Even alongside all of her kindness, compassion, and empathy, Diana is still also a warrior at heart, and when someone she cares about is hurt, becomes far more relentless and ruthless. When seemingly beaten by Ares (who was only growing more powerful from her violence, rage, and hatred), and after having to watch her beloved Steve Trevor die, she flew into an agonizing rage, and she assaulted and brutalized several armed German soldiers with immense speed and ferocity. She even came close to murdering Dr. Poison as vengeance for Steve's death; but after recalling Steve's great love for an undying belief in her and her beliefs, restrained herself and refocused her energies on Ares, harnessing her love for Trevor to overcome her violent emotions and swiftly overpower an angered Ares. Additionally, she resolved to fight even harder after Steppenwolf revealed that he had killed several other Amazons. Outside of battle, however, Diana can also react indigently and negatively towards people who disrespect her, her relatives, or those she cares about. Two such notable instances were when she shot an angry look at Lex Luthor (after he insulted her father Zeus's memory), and when she shoved back Batman (after he had insulted her beloved Steve Trevor's memory). Diana also remains ruthless when facing enemies in battle as Wonder Woman, and she even shows signs of enjoying a good battle when they put up a good fight. This was seen when she briefly smiled and laughed when she was beaten to the ground by Doomsday, and smirked as she stopped the first bullet fired at a group of hostages in London.
Without giving too much away, and not knowing how this plot point relates to Dark Nights: Metal (I’m sure it does somehow), I’m even more annoyed by Jason than ever. A plot point occurred to grant him potentially greater powers than Wonder Woman, or at the very least a much wider variety that he is able to access with ease. He’s starting to feel overpowered, and in a cheap way at that. His character arc is really starting to undermine years and years of history and hard work that Diana’s creators, and Diana herself, have done. As long as Jason is a part of Wonder Woman’s story, well, sorry… but I’m just not that interested.
While living in "Man's World" for a century following World War I tempered some of Diana's more blindly held beliefs, she still held true to her core values of kindness and compassion, and further grew into an exceptionally considerate, diplomatic, and empathetic woman. This can be seen when she silently emphasizes with Lois Lane after the death of Superman had been killed (recalling her own pain after Steve Trevor's sacrifice), smiling knowingly when Aquaman accidentally sat on the Lasso of Hestia and confessed his fears about their upcoming mission and how attractive he found her. With all of her experiences, Diana is also the most diplomatic member of the Justice League, as evidenced by her treatment of the Flash with compassion and patience, despite his tendency to somewhat annoy her and the other Justice Leaguers with his humorous attitude, and the kindness and support she showed to Cyborg while he continued to grapple with his powers. Indeed, through her compassion and unbreakable spirit, Diana has given renewed hope to many of her teammates throughout the years. For example, she motivated and inspired the Wonder Men into looking past purely monetary interests, with Chief resolving to no longer be neutral in the war, Sameer finally admitting his passion for acting, and even the depressed Charlie struggling with PTSD finally beginning to sing again for the first time in years. Likewise, during the Justice League's battle against Steppenwolf's forces, Wonder Woman was able to inspire confidence in the inexperienced Flash and Cyborg, assuring them that they wouldn't need to fight the Apokoliptan invasion alone. Furthermore, she was the most understanding of Superman's confusion upon his ressurrection and remained ambivalent about fighting the newly-resurrected Superman and even implored him not to force her to, showing him compassion and persistence while attempting to get him to remember who he is (even calling him by his birth name). In addition to her general willingness for empathy, however, Diana is also extremely friendly and can step back enjoy the smaller moments in life, as seen in her utter delight in experiencing ice cream and agreement with Superman (who, up until this point she had not spoken to much) about him not missing out on the positive results of their victory over Steppenwolf.
Diana sees Sir Patrick Morgan in the base, who reveals himself to be the true Ares, and tells her of his plan for a world without humanity by having them destroy each other. Ares proposes that Diana help him accomplish his vision of paradise, but Diana promptly refuses, not wanting to kill billions of innocents. Ares then reluctantly engages her in an epic battle while Steve and his comrades attempt to dismantle the plane harboring the mustard gas.
