Most people were not around back in the 30's and 40's and most people know Batman as someone who would NEVER kill under any circumstances.Thats why Burtons Batman movies turned people off because Most people know Batman as the guy who would never take another life no matter how evil they were.That batman that Bat dude mentioned,yeah he killed, but that was when he carried a gun,when he stopped carrying a gun,he did not kill people anymore.Thats why I have a problem with Burtons Batman movies because Batman did not carry a gun in those movies and of course the Batman that stopped carrying the gun in the comics,did not kill anymore.Like it was already mentioned, Batman killing people like The Punisher is a big turn off to many batman fans.
