If you must have an evil, choose a little one.

Understand the thought

Meaning in plain English

When every available option has a drawback, the saying favours the one involving less harm. The qualification matters: first examine whether the choices are genuinely limited, and do not treat a lesser harm as harmless or automatically justified.

What the words are saying

The opening if makes the proverb conditional. It describes a situation in which avoiding every bad consequence appears impossible, then asks for a comparison between the available alternatives. A useful reading identifies who would be affected and what the actual drawbacks are, rather than accepting a vague claim that one option is smaller. An additional route, a delay or outside help may change the choice. Even when the options remain constrained, the lesser harm still deserves mitigation and accountability. The proverb does not grant permission to impose an avoidable loss on someone else merely because a worse possibility can be imagined.

Everyday example

When two unavoidable maintenance dates both disrupt a club, the organisers compare who is affected and choose the date with a workable alternative room.

When to use it

Use it when genuinely constrained alternatives need a careful comparison of their consequences.
