The rapist wasn't the most notable one, he was (if Jason did it) the only one.
And what many people tend to forget is that is that Batman wasn't much better during that run.
- In Batman 414 you had him brutally beat up a guy, of whom he thought that he was a serial killer (he wasn't).
- Ten Night of the Beast he trapped KGBeast and left him to stave (Ok that one was retconned later)
- in the Cult he actually killed someone (while he was under the control of Deacon Blackfire), and later let Blackfire get killed by his own men
It was in general a very dark a gritty run.
