The Buddhist concept of mudita -- "empathy," "sympathetic joy," or "happiness in another's good fortune" -- is cited as an antonym of schadenfreude [Ref 1]. Alternatively envy (German, Gluckschmerz), or "unhappiness at another's good fortune," could be considered schadenfreude's counterpart. Other antonyms such as empathy, pity, and compassion are "unhappiness at another's misfortune."
