Inhumanity

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

That the desires of the majority of the people are often for injustice and inhumanity against the minority, is demonstrated by every page of the history of the whole world.

John Adams quotes 

The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them; that's the essence of inhumanity.   George Bernard Shaw
