An evil custom is to be abolished.

Explanation

No custom or practice, however long-standing, can survive once shown to be contrary to right — duration does not convert wrong into right.

Where this applies

• A longstanding practice of racial discrimination must be ended regardless of how old it is.
• A custom of ignoring safety regulations has been going on for years — it still needs to stop.
