There is an old Igbo folktale that my late father loved to tell whenever the moon was full and the village square echoed with the laughter of children. Whether the story was history or imagination never mattered, for our fathers believed that wisdom often hides inside stories more securely than it hides inside facts. They told of a peaceful community nestled between two streams and protected by an ancient iroko tree whose branches had witnessed generations come and go. It was said that in those days the people hardly knew the meaning of suspicion.

Farmers left their yam barns unlocked because every man was content with the harvest of his own sweat. Women returning from the stream could leave baskets of cassava, vegetables and firewood by the roadside and return hours later to find them untouched. Children wandered freely from one compound to another because every elder regarded every child as his own. At sunset, families slept with doors only gently pushed together, not because they were careless but because trust had become the invisible fence surrounding the village. Then, one harmattan season, a stranger arrived. He smiled like every other traveller, greeted the elders with uncommon humility and was welcomed according to the sacred African law of hospitality. But before the first moon completed its cycle, goats began to disappear. Yams vanished mysteriously from barns. Palm wine jars were emptied before dawn.

Fear quietly entered the village before anyone recognized its footsteps. Suddenly the blacksmith found himself forging stronger locks and heavier iron bars. Young hunters who once pursued antelopes were recruited to patrol the village at night. Elders established councils to investigate disputes, while messengers were appointed to carry intelligence from one community to another. During the following New Yam Festival, the oldest man in the village rose slowly, rested both hands upon his carved walking stick and uttered words that have echoed across generations: “The stranger did not make our village prosperous; he merely forced us to become wiser.” That ancient African tale, whether true or imagined, captures one of the greatest paradoxes of human existence. Evil has never been creative, yet humanity has repeatedly demonstrated an astonishing ability to convert the challenges created by evil into opportunities for innovation, organization and progress. It is a paradox that neither celebrates wickedness nor excuses it; rather, it celebrates the resilience of the human spirit.

Centuries after that imaginary elder spoke beneath the village iroko tree, the Greek philosopher Plato would argue in The Republic that justice is the foundation upon which every enduring society must stand. His greatest student, Aristotle, would later observe that the purpose of the state is not merely to enable people to live but to enable them to live well. Many centuries later, the English philosopher Thomas Hobbes, reflecting upon the chaos of civil conflict, painted a frightening picture of humanity without laws, describing such a condition as one in which life would become “solitary, poor, nasty, brutish and short.” Although these thinkers lived in different ages and civilizations, they all arrived at a common conclusion remarkably similar to the wisdom of that unnamed Igbo elder: social order is not accidental; it is humanity’s deliberate response to the ever-present possibility of disorder.

Indeed, civilization itself may be understood as mankind’s continuous struggle against the destructive tendencies hidden within human nature. Every constitution ever written, every court ever established, every police force ever organized and every prison ever constructed stands as silent evidence that humanity has never underestimated the capacity of man to become the enemy of his fellow man. Yet here lies the irony that philosophy dares to examine. The very crimes we condemn have compelled society to build institutions that protect civilization. This observation does not honour the criminal; it honours the ingenuity of those who refuse to surrender to criminality.

The first lesson that emerges from this paradox is that human wickedness has unintentionally become one of the greatest teachers of civilization. If there had never been theft, mankind might never have discovered the necessity of secure property rights. If there had never been murder, the sanctity of human life might never have been defined with such solemnity in law and religion. If deception had never existed, truthfulness would hardly have acquired the moral prestige it now enjoys. The German philosopher Georg Wilhelm Friedrich Hegel argued that history advances through contradictions. According to his dialectical understanding of reality, progress often emerges from the collision of opposing forces rather than from the uninterrupted triumph of harmony. Although Hegel was not celebrating evil, he recognized that conflict frequently compels humanity to discover higher forms of order. In a similar manner, every criminal act becomes an involuntary challenge that forces society to strengthen its legal institutions, improve its moral consciousness, refine its administrative structures and invent more effective mechanisms for protecting justice. Wickedness may initiate disorder, but civilization repeatedly responds with greater organization. Thus, history becomes not merely the record of crime but the record of humanity’s refusal to surrender to crime.

The French philosopher Jean-Jacques Rousseau once declared that “man is born free, but everywhere he is in chains.” Those chains, in one sense, are the laws and institutions that regulate human behaviour. Many people complain that society has become excessively regulated, forgetting that every major regulation has a historical story behind it. Aviation laws were strengthened because aircraft crashed. Banking regulations multiplied because fraudsters exploited financial systems. Medical ethics became more rigorous because lives had previously been endangered by negligence. Cyber-security has become one of the fastest-growing professions in the world because cybercriminals have transformed the digital landscape into a battlefield. Ironically, millions of honest men and women now earn dignified livelihoods as judges, lawyers, forensic scientists, police officers, cyber-security experts, intelligence analysts, insurance investigators and correctional officers precisely because society refuses to capitulate before criminal ingenuity. The existence of these professions should never be interpreted as gratitude to criminals, but rather as testimony to humanity’s extraordinary capacity to transform danger into disciplined service.

Even religion, whose highest aspiration is the triumph of righteousness, has often grown stronger whenever wickedness has appeared to prevail. Throughout history, seasons of persecution have frequently produced deeper convictions, greater solidarity and renewed spiritual awakenings. The early Christian community expanded despite relentless persecution by the Roman Empire. The Hebrew prophets found their prophetic voices in periods of national corruption and moral decline. In African traditional societies, communal rituals of reconciliation, purification and covenant renewal often emerged after periods of conflict and betrayal. Darkness has repeatedly forced humanity to appreciate the value of light. As the Chinese sage Lao Tzu observed, “Difficult and easy complete each other.” The statement is not a celebration of evil but an acknowledgment that human understanding often becomes clearer through contrast. Virtue shines most brightly when vice attempts to extinguish it.
