In this scene she never specifically say she kills them. Out of the Trinity, yes she is the most likely to kill but it would have to be a last resort thing for her to do. She shouldn't be jumping to straight up killing people right off the bat.
This romance, this book, everything about it is uninteresting and made of fail. Sales of Justice League have been falling since the Superman and Wonder Woman romance, and recent issues of Superman publicized with Wonder Woman have shown no benefit from the relationship. I can see this book with a good debut because of curiosity and publicity, but overall I think it's a terrible idea. In light of the obvious pop culture pull Superman and Lois Lane have, given the craving critics of Man of Steel had for more Clark/Lois in the blockbuster film, it seems tone deaf on the part of DC to proceed with this relationship and to push it to the extent that they are. I'd rather Wonder Woman get another comic aside from her own that's just about her, like Superman has in his Action book, then for her to be relegated to second billing and love interest. No, thank you.
They really need to give her her rogues gallery back, this god drama stuff is wearing thin. I like what Az has done with some of the gods but I wanna see Diana's rogues in her book and then with that hopefully more feats will come. Give her a city to operate out of and a cast of villains, is that so hard?? Put the gods in the back for a bit and let her show the world all that she can do. DC needs to put some trust in Wonder Woman and not to turn to Superman/Batman every time.
