Long ago, at the very beginning of Roman civilization, there were kings. One king, Tarquin Superbus, took the royal prerogative a bit too far and blackmailed a noble matron named Lucretia into sleeping with him. (He tells her that he will kill her and his slave, then tell her husband he found them in flagrante.)
She, to take back her honour, and keep Tarquin from blackening her name, sent word to her husband of what had happened, and killed herself. A dissident noble named Brutus used her death to start a civil war and depose Tarquin, thus beginning the Roman republic.
Don’t get me wrong, I like Batman and all, but I don’t see why every DC comic has to be equally grim and dark. Surely each should have its own feel? (The same should be true for the movies, by the way. I remember describing Man of Steel to a friend as “Superman Batmanned”.)
So thank goodness for Barbara Gordon, whose Batgirl takes a completely different route. This isn’t to say that she doesn’t have difficulties, or face challenges. She just handles them differently.
