Seriously I can't believe I am doing spoilers...its like doing Spoilers for Citizen Kane.
Did Bruce kill Alfred?
My evidence to yes - Alfred felt a tinkle up in his spine, thinking "of course, how utterly perfect" to imply Bruce had chemically poised Alfred to die.
My evidence to No - THE WHOLE POINT OF THE CONFRONTATION WITH THE JOKER is that he could NOT kill the Joker. Why would Bruce kill Alfred but not the Joker?
This has bothered me ever since I read the book over 20 years ago and still bothers me to this day. This question may have been asked before but my brain cannot remember the consenus.
