So we all have our own interpretation of the character and how we want him to be written but there's mainstream Batman ideas that are have been cemented into the character's blueprint. I want to know if you have any that you feel don't work.

Mine is the idea that the reason Batman doesn't kill is because he's afraid it'll consume his already fragile mind and turn him into a compulsive murderer. I always see people using this reason and pointing to that moment where Batman explains why he won't kill the joker to Jason. I never like that idea first because I'm not a big fan of stories that lean too much on mentally ill Batman and also because I always prefered to believe that he doesn't kill because he value human life too much. To him it shouldn't really matter if he can or can't stop with just one I'll always believe Batman doesn't want to kill period even if he could stop just with Joker.
