悪魔的 (akumateki) is a more neutral, descriptive term for 'devilish', while 鬼畜 (kichiku) carries a stronger emotional charge of brutality and is often used in literature or dramatic speech.
In everyday conversation, Japanese speakers rarely use words like 悪魔的. Instead, they might use simpler terms like ひどい (hidoi, 'terrible') or 残酷 (zankoku, 'cruel'). Reserve the stronger words for writing or formal contexts.
