Evolution is an imperfect and often violent, abrupt process. A battle between what already exists, what is yet to be born, and what the future holds. And in the midst of these birth pains, all morality loses its meaning. Good ... Evil ... Right ... Wrong, all reduced down to one simple choice: Survive, or perish.
When evolution selects its agents, it does so at a cost. It makes demands in exchange for singularity, for sentience, and you may be asked to do something against your very nature. Some of us resist evolution, and end up being lost in isolation or slip through the cracks. But for those who submit, the sudden changes in their lives that should be wonderful comes as a betrayal. It may seem cruel, amoral, but the goal is nothing short of self-preservation and survival. This driving force, evolution, is not sentimental, neither does it have the stomach for morals. Like the Earth itself, it only knows the hard facts of life's perpetual struggle with the cycle of Death himself. All you can do is hope, pray, and trust that when you have served its needs faithfully, there may remain a small glimmer, a shred of the life you once knew.
Man imagines himself the agent of his own destiny, capable of determining his own fate, and cheating Destiny. But have we truly any choice in when we rise or fall? Or is it a force larger than all of us that bids us direction? Or is it some divine force which intervenes, keeping us safe? For all his bluster, it is the sad providence of Man that he cannot choose his triumphs, and cannot foresee his failures. He can only choose how he will stand when the call of destiny arrives, hoping that he will have the courage to answer.
