As noted elsewhere, I was not aware of what particular wall it was and took it to be a call for summary executions of bigots in general. I absolutely do think that royals should not exist and should be punished for their crimes against humanity.

When it comes to the the children there, that was just murder though. Strip them of their titles and, if they commit crimes, try them for them, as was done in China (though I do think that he was let of lightly for his crimes in Manchuria).
