As a species evolves it must pass the reins from warrior to the nurturing class else the same beastial drive which allowed it to climb to the top of the food chain will also allow it to continue until it has also consumed itself in cycle. Similarly it is our most active whom challenge our form and keep us fresh. These are simple knowledge we must hold dear, for we are a work of art still in progress and we are even lethal to ourselves.  If we don't look inward we will never mature into beings whom might survive this test.
