The Wasp Factory - Children; the sexless

I killed little Esmerelda because I felt I owed it to myself and to the world in general. I had, after all, accounted for two male children and thus done womankind something of a statistical favour. If I really had the courage of my convictions, I reasoned, I ought to redress the balance at least slightly. My cousin was simply the easiest and most obvious target.
  Again, I bore her no personal ill-will. Children aren’t real people, in the sense that they are not small males and females but a separate species which will (probably) grow into one or the other in due time. Younger children in particular, before the insidious and evil influence of society and their parents have properly got to them, are sexlessly open and hence perfectly likeable. –p.87
