To be fair, there was that one time he tried to set off a bomb at a kid's birthday party, but prior to the incident with Tim Drake, I'm pretty sure that's the only time even he targeted children. In fact, it's one of the few occasions I can think of where any of the more prominent villains targeted children in the whole series. So yeah, all the more reason that the Sewer King's horrid treatment of them stands out as unique.
