The greatest species to have evolved on the planet Earth. Only species to have developed coherent thought, conscience, faith, and the ability to destroy every last one of itself and the planet it inhabits. Only species to reach to the stars and land on the moon. Greedy, selfish, self-serving, and yet kind, compassionate, and edifying. Driven by hate, love, and power. Has the power to create and the power to destroy. Once humanity settles other stellar objects it will likely never go extinct.
Beyond the natural 'necessities' to survive and reproduce, every human's ultimate purpose is to further the spread of humanity and civilization to every corner of the Earth and the universe. Aggressive to a fault, and too intelligent for it's own good; however, some day, it may save the Earth that so long endured punishment at the hands of the human cancer. Humanity is not a plague. Western society is. However, it is the only way, and progress comes at a price. Some day the Earth will fully heal.
Intelligence is a gift to homo sapiens, the thinking man. However much we may abuse it it is better for good than evil, and some day it will shine through.
Humanity is beyond good and evil, since every individual is neither a saint nor a devil. These things we exist for are petty compared to the furtherment of advance and progress. Humanity is stupid. People are stupid. A person is smart. Democracy leads to this excess and waste, the destruction of the planet, because of the assumption, that a million people, are smarter than one.
