Wicked
Middle English: probably from Old English wicca ‘witch’ + -ed1.
wiktionary
From Middle English wicked, wikked, an alteration of Middle English wicke, wikke(“morally perverse, evil, wicked”). Possibly from an adjectival use of Old English wiċċa(“wizard, sorcerer”), from Proto-Germanic *wikkô(“necromancer, sorcerer”), though the phonology makes this theory difficult to explain.

etymonline
wicked (adj.)
c. 1200, extended form of earlier wick "bad, wicked, false" (12c.), which apparently is an adjectival use of Old English wicca "wizard" (see witch). Formed as if a past participle, but there is no corresponding verb. For evolution, compare wretched from wretch. Slang ironic sense of "wonderful" first attested 1920, in F. Scott Fitzgerald. As an adverb from early 15c. Related: Wickedly.
