I've been through this, with university philosophy professors. a) Morality is not viewpoint dependent. An repugnant act is not suddenly acceptable if the perpetrator lacks moral reasoning capabilities. While we do not hold insane people responsible for their criminal actions we do, in fact, stop them from doing it. b) Morality is not dependent upon extenuating circumstances. If I murder you and steal your last loaf of bread because I am starving, it may be understandable but it is still murder. c) The moral cost of not performing the genocide pales compared to the established moral cost (for the purposes of this discussion) of allowing the ongoing, millinia long "murder" of the prey animals to continue for untold generations to come.
