Mass extinctions aren’t unusual on this planet. In fact, it helps to drive evolution. Life has always changed itself to adapt to the world around it. However, Lilin changes the world instead of itself. And so it performs rituals to evolve itself artificially. It sacrificed older life to create new lifeforms blessed with the Fruit of Life. All of this is an act of extinction that has been programmed since time immemorial. NERV calls this the «Human Instrumentality Project».
