This book has investigated numerous phenomena of human destructive behaviors, and we have seen how much such behaviors have contributed to human suffering, agony, and aggression. And we try to answer why we behave destructively. There are myriad answers to that. But the most prominent answer is when God created the universe and humankind, the first program that was instilled in us was the human wicked, or destructive, inclination, before anything else. So since God the Almighty instilled in us such a wicked program, then we are doomed from the start. You may go further and say that it?s unfair that we come to this world with a bad start. As the existential thinkers put it intelligently, our existence is merely a cruel trick.
