What is universal in the human being is his vain, hypocritical and greedy manifestations. This today as yesterday, and yesterday as tomorrow. There would be exceptions if the human being were not thrown, as a rule, into situations of pressure and risk, when he is forced to act by the instinct maliciously developed over the centuries and capable of freeing him from more severe discomfort. The world does not allow him peace: it hunts him and demands a reaction. And the reaction, always, manifests itself in vanity, hypocrisy and greed—the defense mechanism that corrupts souls and becomes vice. So it would be good that behavioral psychology uses moralistic philosophy as dogma: however, doing so would invariably lead the student into depression.
