I wonder if there’s a kanji for Horcrux. Probably not.
But the Chinese do have a point - its a little like the way Southerners honor their war dead. Is it possible to honor them without honoring slavery? Seems like the jury is still out on that.
Likewise, Japan has its heroes, who were also war criminals, some of them. Its tricky to honor the fallen without legitimating their crimes. Not exactly Voldemortian, but touchy and complicated.
