Whether or not this is merely to torture the mother through emotional detachment is debatable, but it's still better than the yukkuri growing up dumb, singing badly, shitting everywhere, and not understanding logic.
c'mon coker, see the bright side, at least that Koreimu may have a positive future, instead of being dumb as hell and die in a dumb way after a short and dumb life.
