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.
Pérez and Potter wrote Wonder Woman as a feminist character, and Pérez's research into Greek mythology provided Wonder Woman's world with depth and verisimilitude missing from her previous incarnation. The incorporation of Greek gods and sharply characterized villains added a richness to Wonder Woman's Amazon heritage and set her apart from other DC heroes.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
