We came here to study. Evil and good they are connected with each other. If there was no evil, we would not be able to grow spiritually. And only then, when we learn to respect everyone who does not offend or offend, we can go to a better world. All evil in the world is done by the hands of people!
Good and Evil are two sides of the same coin.
In the world, everything is perfect, everyone is in revenge and there is nothing superfluous!
