10 Worst Things DC Has Ever Done To Harley Quinn
6. Have Her Appear In Death Of The Family
As if the entire assorted nightmare fuel of the rest of the Death of the Family series wasn't enough, it included a scene between Harley and the Joker that would be impossible to read on a full stomach.
Not only is Joker back in full spousal abusing form, but he also commits entirely at this moment to ruining Harley's life. He attempts to submerge her in acid, bites off her ear, reveals he's infected their pet hyenas with rabies, and - worst of all - shows Harley at the end of the issue that he's had various other Harleys, and appears to have killed every last one of them.
While it's maybe preferable to write the scene off as his attempting to convert her to his side by destroying her remaining sanity, there's also a pretty good chance that Joker's lines about Harley aren't actually a joke, and that many have suffered the fate of being the Joker's sidekick.
It's an effective way to get Quinn to officially cut ties with the Joker, but it also makes her feel like an insignificant peon - which is maybe a less than stellar move.
