"Whenever a group of people start believing they are better than everyone else, the results are always the same." This is the first evil, which has many variations. One example is "I against my brother. I and my brother against my cousin. I, my brother, and my cousin against the world"; another example is any form of sectarianism such asa group'snationalisticor cultural ambitions.
The second evil, is a mis-perception (often socially imposed)that we need to become somebody else (e.g., Albert Einstein, Bill Gates, Elon Musk, and my handsome neighbor) except to be ourselves. This perhaps is the greatest obstacle that consciousness evolution is facing on this planet.
