You are allowed to contribute to society, but only if you contribute something that can be used by someone however they want it. Otherwise, don't even bother contributing---making products that bring music to the world, or create jobs.
In order to create value in this society some aggressive behavior is typically deemed necessary. But this is win-lose behavior. Is it possible to think of a new, win-win paradigm?
==> Conclusion,
evil = win-lose
good = win-win
How's that for a definition of evil? All of the parent posts make a lot more sense now, to me.
