   Give credit where credit is due.

• Synonym悪党あくとうNeutralCarries a cursing tone 「悪人」 lacks — as in 「この悪党め」; can also mean a gang of villains, or, historically, groups that defied medieval authority.
• Synonym悪者わるものCasualThe everyday colloquial word for a bad person, as in 「人を悪者にする」; 「悪人」 is more objective and can stress an evil heart or deep sinfulness.
• Synonym悪玉あくだまNeutralThe bad side set against 「善玉」, with a comic-strip good-vs-evil feel; also a metaphor for anything harmful, as in 「悪玉菌」.
• Synonym極道ごくどうCasualColloquial for an evildoer or profligate, now mostly an underworld gangster with a yakuza flavor; 「悪人」 has no organized-crime sense.
• Synonym悪漢あっかんWrittenWritten/formal word for a man who does evil, mostly in novels and old-style reporting; 「悪人」 covers women too and can mean an evil-hearted person.
• Synonym悪徒あくとWrittenRare written word for someone who defies morality and does wrong; close to 「悪人」 in sense, but in daily speech 「悪人」 or 「悪者」 is enough.
• Synonym姦人かんじんWrittenRare written word stressing a crooked, cunning heart; 「悪人」 is the general term for evildoers or the evil-hearted and does not single out cunning.
• Related罪人ざいにんNeutralSomeone who has committed a crime, stressing guilt in law or religion; such a person is not necessarily bad at heart, while 「悪人」 targets the person's badness.
• Relatedならず者ならずものNeutralA rogue or hooligan who idles about and stirs up trouble, stressing bad conduct; 「悪人」 covers anyone who does evil, whatever their way of life.
• RelatedごろつきNeutralAlso written 「破落戸」: a street punk or layabout who goes around causing trouble; 「悪人」 is not tied to such a type and covers far more.
• Related凶漢きょうかんWrittenWritten word for a ferocious, violent villain, stressing brutality; 「悪人」 need not be violent — it covers any evildoer or evil-hearted person.
• Related凶賊きょうぞくWrittenWritten word for a fierce bandit or robber, stressing violent deeds like plunder — more concrete than 「悪人」 and rare in everyday use.
• Related姦物かんぶつWrittenWritten word for a scheming, twisted crook, stressing craft and guile; 「悪人」 does not specifically imply slyness and has a wider range.
• Related奸賊かんぞくWrittenRare written word, archaic in flavor, for a treacherous villain; for everyday use 「悪人」 is the natural choice.
• Related匪賊ひぞくWrittenWritten word for bandits who plunder in groups, stressing collective raiding; 「悪人」 is a general term and can refer to a single person.
• Related匪徒ひとWrittenRare written, legalistic term for a gang that uses violence or its members; 「悪人」 requires no gang and describes character instead.
• Related梟雄きょうゆうWrittenWritten word for a cruel, formidable ringleader, typically a figure of turbulent times, tinged with awe — more than just a bad person.
• RelatedよたものCasualColloquial and contemptuous, for an idle punk of bad conduct; it can also brand someone a fool, while 「悪人」 has the wider range.
• Related極道者ごくどうものCasualA term of abuse for a habitual evildoer or a dissolute rake; 「悪人」 is a plain description and carries no hint of dissipation.
• Related奸かんWrittenA single character for cunning wickedness or a wicked person, mostly as a building block in compounds like 「奸臣」; standing alone it is far rarer than 「悪人」.
• Antonym善人ぜんにんNeutralThe antonym: a kind-hearted person, also a naive one who is easily taken in; the two stand opposed in moral goodness of character.
• Antonym好人NeutralThe opposite of 「悪人」 in conduct — a person of good character; when the pair is used as a set, 「善人」 is the usual partner.

For a bad person in general, 「悪人」 is the default; in speech 「悪者」 is the everyday choice and 「悪党」 adds a cursing tone, while 「悪玉」 paints a clear-cut villain against 「善玉」. The written set is rare and often archaic: 「悪漢」 (a man), 「悪徒」, 「姦人」/「奸賊」 (cunning), 「凶漢」/「凶賊」 (violent), 「匪賊」/「匪徒」 (bandit gangs), 「梟雄」 (an awe-inspiring ringleader), 「奸」. 「ならず者」 and 「与太者」 are idle punks, 「極道者」/「極道」 lean dissolute or gangster, 「罪人」 stresses legal or religious guilt. Antonyms: 「善人」, 「好人」.
