Ethics

One of the main objectives of ethics is to provide a neutral (efficient) space (reasonable morals) of interaction between particles-subjects.

But:

“The first rule of ethics is this: If you see a fraud and don’t talk about the fraud, you yourself are a part of fraud. To be nice to an asshole is no better than to be asshole to a nice person, and in the same way to tolerate someone who does vile things is to indulge in those vile things.” -N.T

Yes, evil things strictly require proper (not silent) answer; that necessarily balances the relationship-moral reality fields.
