It is a part of another layer of adaptive means between nature and the need to survive. When this species will survive it has to adapt and especially it must adapt to the self created change in nature when we as a species dominate and loot a planet. It might look less harsh when mass death occurs when it is in the name of a superior will. When you ruin your life it is always more easy to blame somebody else instead of admitting you were an idiot? And since we are unable to stop our own growth beyond any reasonable size as a species we let people die better in the name of a cryptic superior plan than according to substantial mental issues as a race, do we?
