User blog comment:BeholderofStuff/Joker (2008 Graphic Novel) a CM or Not?/@comment-27818776-20150427230311/@comment-2059440-20150427230444

let's not forget in Killing Joke he also had a geniune heart to heart with Batman and since we know Joker values Batman this is very likely Joker being "truthful" : didn't change the fact his actions in Killing Joke made him a CM.
