Batman and Catwoman have had several romantic encounters in the New Earth continuity. Their most prominent love affair is perhaps from the storyline Batman: Hush, in which Bruce finally revealed his identity to Selina and invited her to become part of his life. Things went awry when Batman learned of a massive conspiracy organized by Hush and he decided he couldn't trust in her anymore, ending their relationship. However, in later storylines, like Batman: Heart of Hush, it has been shown that they still loved each other deeply.
Batman's origin story involving the murder of Thomas Wayne and Martha Wayne has been retconned several times. It was originally established that the mugger had been named Joe Chill and Bruce was aware of this. Zero Hour changed this so that his identity was never revealed, symbolically strengthening the potential link between any criminal and the man who killed his parents. Infinite Crisis said that it had been Joe Chill and he had been arrested the very same night, making this the current version. This is expanded upon in a later story which showed Batman slowly driving Chill insane with mental torture before causing him to snap and commit suicide with the bullet meant for Bruce as a child.
Bob made him more insecure, because while he slaved working on Batman, he wasn't sharing in any of the glory or the money that Bob began to make, which is why ... [he was] going to leave [Kane's employ]. ... [Kane] should have credited Bill as co-creator, because I know; I was there. ... That was one thing I would never forgive Bob for, was not to take care of Bill or recognize his vital role in the creation of Batman. As with Siegel and Shuster, it should have been the same, the same co-creator credit in the strip, writer, and artist.
Batman sired a child with Talia al Ghul during their marriage, named Ibn al Xu'ffasch. Dennis O'Neil mentioned that this story was ignored from continuity around Zero Hour because it did not fit in well with the rest of the mythos. Infinite Crisis brings most of this back into continuity with the story Batman and Son by introducing Damian Wayne and stating that Batman was drugged and pretty much raped.
Batman is often treated as a vigilante by other characters in his stories. Frank Miller views the character as "a dionysian figure, a force for anarchy that imposes an individual order". Dressed as a bat, Batman deliberately cultivates a frightening persona in order to aid him in crime-fighting, a fear that originates from the criminals' own guilty conscience. Miller is often credited with reintroducing anti-heroic traits into Batman's characterization, such as his brooding personality, willingness to use violence and torture, and increasingly alienated behavior. Batman, shortly a year after his debut and the introduction of Robin, was changed in 1940 after DC editor Whitney Ellsworth felt the character would be tainted by his lethal methods and DC established their own ethical code, subsequently he was retconned as having a stringent moral code. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.
