Evil and goodness wasn't invented by early human mistakes. People associate these qualities when they are intraspecific with egoism and altruism, which exist even in bacterias. And overall, good and evil is a part of the equilibrium system to preserve harmony and balance. No one species has a special place on the planet that has privileges to break equilibrium with uncontrolled dominance. If humans as part of the ecosystem want to live in harmony they must obey reasonable requirements of coexistence with the universe. So far people live under control of the animal's realm. Their behavior has been dictated by instinctive drivers - blind, unreasonable and limited. Evolutionary behavior strategies also evolve. And for the big brains we have it is necessary to have a better operating system than we have currently gotten from primates. In the animal kingdom equilibrium is preserved by contra forces where too many herbivores will face an increased population of carnivores, parasites, diseases or lack of food. People are part of the same system. With the current operating system (instinctive guidance) we are under control of the same system. But our abilities to break the system by using intellect as a fine and powerful tool in the hands of dumb monkeys don't do any good in the future. We're stretching the delay of the imminent collapse. Only with an upgraded operating system - reasonable consciousness (spiritual awakening, liberated mind, resurrected soul, and other names) can we be naturally controlled from inside without triggering the equilibrium control system of nature. We can't constantly fight all the balancing forces of this system, sooner or later we will break ourselves or create an unsurvivable environment. Our suffering is a result of outdated software that we associate ourselves with. If you feel sad and horrified by looking at dying children from starvation in Africa, you may be aware that their “parents” shouldn't conceive a child in their circumstances, but our primitive drives are unreasonable, can't see Reality and produce desires of pleasure as soon as they see stimuli. Contraceptives are only weakening humans' abilities to have limited self control rooted in cultural norms of morality - hard-won wisdom from generations.
