After reading one of my favorite DC stories for a third time in a row, I think Diana could've been written a little better. It does make sense that she and the Amazons are a group of warrior women who've been trained to wage war when war is necessary, but Diana herself is a very compassionate person as well.

In a short interview that Gail Simone did with Mark Waid about her portrayal in Kingdom Come, Mark did say that he could've written her a little better instead of making her come off as a bit of a violent warrior towards the end. https://fivequestionswith.wordpress.com/mark-waid/

There was also, a one single line in the book that still bothers me to this day because it seems half true: "The Amazons believe in peace through strength." Like I said, this seems half true because it really depends on which writer you have for the character who is willing to take this concept far enough. Such as in N52, the Amazons were more warrior women-like and in the Year One issues of DC Rebirth, they seemed more diplomatic but still were warriors who weren't afraid to use it as a last resort.

How Mark Waid portrayed Wonder Woman in Kingdom Come isn't completely out of the norm in my opinion, because she was raised with a sword and a shield in Paradise Island. But that's not all she is about. In the panel where Clark and Diana are talking to each other in space, it is touched upon that Clark admired Diana for her gentility and compassion towards mortals and tells her that she tried her best. I thought that was a great moment, but I just felt like Mark could've fleshed out their relationship more in terms of giving it more meat and potatoes in the dialogue department.

Like, I was thinking in that same panel that Diana shouldn't have said that Amazons believe in peace through strength but more along the lines of "I tried to achieve diplomacy with my sisters in Themyscira for the world of men, but we're going to war now." And Superman could've responded in terms of, "I understand that times are dire right now, but there's still hope for a peaceful resolution." And he tells Diana that he still believes in her to give this world a second chance because she's WONDER WOMAN and loves everything about who she is and what she represents, just like how Diana came to Clark for help in the first issue because she believed in who Superman is and what he represented and that she couldn't do this without him.

But, I did like that scene in the final pages before the epilogue where Diana gives Clark his glasses to help him see more clearly as a man, instead of placing the "Super" over the humanity. Also, she calls him Clark for the first time in that book so I thought that was sweet.

Despite the little shortcomings over Diana as a character in this book, I still believe that her relationship with Clark works overall and it's still one of the greatest DC stories ever told.

TL;DR: Wonder Woman could've been more compassionate.
