"Arrogance, pride, anger, conceit, harshness and ignorance-these qualities belong to those of demonic nature, O son of Prtha." [Bhagavad Gita, Chapter 16: The Divine And Demoniac Natures] https://asitis.com/16
Only if people develop real Krishna Consciousness(God Consciousness) and not some demoniac form of so called religion like blowing up people with suicide attacks can the situation be improved. Because if everybody is of demoniac nature it will be hell on earth. The demoniac forces are now prevalent on earth and are creating all the pain and suffering for the living beings.
