Perhaps one day killing will be seen as "getting one's hands dirty" and unecessarily organic in an otherwise square, cold, sterile, sharply edged world. Killing will not stop for morals but rather for reasons of seperation. Meals will be perfectly produced homogenous mixtures of 3d printed amino acids, vitamins, and sacchatides. Yeah.. I dont have much faith in the ability for people to trade pleasures for lives.
