybe his cape helped slow the fall, maybe it was the one true god lending a hand to one of his workers.
