For an objective statement about a bad person, choose 「悪人」; in casual speech say 「悪者」. 「ならず者」 fits idle troublemakers, 「極道」 and 「ギャング」 the underworld, 「罪人」 actual criminals, 「人でなし」 the heartless, and 「悪玉」 the bad side in good-versus-evil talk. The written/formal 「悪漢」「悪徒」「凶漢」「凶賊」「姦人」「奸賊」「匪賊」「匪徒」「梟雄」 are literary or archaic; 「極悪人」 is far stronger. Antonyms: 「善人」, and written 「君子」.
