There is no moral right and wrong. The only truths are that which can be proven with science, physics and mathematics

By all conventional standards of evil, human society itself is the most evil entity that has ever existed in the known universe

How many people have been killed, kidnapped, tortured, raped, beaten, imprisoned by governments and militaries of the world throughout history and today?

Take an institution like that Catholic Church. How many innocent people, "heretics" and pagans were brutally tortured to death in the inquisition? And still the Catholic Church is considered a "holy" institution, that many law abiding adults follow

Compare this to the insignificant "crimes" of individuals considered evil in society, such as killers and rapists

If you steal someone's money at gunpoint it's called robbery. When the government takes someone's money at gunpoint, it's called taxation

If you have a dispute with your neighbour and shoot him, you are an "evil murderer". If a government has a dispute with another government, they can send thousands of men to kill thousands of strangers, and that is called "war", and the killers are considered "heroes"

There is no such thing as punishment, there is only revenge. Punishment implies there is moral authority possessed by the punisher, when in reality there is no moral authority, only superior physical power
