means The quality or state of being deliberately bad — moral wrongness, especially the kind that's knowing and intentional rather than accidental.

from From 'wicked,' which emerged in Middle English — likely a development from Old English 'wicca' (meaning 'wizard' or 'sorcerer,' the root of 'witch') blended with or shaped by 'wick,' an old dialectal word meaning 'evil.' The connection to witchcraft is fitting but not fully settled by scholars — what's clear is that by the Middle Ages 'wicked' had hardened into a general word for morally depraved, and '-ness' simply bolted on to turn the quality into a noun: wrongness made into a thing you can have, and apparently flaunt.
