While I generally like my heroes with a no kill policy (admittedly it worked a little better when the villains were more inclined to rob banks and make goofy deathtraps than burn down orphanages and rack up massive body counts) Diana does offer a nice, realistic contrast. I just wish Superman and Wonder Woman's conflicting views were portrayed in a way that didn't end up making Supes look ineffectual and/or Diana bloodthirsty more often (the former often seems to happen more often than the latter, despite Batman's haranguing and foot stomping).
