One of the most stringent codes that batman and the bat family follow is the no killing principle.What would have been the consequences if he didn't adhere to such a code? Would he be turned into a punisher type vigilant who takes Jo prisoners and mostly operates alone instead of creating a family? Would he have eventually gained the cops and other heroes tolerance if not support or would he have been hunted down? Can a batman killing inspire more fear than a non killing one or would he lose the mythical element and just solve problems with brute force which would make scum fear his brutality but not have the mythical fear that he inspires? Would he be able to keep himself functioning or would he turn into a sociopath who doesn't have any feelings left and just lives for his next mission or kill?
