Once we assuage our conscience by calling something a "necessary evil," it begins to look more and more necessary and less and less evil.

Behind the line

What it means

Our interpretation.

Labelling a harmful act a 'necessary evil' soothes the conscience, and the speaker warns that this comfort erodes judgment. The more we repeat the phrase, the more the act seems unavoidable and the less it seems wrong. A euphemism ends up doing the work of moral reasoning.
