The unnamed slavers from "Fairy Tail" perhaps?

 * Enslaved masses of people, including children.


 * Punished them for as much as attempting to flee.


 * Are compared with one of the worst "Higurashi" characters.

Their full crime list:
 * The slavers who forced thousands of captives to build the Tower Of Heaven. They employed even children (among which, Jellal and Erza) to do this work, starving them almost to death, punishing and killing them over the most insignificant slight; and they weren't above some torture as well - it was because of a particularly brutal beating from them that Erza lost one of her eyes. Killing them all was obviously Jellal's making as a villain, but they deserved it.
