Newsarama has a great interview with John Ridley, writer of The Other History of the DC Universe. If you weren't already planning to read it, the interview might make you want to, and if not Ridley's words, the awesome art (especially the layouts!) might persuade you.
Anyway, one of the moments he's touching on in one of the five issues is Diana killing Max Lord. When I first read that, my reaction was, as it always is, "Why can't that story go away?" But as I read on, later in the interview it becomes clear that he's not going to be looking at it from a "Was she right or wrong?" way. Rather, Ridley says:
I've been excited for this series, and the interview makes it sound like it's going to deliver on it's promise of multifarious perspectives.This may not be straight with the Justice League, but when Wonder Woman did kill Max Lord and she's like, 'I got to do what I got to do. I'm a warrior and I'm going to do it.' People freaked out about that, and that's something that we do talk about in this series. Did they freak out because Wonder Woman did it, or did they freak out because a woman killed a man on live TV? There are other male heroes killing male heroes.
